Everyone who works or plans to start working with HA is faced with the question of how to cut drywall. There are several ways to perform this simple and at the same time difficult operation.
The most popular is cutting plasterboard sheet in a straight line. To do this, the gypsum board is placed on flat surface to a horizontal position. After this, using a pencil and a rule, a straight line is marked along which the incision is made. Then the sheet is turned over and cracked along the cut line on the other side. To understand how to cut drywall correctly, we will consider all situations and cutting methods in more detail.
First, let's decide what tool we need for this operation. How to cut drywall:
- Regular or special drywall cutter with interchangeable blades
- Roulette
- Ruler, rule or cord for marking
- Jigsaw with a fine file (for cutting sheets along uneven lines)
After cutting the plasterboard sheet, its edges will need to be processed, so for this we will use:
- Chamfering plane
- Roughing plane
How to cut drywall in a straight line
Cutting plasterboard in a straight line is not that difficult. To do this, lay the plasterboard on a flat horizontal surface (on the floor or on a table), do necessary measurements using a simple pencil. It should be noted that it is not recommended to use a marker or pen for marking, as they leave marks that are then almost impossible to putty on.
After measurements, we leave marks at the bottom and top of the sheet. We apply a rule or level to these marks and draw a line.
Now let's start cutting. For this we need sharp knife with adjustable blade length. In this case, the blade should protrude from the knife handle to a length not exceeding the thickness of the drywall. We make a cut along the left line. In order to make the line more even, you need to go over the cut with a knife 2-3 more times, this way we will deepen it.
If the sheet was lying on the table, then it is necessary to move it so that the part to be cut protrudes beyond the edges. Now you need to grab the edges of the sheet and sudden movement Gently break along the cut line, after which we make another cut with a knife from the back side.
If cutting the plasterboard sheet was carried out on the floor, then after making the cut it must be placed on its edge, and by lightly tapping on the whole side, make a break and then cut the cardboard with a knife.
Note! Do not use a circular saw to cut drywall. Using this tool can be compared to hammering nails with a stone. Such a saw creates a huge amount of dust, which has a detrimental effect on the mechanical parts of the tool and on your lungs.
How to correctly cut drywall in the shape of the letter L
Typically, a plasterboard sheet is cut in the shape of the letter L to cover a doorway. The operation is not complicated, but to perform it we will need a hacksaw, which we use to saw through the short part. The long part is cut according to the pattern described above with a knife.
How to cut drywall along an uneven line
A more complex process of cutting drywall along a curved line, for example when we need to cut an oval or circle. For this work we will need an additional tool - jigsaw with a fine file. You can try to cut the sheet with a knife, but there are very few guarantees that the cut will be smooth and neat.
When cutting drywall with a jigsaw, a lot of dust is generated, so you need to take care of the tools personal protection(safety glasses, respirator).
How to properly cut drywall installed on a wall
If it is necessary to sheathe with plasterboard sheets window slope or a corner of the wall and at the same time make sure that its edge perfectly coincides with the edges of the wall, then the cutting of the gypsum board is carried out “on the spot”, that is, the sheet already installed on the wall is cut. As a rule, to do this, attach a piece of drywall a little larger size than necessary and after that the unnecessary parts are cut off.
To perform this operation correctly, the plasterboard sheet must be securely fastened to the frame. The cut is made along the side of the sheet that is adjacent to the surface to be sheathed. We draw along the outlined line several times, lightly pressing on the unnecessary piece. After this, we cut the sheet from the reverse side. In order to cut a sheet in the shape of the letter L on a sheet already attached to the frame, we cut a horizontal line with a hacksaw, after which we cut a vertical line with a knife.
How to cut a hole in drywall for an outlet or light bulb
Such holes are cut in plasterboard sheet usually after installing it . How to cut drywall in this case?
For this operation we will need a drywall crown (circular saw) or a drywall hacksaw. IN construction stores you can purchase a set of crowns for HA different diameters. These devices are installed on a screwdriver or drill.
Cutting a hole with a hacksaw is more difficult, and the edges of the hole will not be as smooth.
Processing the edges of drywall after cutting
After cutting, the edges of a sheet of drywall are usually not very even and smooth. To make them more accurate and at the same time prepare the joints of the installed sheets for puttying, you need to chamfer them with a special plane. This can be done using a regular knife. Typically, the chamfer is removed at 2/3 of the sheet thickness at an angle of 45 degrees.
