How to cut a corner of 45 on the corner

Tools for work

To fix the plastic, you need a glue gun. It allows the precise application of the compound used. It is also necessary to stock up:

  • With a hacksaw or metal scissors;
  • A box cutter;
  • With a metal angle;
  • A tape measure, a pencil;
  • with painter’s tape;
  • with an adhesive compound.

To get the profiles of the desired size and shape, you can use a power drill. However, if this tool is not available, that’s okay.

A few words about tools and materials

Floor skirting boards are now made of wood or polyvinyl chloride (PVC), simply put, plastic. Ceiling fillets have a slightly longer list:

The range of ceiling skirting boards is much wider than the flooring direction.

  • Polyurethane. these baseboards have good elasticity and can envelop radial and other curvilinear surfaces, but under clear corners, they must in any case be trimmed;
  • Foam plinths. the easiest budget option, the price of foam plinths is low and they are very easy to cut;
  • PVC. the same principle as the floor plinths, but the range is much wider;
  • Wooden. similar to the floor, except there are also wide models;
  • Gypsum. with the advent of polyurethane and foam plastic, gypsum ceiling ties have receded into the background, firstly, they are heavy, and secondly, fragile. But to be fair to mention them is worth.

As it is impossible to cut properly a ceiling molding and its floor counterpart without a good tool, we’ll dwell on this question in a bit more detail.

The best, almost perfect tool for trimming any skirting board or anything else is a sliding compound mitre saw with a pivoting frame. The high-speed disc makes smooth and precise cuts, and the bed in these units rotates to any angle. The only problem is the serious price of this tool.

Trimmer saw is almost ideal for trimming baseboards and not only them.

One of the best hand tools for making precise cuts in small wood is said to be the barrel saw. This is true in principle, but I will tell you honestly, it is not easy to find a really good saw, even with the current range. If you do decide to buy such a tool, then buy a saw with a fine tooth.

Sharpie saw is handy when working with a jigsaw.

Theoretically the foam plastic and polyurethane can be cut with any sharp and strong knife. But you need a steady hand and at least a little experience in cutting foam. Plus, wide skirting boards are hard to cut with a knife.

Without experience it is very problematic to make a clean cut with a hacksaw.

Personally, if I don’t have a trimmer I only use a metal hacksaw. It is suitable for cutting absolutely any material, from Styrofoam to wood. By the way, often ask the question, what to cut a plastic skirting board for the floor, so here. take a hacksaw for metal and definitely will not make a mistake.

For trimming baseboards, a metal hacksaw is considered one of the best tools.

How to saw a 45 angle without a jigsaw

Often during repairs, you may encounter a situation where it is necessary to saw off a piece from the part, at an angle of strictly 45 degrees. Usually it is needed to join two parts at right angles, 90 degrees, such as: door trim, baseboard, furniture and more. An experienced craftsman, professionally engaged in repair work, can often do without special devices, and practically by eye is able to even and clearly cut the necessary part. But if you are a novice repairman, and you want to do the job as efficiently as possible, without damaging expensive parts, then you just need to buy a plier. a special device that allows without any tricks to saw off the material at a given angle.

To work you need to have: a plane, a hacksaw, a protractor with a pencil, a workpiece made of wood, an electric screwdriver with screws or a screw clamp.

What is it needed for?

Basically, sawing the corner edge of the tiles at 45 degrees is carried out in the following cases:

  • to match the inner and outer corners of rectangular tiles when they are docked in the process of laying;
  • For the formation of a beautiful edge in the form of a bevel;
  • When laying diagonal tiles.

Trimming the edge part of tile products at a special angular slope makes it possible to forget about the use of applied corners forever.

The electric machine

The main advantage of this tile cutter is a clear and high-quality cut on tiles, which is carried out in two directions: an ordinary straight cut and a special cut at an angle of 45 degrees. Thanks to the rotation of the cutting wheel at a certain angle to the cut part of the tile is easy to make the cut, starting from 0 and up to 45 degrees. An electric tile cutting machine can have a water feed, so that less dust is released, or it can have a regular design. However, both variations of devices provide the same quality of work and guarantee the cutting of a large volume of tiles in a short period of time.

In the case of concave tile cutting, the electric tile cutter does not follow the concave deflection of the product. Therefore, only the back side can be cut, so as not to damage the enamel on the front part. This applies in particular to porcelain stoneware.

  • a special masking tape;
  • a simple pencil;
  • a small ruler;
  • A tile-cutting machine;
  • angle grinder with adjustable speed.

