A little about the tool
To correctly cut a drywall sheet, some special tools will not be needed. All of them are in the set of each repairman and builder even at an amateur level. The work will need:
- Well -groomed pencil, which are marking.
- Roulette, at least three meters long.
- Metal line or part of the profile.
- Tool for cutting drywall: knife (stationery or universal), hacksaw, electrician, circular saw.
- Pittle rubbish - designed to process the cut edges. It is better not to try to replace it with a file or use a kitchen grater. The quality will not be, and its price is low, you can afford to buy.
Types of cutter's cuts
Direct - This section reduces the standard sheet to the necessary dimensions.
The mechanism of action:
- note on both sides the size that is necessary;
- apply a ruler or profile and draw a knife along the upper layer of the sheet. Be sure to use a ruler for this. If you just draw a line with a pencil, and you will draw a knife on top of it, then the incision will not be even. Run along the upper layer several times, then you can be sure that the sheet will break through this line;
- put the drywall on the rib and on the back, where there is no incision, knock on it without zeal with a knee. After a couple of strokes, the sheet should break along the line of the cut;
- cut the cardboard along the line, which connects two parts and we can assume that the work is done.
Double -sided neckline - Such cutouts are made when you need to insert a window, door or beam in the design made of drywall.
Mechanism of work:
- make a cutout of the required shape on one side of drywall, usually it is a rectangle, and one side is cut with a hacksaw, and the second with a knife;
- break the sheet;
- cut the cardboard that holds drywall;
- treat the cut place with a pendant shirt. 3. Round holes - Designed for installation of lamps. They are performed in two ways:
- with the help of a nozzle, which also cut holes for locks on the door. It is dressed on a drill and cut a hole with it;
- cut the circle with a knife with a knife and gently knock it out with a hammer. With a nozzle, the circle will turn out more beautifully, but this option also has a place to be. An uneven neckline - Such cutouts are usually made in bathrooms and bathrooms, where it is necessary to carry out a water supply or sewer through a drywall. The most difficult thing in this process is to correctly calculate the future neckline. Before cutting out, you need to double -check your tags several times, because it is at this step that many sheets of drywall are spoiled. Since, if the hole is more than you need, it will not be possible to attach the sheet to the frame, there will be no place for screws. And if the size is smaller, then you will have to spend a lot of time to fit as it should. As a rule, all the lines that go unevenly are a combination of a semicircle with straight lines. Where the sections are straight, it will be better to use a hacksaw, and where a semicircle or bend, then cut out with a knife.
Construction or stationery knife
A knife for cutting drywall can be both ordinary stationery and a special mounting. They differ in massiveness and in that the clerical usually cut paper, and more solid materials are more solid.
The advantages of using a knife in halzing cardboard cutting:
- The knife easily cuts out the base of the drywall, and the layer of paper is cut into one touch.

Their shortcomings, the main one - it is difficult to cut off the flat line on drywall, first you will have to draw a line on the sheet and only then, after highlighting a clear perimeter, can be cut.
Work order:
- The cut line is planned on the drywall sheet.
- Apply a ruler or bar to the cut line.
- Gently cut part of the sheet and core along the drawn by the border.
- If you cut off on the table, then push the sheet of drywall so that it sagging a couple of centimeters beyond the cut.

Cutting plasterboard with a hacksaw for metal
For cutting drywall, it is best to take a hacksaw precisely on metal, and not on wood. Since in the first case, the blade cuts drywall more accurately. When cutting sheets of dust, there are no dust, and those particles of drywall that are crumbling are well collected by a vacuum cleaner. Cutting rectangular holes well with a hacksaw.
Work order:
- Mark all four sides of the holes with a pencil.
- In each corner, make holes with a drill. At the same time, make sure that the holes are drilled so that they are located inside the details, touch the drawn line, but do not cross it. And the diameter of the drilled hole should be such that a hacksaw can easily pass.
- Cut all the sides of the holes with a hacksaw, while ensuring that the hacksaw and sheet are perpendicular to each other, so the edges will remain more neat.
- If the dimensions of the hole allow you to walk around the edges of the shirt, then use it, if not, then the file will become an alternative.
Hypsum plasterboard cutting with an electric jigsaw
The electrolobian for cutting drywall, mainly, are used by builders. The most important thing that is worth paying attention to is the quality of the file. It is necessary to take files for metal, because due to the fact that their teeth are small, then there will be smaller chips on the end. Electrician is more advantages than other tools:
- This electric tool is of greater performance. So, if only four sheets can be cut with a knife per hour, then a jigsaw for the same amount of time can be done several times more than the work.
- No need to make a lot of physical effort. From all the work that you have to do with your own hands is to hold a drywall sheet.
- The power of the tool allows you to saw several layers of drywall at once.
- Circular parts are well obtained. And if compared with previous tools, then the rounded part cannot be sawn off in general with a hacksaw, and if you do it with a knife, then you need to additionally process the edges.
- After cutting with an electric jigsaw, the edges of the shirt do not need to be processed, they will already be perfectly even.
Among the shortcomings, one can distinguish that it is expensive compared to other tools, and the fact that the jigsaw needs electric power, and the generators are not at all construction sites, so people have to use a manual tool.
Work order:
- Mark a sheet of drywall.
- Put the sheet in two chairs so that the cut line between them in the free space is.
- Install an electrician at the beginning of the line and slowly draw throughout the figure.
- Drive the holes inside the part with a drill. The hole should touch the circle from the inside.
- Lower the electric device into the hole and cut the necessary figure.
Circular saw: use?
Despite the fact that many builders do not advise using a circular saw for cutting drywall, in principle, there is no ban on this tool. Circular saw is a fairly productive tool. It is easy to work with her, but she has one significant drawback, which makes many refuse her - this is dust. In a matter of minutes after you begin to cut the layers of drywall with a saw, everything around is tamed with dust from gypsum. Therefore, when working with it, you must definitely use the mask and glasses. Otherwise, dust will fall into the lungs and there will settle, which will lead to the development of diseases.