Cutting drywall correctly is not a difficult task, and we recommend an excellent video to help secure the material.

Those who have more than one renovation experience unanimously claim that there is nothing easier than cutting drywall. However, even such a simple task can baffle a novice builder. The article will tell you how to work with the material correctly and will try to anticipate all the questions of those who got their hands on drywall for the first time.
Specialized publications for builders recommend using tools that cost a lot of money and are primarily useful to professional craftsmen working to order. We’ll talk about improvised means that any man can find at home.
Tape measure, ruler, pencil
Please note that it is recommended to make marks on the plasterboard sheet with a simple pencil. Traces left by a marker or ballpoint pen cannot be hidden by even the most thorough putty.
Construction knife
It can also be replaced by a regular paper knife. Is it true, construction knife With a replaceable double-sided blade, it is more convenient to cut thicker materials. This tool is certainly easy to operate. It will instantly cut the paper layer of plasterboard and deal with the base in no time. However, you will need to tinker to cut an even, neat sheet. Therefore, first we draw with a simple pencil the right lines, we make cuts and only then, when the perimeter of the part is ready, we cut the drywall. The edge of the cut-off part of the plasterboard will have small jagged edges - they will disappear without a trace if you “walk” over them with sandpaper.
Hacksaw
We need a tool for working with metal. It differs from a wood hacksaw in that it has a thinner blade, which will cut the sheet accurately and, most importantly, almost without dust, without deforming its edge. If you have chosen a hacksaw, keep in mind that you cannot work with weight, otherwise you will ruin the material. Place the gypsum board sheet on a stable support, then cut along the pre-drawn line measuredly and slowly so as not to get lost.
Jigsaw
You will not have any difficulties if you purchase high-quality saw blades for tools, preferably for metal work. They are distinguished by a smaller tooth, which will leave a few chips on the end of the drywall sheet. These tools make it easy to cut rounded elements.
Chamfering plane and roughing plane
These tools will be needed at the final stage of working with plasterboard, when you need to give a neat look to its edges.
Good to know - circular saw They don't work with drywall. The tool produces a huge amount of dust, which will greatly clog not only workroom, but also your respiratory organs.
Cutting drywall at home
In a straight line
Using this type of cutting standard sheet drywall attached right size. Place the source on a stable, horizontal surface. After the desired size of the future part is marked on both sides of the gypsum board, take a knife for cutting drywall and use a metal ruler to cut surface layer leaf. For convenience, adjust the knife blade so that it protrudes from the handle to a length that does not greatly exceed the thickness of the plasterboard.
You should not abandon the ruler and cut the material according to the mark drawn with a pencil - this way the cut is unlikely to be even. Run the knife along working line several times to deepen the cut, then the drywall will break exactly where it needs to be.
Now place the sheet edge-on on the support and lightly tap the gypsum board on the side opposite to the cut. Lightly “press” the sheet - as a rule, after several blows the gypsum core breaks along the cut mark. All that remains is to cut the cardboard that connects the two halves of one sheet.
Letter G
This shape is usually given to the material if you need to cover a doorway with plasterboard. We measure and outline the contours of the future part. Then the short part is sawed through with a hacksaw, and the long part is cut with a knife according to the above proposed scheme.
Working with plasterboard fixed to the wall
Although loose drywall is the easiest to cut, sometimes it is necessary to cut and cut off the excess after the sheet is on the frame. This design option is justified by the fact that when covering a window slope or a wall corner with gypsum plasterboard, the edge of the plasterboard sheet, for aesthetic reasons, must be extremely accurately superimposed on the edges of the surface on which it is fixed. Therefore, a plasterboard sheet slightly larger than necessary is fixed to the wall, and only then the extra centimeters are removed.
Make sure that the frame holds the gypsum board firmly. The question of which side to cut the drywall from should not arise in this situation, because the answer suggests itself - cut the side of the sheet that is directly adjacent to the surface to be sheathed. Run the tool along the intended line several times, while slightly “squeezing out” the unnecessary part. Cut the sheet from the reverse side. Let us remind you: to give the sheet on the frame the shape of the letter L, use a hacksaw to cut a line horizontally, and use a knife to saw off a vertical line.
Non-standard cutting and shaped cutting of drywall
Often you have to cut gypsum boards not in a straight line, but as required by the built-in lighting fixtures, sockets or your own imagination in the pursuit of multi-level curved ceiling. Working with indirect drywall pieces requires some skill.