On the part of the tile where the cut will take place, it is necessary to glue a masking tape. Use a pencil and ruler to make the necessary marks. Then place the tile on a specific section of the appliance at a 45 degree angle. On the principle of a circular saw, a diamond band is used to cut the tiles. Some models supply water during the cut, which protects the tile from melting and washes away the dust.


If the glaze on the outside of the tile is damaged, the cut will be ugly with cracks and scored edges, which when laid side by side will have a sloppy appearance. Therefore, working with an electric tile cutter, you need to carefully remove only the clay layer.

Professional secrets of experienced tilers:

  • With the help of a tile cutter it is necessary to achieve an even cut;
  • then form the necessary angle on the back side of the product;
  • The glaze, which was caught in the working process, is rubbed out with sandpaper.

Cutting at a 45 degree angle

Usually, in order to turn the pipe by 45 degrees use fittings, bends with an angle of rotation of 45 degrees, made of the same material as the pipe itself, if the pipes are steel, then the bends are welded from steel. For HDPE pipes, there are electric-welded or cast 45 degree bends (note that compression fittings with such an angle of rotation in Russia is almost impossible to find).

But if you still need to cut a pipe with a circular cross section made of steel or various types of plastic, you will need a template for cutting pipes at an angle, the shape of which is calculated by hand or machine. The task is greatly simplified if the angle of forty-five degrees to cut a metal profile with a square cross-section.

For cutting quickly you can use an ordinary sheet of paper folded diagonally, with which to mark the surface for the future cut. Using folded paper, proceed as follows

  • Conduct on the straight surface of the profile in the place where the cut is made, strictly perpendicular to the line;
  • lay a sheet of paper folded diagonally to the side with a sharp end to a mowing line so that the upper edge of the paper triangle is flush with the upper side of the metal profile.
  • Hold the line with a pencil on the side of the sheet at an angle of 45 degrees, then the paper corner is placed on the other side and trace it with a pencil (better to use a thin marker).

For sawing can be used angle grinder with a disc for metal, conducting a thin line at the beginning of the marking, then gradually deepening it to complete separation of the edges.

When working with the angle grinder must consider the following factor when fully cutting edges of the disk can be damaged on a sharp corner, which will lead to its failure, and in the absence of protection on the angle grinder even to injury to the employee. Therefore, it is desirable not to cut the corner edges to the end, but to leave a narrow groove and then break up, sanding subsequently the ledge.

Making a template for trimming metal profile

If you need to cut a large number of pipes, you can make a template from metal profile of a larger diameter on a paper sheet by the above method. Angle of inclination is checked with a protractor or a construction angle, in this case the two edges of the cut parts of the template are connected.

When working on the part to be cut, the template is put in the right place and pressed tightly, the marking is applied with a sharpened scribe when outlining the template contour. The part is cut in several steps with a gradual deepening of the groove.

The chisel for cutting pipes with their own hands

Using the template is not too convenient you have to make a cut on the line, holding the angle grinder by weight, which leads to large errors. If you have a welder, you can make a simple jig to guide the disc angle grinder that does not let him go sideways.

For this purpose, use a previously made template, drill a hole in the side of which and weld a nut. When working, the homemade saw blade is put on the profile, a bolt is screwed into its nut and the device is pressed against the profile surface. Use an angle grinder with a metal disk to make a cut, pressing the disk lightly against the side surface of the device. It is clear that with prolonged work, the edges in the wire cutter gradually wear down, and although the process occurs simultaneously on all edges, some inaccuracies will appear over time. That’s why it is better to make the device from hard, wear-resistant metal to increase its life and to obtain a more accurate tool.

How and what to cut a plastic plinth

All of the above applies to skirting boards Wood-fibre board and wood. It is not a problem to cut them with an ordinary hacksaw. It is desirable to take a blade on metal, as it has a finer tooth and a cut turns out more even, it is less necessary to work with sandpaper. This is not the case with plastic when trying to cut a piece, some thin-walled skirting boards crumble and break.

Plastic is not easy to cut because of its thin walls

For cutting normal quality plastic skirting boards you can use:

  • Metal saw.
  • An angle grinder (angle grinder) with a diamond disc.
  • A turner with a trimmer saw. Before starting to cut, break up the blade and only then start cutting.
  • A jigsaw and fine-toothed saw. Here you need to try to pick up the speed and the saw.
  • A sharp knife.
  • Metal scissors. Anyway it’s not hard to make straight cuts with them.