Option 1. To create a perfectly round hole in a sheet of drywall, you can use an electric drill equipped with a special crown attachment. cylindrical. There are attachments of different diameters and applications; they are also called circular saws. Choose one that is designed to work with wood, plywood and drywall.
Option 2. If you don't have a circular saw, no problem. Use a jigsaw: draw a circle of the desired diameter on a sheet of drywall, and drill a hole inside it. Then insert the tool blade and, following the marking outline, cut out round hole. Please note - when working with plasterboard with a jigsaw, use a narrow file with small teeth and take your time when cutting the sheet. The result of unhurried work will be a smooth edge of the part. Operate the jigsaw slowly, but the tool should operate at maximum speed.
Option 3.If you do not have any of the tools listed above, as a last resort, a hole in a sheet of drywall can be made using a special knife for plasterboard and a hammer. To do this:
- mark the worksheet;
- Using good pressure, cut the marked lines with a knife. In this situation, sufficiently cut depth in the sheet is very important;
- place the plasterboard on the surface with a recess so that this recess is located just under the future hole;
- hit the center of the intended hole with a hammer so that the core of the sheet breaks. Try not to overdo it so that a crack does not appear throughout the entire sheet;
- Now break off unnecessary pieces of gypsum board by cutting off the cardboard from the back of the sheet with a knife.
Option 4. The easiest way to cut drywall is with a jigsaw, but if you don’t have one, you can get by with a decent and convenient replacement - a hacksaw for gypsum boards. You can also do it without a hacksaw:
- measure and mark future cuts on the sheet;
- break the cut contour into relatively straight segments and cut them with a special knife, cutting the cardboard and scratching the plaster;
- Break off the resulting sections using the same method described in the previous version of cutting drywall.
It is worth noting that this technology is effective when cutting out large shapes. To create elements with a small radius, use a hacksaw.
How to process a gypsum board part after cutting
The edge of the plasterboard sheet, along which the working tool has just “walked”, does not look entirely aesthetically pleasing. To make it even and smooth, ready for puttying, arm yourself with a plane and remove the chamfer. For this purpose, you can also use with a regular knife. The chamfer is removed to two-thirds of the thickness of the plasterboard, with an angle of 45 degrees.
How to cut a profile for drywall
For this purpose you can use:
- metal scissors;
- jigsaw with metal file;
- hacksaw for metal;
- cutting table or manual machine;
- grinder (only as a last resort - there will be a lot of sparks).
- If possible, cut drywall only on a flat, stable surface, otherwise the material will bend and it will be more difficult to work with.
- Make sure that the drywall sheets are dry - moisture can damage the material.
- It is better to cut large sheets of drywall in several steps.
- When working with a profile for gypsum plasterboard, you don’t have to worry if the cuts don’t turn out neat and even - after installation, the profile will “hide” under a sheet of drywall.
- The frame for gypsum boards can be formed even from small-sized parts metal profile, the most important thing is that these pieces need to be fixed “conscientiously” on the wall.
As you can see, there is nothing complicated in working with gypsum boards. To reinforce the material covered, in particular the question of how to cut drywall, we offer a video:
In this article we will learn how to cut drywall at home. In the previous lesson, we completely made a frame to which you can already attach drywall. But the gypsum boards themselves must first be cut to size. Now we will figure out how this is done.
How and with what to cut drywall at home
The answer to the question of how to cut drywall at home is very simple - for this we need an ordinary sharp painting knife.
It is highly undesirable to use an electric jigsaw to cut gypsum board.
How to cut part of a leaf
So, we place a sheet of drywall with the inner (back) side on the floor (table) or place it upright, with its elbow on the wall, with the inner (back) side facing the wall, the outer (front) side towards you. Using a tape measure and a pencil, mark the distance that needs to be cut on the outer (front) side of the gypsum board. Make two marks on the top and bottom of the sheet with a pencil:
Then we take the rule ( building level, an even strip) apply to the marked marks and mark the line.
It's better to repeat it twice.
After we have cut the paper, we need to refract the sheet along the cut we made. To do this, take a sheet and turn it towards you inside. We clamp one part of the sheet into left hand, the second (cut off) to the right. Moderate movement right hand on yourself (you can also help synchronously with your knee) break the sheet along the cut made:
The sheet broke exactly along the cut line:
The straight cut is ready.
How to make a cutout in a sheet
But what to do if you need to make a cutout in a plasterboard sheet:
or holes, slits, for example, under engineering communications, pipes. After all, if you just run a knife along each of the three sides of this rectangle and then start breaking it out, then nothing will come of it. If we apply force, a fracture will occur that is not at all along the contours we need. So what should we do? Here we need to act differently.
To do this, take a knife for drywall, colloquially “Fox”:
and saw through two sides:
And we simply cut through the third side with a painting knife - only paper:
Lightly hit the spot:
All that remains is to cut the paper on the other side with a knife:
The cutout is ready.
Below is a link to a video about another drywall knife. I haven’t worked with him personally, but judging by the video, he cuts quite interestingly. In principle, if you are working with any tool for the first time, then, of course, you need to adapt:
In this article, we learned how and with what to cut drywall at home.
Drywall is widely used for the manufacture of structures such as ceilings, partitions, and various shelves. But, since gypsum board sheets have standard sizes, they have to be cut.
It’s not difficult to mark a sheet, but how to cut it correctly so as not to spoil it, since the core of the sheet is, after all, gypsum, which is highly fragile? What if you need to make an arch or some other curved structure? Is it possible to bend drywall? And, if so, how?
No need to worry. All these questions have long been answered. It is possible to successfully cut and bend drywall. Our task is to figure out how and how to do this correctly.
Unlike professional builders and repairmen who use a wide variety of tools, at home you have to use improvised means. But the person taking on the repair usually already has everything necessary for the job. Moreover, no special devices are needed.
The following tools can be used to cut plasterboard:
- A ruler, tape measure, and pencil are necessary for accurate measurements and markings of the sheet. To mark small holes you may need a compass, and for large arcs you will need a piece of rope with a pencil attached to one end (an improvised compass that can be used to mark an arc of any radius).
- A construction knife (or a stationery knife, if it is durable). This is a universal tool, and the only replaceable part in it is the blade. Stock up on replacement blades in advance so that you don’t have to go to the store in the middle of work.
- Jigsaw - usually used for cutting wood and wood boards, but it is also suitable for drywall, you just have to install a metal blade (it has smaller teeth and cuts gypsum board better). With a jigsaw you can make not only straight cuts, but also curly ones.
- Planer - it is not used for cutting sheets, but for subsequent processing of their edges. It is necessary to chamfer the cuts - this will allow the joints of the sheets to be properly sealed after installation of the structure.
- Hacksaw for drywall - you can do without it, but with it you can perform some operations faster. This hacksaw resembles a saw knife with a rather narrow blade and jagged edges. The knife blade is made of high-strength steel and is soldered into the handle and allows you to make any cuts (straight and curved) without much effort. The knife is very convenient. If you buy such a tool, you can subsequently use it for cutting small pieces of wood.
- An electric drill or cutter with various attachments will make it easy to cut round holes of various diameters in the slab.
We cut plasterboard in a straight line
Let us immediately note that in order to reduce material waste, you need to take very accurate measurements of the room and use as many whole slabs as possible during installation.
Drywall should only be cut in cases where there are no other options.
Therefore, you need to create a plan in advance for laying out the sheets on the surface, and outline the places where the sheets will be needed non-standard sizes and forms.
Professionals easily cut gypsum boards both on the floor and leaning them against the wall. But if you have not had to do this before, then it is better to place the sheet on the floor face up - this is where the cut will be made.
- sheet markings are usually located on the back side;
- the front side and side edges of the sheets usually have the same color;
- The chemical composition of the front side is different; the facing cardboard contains more cellulose, which reduces the consumption of finishing materials.
The slab is cut as follows:
- Press the ruler firmly against the marked line and run the knife along it several times.
- The knife must be held confidently, avoiding jerks, cutting through the layer of paper and slightly grabbing the plaster. Make sure that the ruler does not move.
- After this, the slab is broken along the cut, bending it in the opposite direction to the cut.
- Then, using a construction knife, you need to cut through the cardboard layer on the other side. If the slab is broken correctly, then there will be no problems at this stage.
- Attach the prepared sheet to the installation site in order to check the accuracy of the cut. If the size is a little large, then the excess can be removed using a rasp (but this will create large number gypsum dust).
- Process the cuts with a plane, removing the chamfer.
How to cut round and rectangular holes
Very often you need to make holes in the sheet for pipes, sockets or switches.
To do this, you need to mark their locations on the sheet using a tape measure.
- Accurately measure the distance of the edges of the hole from both sides of the sheet, as well as from the top and bottom. Draw the outline of the cutout.
- Next, using a drill with a thick drill bit, you need to make 4 holes on the sides of the marked rectangle - the jigsaw file should go through them. They should be located inside the rectangle as close as possible to the cutting lines.
- Insert the saw into each of the holes one by one and cut through the opening. You need to work extremely carefully, strictly along the drawn lines.
- Once you have the hole, check how well the switch or outlet box fits into it.
- If necessary, finish the edges with a rasp.
Round holes:
- For this purpose, you can use a small drill or hacksaw attachment.
- Mark the center of the future hole on the sheet.
- Secure the crown required size in the drill chuck.
- The crown drill must be placed in the center of the hole and drilled, pressing gently on the drill (if you press hard, the nozzle may get stuck in the plaster). Better use it for this average speed tool.
If you don’t have a drill and nozzles, you can make a round hole with a knife, but it’s not so convenient.
Using a knife we make a hole like this:
- Draw the outlines of the future hole on both sides of the sheet (and do not make a mistake).
- Then use a knife to cut through the cardboard layer on both sides.
- After this, you need to lightly tap the plaster with a hammer, knocking it out.
- Check how well the box or pipe fits into the resulting hole.
Any curvilinear figures with smooth lines, cut according to the markings using a jigsaw. If you don’t have one, you can use a hacksaw for metal, but this is very inconvenient.
In order to mount arched structures above doorways or niches, you need to somehow bend the drywall so that it does not break.
For these purposes, plasterboard manufacturers produce special gypsum board (arched) sheets, which are 6.5 mm thick and are easily deformed.
This material is somewhat more expensive than usual. For its installation, special arched profiles, equipped with cutouts on the side walls. Thanks to these cutouts, the profile can be easily bent as required, and then a flexible sheet can be secured in it.
Since the thickness of the flexible sheet is small, to strengthen the structure you need to use two layers of plasterboard: the rough layer is made from a regular sheet, and the front layer is made from an arched one.
But if you were unable to buy plasterboard, then there are ways to bend ordinary wall plasterboard. For different situations used different technologies impact on the leaf.
If you need to get only a slight bend, then you can do it like this:
- The prepared plasterboard blank is moistened with water on one side using a roller or brush.
- It is left for 10-15 minutes so that the water is absorbed into the gypsum layer.
- After this, the sheet is screwed in the intended place. Do this carefully so as not to damage the water-weakened material.
- After the water evaporates, the material regains its original strength and at the same time holds its given shape well.
If the bending radius of the sheet is small enough, then you can bend it like this:
- I process the sheet on one side with a needle roller.
- Then, using a sponge, soak it in water for an hour. Make sure that the paper on the back of the sheet does not get wet, otherwise it may tear when folded.
- Then they carefully bend it using a template and fix the ends of the sheet with clamps.
- The structure is left in this form until completely dry.
If a roller with needles is not at hand, then you can use another option (dry bending):
- Instead, a knife is used to make cuts on the sheet, placing them in a direction perpendicular to the bend line.
- The distance between cuts should be 10-50 mm. The more frequent the cuts, the smaller the bend radius.
- The side on which the cuts are made should always be inside the bend.
Thus, having previously studied all the methods of cutting and bending gypsum boards, choose the most suitable one for yourself and act exactly according to the technology.
During repairs, you have to cut drywall almost every 5-10 minutes. Why? Because a sheet of this material will be at least 2 square meters and without residue it is impossible to mark a partition, ceiling or any other structure. The smaller the structure, the more you will have to cut, and it is not always necessary to cut exactly (corners, uneven walls and no one canceled the ceilings either). What to do? There is only one way out - to learn how to quickly and efficiently cut drywall.
You will need to make not only ruler cuts across the sheet, but also cut triangles, rectangular pieces, ovals or circles (for example, for lighting elements). It is advisable to consider several options for cutting drywall, from a regular stationery knife to electric jigsaw. Now we will look at the simplest and quality methods cutting and processing the edges of drywall.
How to cut drywall with a mounting knife “without noise and dust”
Hand tools performing this action is much easier and faster. The most interesting thing is that the quality of the cut will also be much better if you need to spread the sheet lengthwise or cut an even piece from it. The theory is superfluous here, let's move on to practice and immediately cut the drywall:
- We take the necessary measurements and draw a line. It is advisable to stock up on a marker so that it is convenient to look at the “bold” mark from any side.
2. Along the edge of the line, you can attach a long metal ruler or profile, which is used for fastening drywall.
3. Place the tip of the knife on the edge of the line and begin to draw, applying a pressure of 2-3 kg on the mounting knife for drywall.
4. After the line has been cut, you need to bend the sheet so that the cut area looks like outside. You can put the sheet on the floor, hold the edges with your hands and lightly kick with your knee at the cut site, but with opposite side, the sheet will crack and bend.
5. You will have a corner made of drywall, now you need to take a mounting knife and cut the paper on the other side of the corner. We place the knife on top and pull it all the way to the bottom, getting a high-quality cut.
This method is ideal when cutting ONLY long strips, as you need a lot of pressure to produce a quality fault line. If the lines are made oval or a piece is cut just 5-10 cm from the edge of the sheet, it may break unevenly and the edge may crumble. After the cut, you need to use a drywall plane to “smooth the edges and remove the corner for subsequent plaster (then there will be no “edges”).
It is convenient to cut on a table or on the floor by placing a sheet of drywall on 2 wooden bars next to the cut line. Please note that when drywall is cut, plaster often falls out, so it is better to put something under it if the cut is on a clean surface.
Features of cutting drywall with a hacksaw - an option for hard workers
It is better to use a hacksaw if necessary figure cutting when you need to cut drywall in a semicircle or make holes inside it different shapes. By using assembly knife this is impossible to do, at least not with good quality. Now let's look at how to cut a sheet of drywall with a hacksaw and make holes inside it.
STEP 1: marking. You need to draw a sheet of drywall on the back side, make holes in the corners of such a size that a hacksaw blade can fit into them (you can use a sharp knife or drill). 
STEP 2: sawing. Insert a drywall tool (hacksaw) into the hole and cut to another extreme point, turns are best avoided. 
STEP 3: when the cut is made along all the drawn sides, and the figure inside the sheet “fell out,” you can process the edges. Use a plane or a file if the hole is very small and another tool cannot fit there. 
We looked at how to cut drywall and cut out the hole you need in it. rectangular shape, but there is an even more difficult task - non-standard or oval figures inside the sheet. Here you need to work with thin blades on a hacksaw, which will be convenient to turn when making internal cuts. In such cases, it is better to abandon the hacksaw and use a jigsaw, since the quality of the edges of the cut hole inside will be much higher.
Cutting drywall with a jigsaw - an option for the lazy
If you don’t know how to cut drywall at home and are afraid to experiment, then it’s better to entrust the processing of the material electric tool. A jigsaw is the optimal tool for cutting drywall because it allows you to make a sheet of any shape and can make holes inside a sheet of drywall. The curved lines will be as precise as possible, and the edge will be much easier to process using a drywall plane.
Let's consider step by step instructions How to properly cut drywall using a jigsaw:
1. Draw a line along which it will be necessary to cut the material. It is better to use a black marker so that it is clearly visible. 
2. We install a sheet of drywall on several bricks or stools so that so that there are no objects under the cutting line(they may get caught by the saw). The sheet should lie balanced and not be tense at the cutting points - the quality of the cut will improve significantly. 
3. Place the jigsaw at the beginning of the line, turn on the laser sight (if the tool has one) and guide it exactly along the desired path. Or we bring the drywall to a stand with a jigsaw. 
4. We demolish the edges at 45 degrees to plaster the surface. You can even do it with sandpaper, if the processing area is not too large. 
5. If you don’t have a plane or you can’t get the corners right, then a drywall cutter will be a useful tool. It can be put on a screwdriver or drill, the cone can be placed between the sheets and passed along the joint. Cutting knives They will remove the edges of each sheet at the same angle - very convenient for large volumes of work, where you need to process many sheets quickly and efficiently. 
Perhaps you wanted to ask how to cut drywall L-shaped under a door or window opening? Here universal tool can't be found you need to use both a hacksaw and a jigsaw, because with a jigsaw or hacksaw alone you cannot get internal corner 90 degrees.
There will be a jigsaw the perfect tool for you if you don’t have anything to cut the profile for drywall, since it is also suitable for metal. You need to buy several files “for all occasions” and you will be able to cut not only drywall, but also metal, wood, stone and other materials. Now let's watch a video of cutting drywall with a painting knife without noise and dust:
Successful repairs and pleasant DIY work!