Only personal experience will help to determine, what is more convenient for you to cut a plastic skirting board. If you have a coping saw, try it. It is not a problem to try a couple of times with an angle grinder with a diamond disk. If that does not cut it, try a hacksaw, jigsaw, or utility knife. There are, of course, special scissors for plastic, but for a single use they are too expensive to buy.

Accessories for design of corners and joints of PVC skirting boards

In plastic skirting boards, you can decorate the corners and joints with special fittings. There are exterior and interior corners, plugs and connectors. In principle, they allow you to assemble the desired configuration. Each manufacturer makes its own fittings for its own profile, colors. But the principle of their use is the same.

How to make the corners of a plastic baseboard

The first rule is to make all cuts straight. Strictly perpendicular. Marks in the corners put indented 1-1,5 mm from the corner. The fact is that the hardware for rigidity has its own crosspieces. Here for them and it is necessary to indent a couple of millimeters, but no more. Otherwise there will be a gap or the skirting boards will pop out of these corners.

Here’s what you get as a result of the assembly

It must be said that the look of plastic corners is not to everyone’s liking. You can make a corner on a PVC skirting board exactly as described for wood or Fiberboard. The only problem is that you have to be more careful with the plastic, it breaks from the excessive force. There is one trick before you cut a plastic baseboard, add some assembly foam on the back side and wait for the beginning of polymerization. It will be stiffer, easier to cut, less deformation. If the foam later gets in the way, it is not a problem to remove it, and cutting is indeed easier.

How to make a 45 degree angle. How to cut a corner of 45 degrees

During repairs or construction is not uncommon situation where you need to make the joint 2 parts so that it fits perfectly into the corner of the room. If in this case it is necessary to cut a corner in 45?, Do one of the following. You will need

  • – ruler;
  • – Pencil, pen, marker;
  • – piece of paper;
  • – protractor;
  • – ruler;
  • – a knife, scissors, jigsaw, or other cutting tools.


If the surface of the material is quite extensive and allows you to make marks, draw one of the cutting lines with a ruler. After that, draw a perpendicular to this cut line, using an angle piece or any object with even edges, say, a sheet of paper or a book. 2. On the whole side of the angle, use a ruler to mark equal lengths, say, 10 cm. Measure the distance between the obtained points and divide it in half. Combine this point with the vertex of a right angle. You have obtained an angle of 45?, Now cut the material along the drawn lines with scissors, a knife, a jigsaw or other tools. 3. Mark one of the lines of the cut, take a protractor and apply to the mowing line. Find the 45 mark on the scale? and join this point with the center of the protractor. Along the marked lines cut the material with the available tools. 4. Paper, film, foil or other easily bendable material cut in a further way: find or draw a right angle (for a sheet of paper is any of its corners). Fold the sheet so that the adjacent sides overlap. Cut the sheet along the mowing line of the fold. 5. If you need to cut a 45-degree angle several times, say, when fitting a baseboard, make a pattern. To do this, take heavy cardboard, draw a square on it and cut it diagonally. 6. To cut materials at a 45° angle? In a large volume, purchase a plier, this tool is easily available at any construction store. Put a skirting board or rail inside as will be placed in the space, and cut it with a knife, jigsaw or other tool.

Using a diecutter to cut casings

Such a device as a plier is very convenient to use, in addition, it is inexpensive. Therefore, if possible, it is better to buy it in advance, it will not take up much space in the closet. Most often the wire is sold together with a fine hacksaw, which is easier to cut casings. If you do not have one, you should not use a standard wide-tipped hacksaw for cutting. Best suited for this purpose hacksaw for metal, with its help the cut will be more accurate.

How to evenly cut the corner of the ceiling plinth with it?

Pliers are called uncomplicated tools used by carpenters. It can be used to cut any workpiece at the desired angle.

It is usually a wooden, metal or plastic tray, which are made to cut at an angle of 45 ° and 90 ° special vertical slots.

There are complicated designs, which in addition to the named angles also have a hole to make a 60-degree cut.

For professional applications, a special mitre saw is available. Its swivel mechanism allows you to fix the cutting blade in relation to the workpiece at any given angle.

Inner corner

The prepared plinth is applied to the ceiling, the required length is deferred.

Then this very slat is inserted into the jig exactly as it will be positioned on the ceiling. It must be pressed against the far wall of the device. In this position, the plinth is held by the left hand.

The blade of the hacksaw should be in such a position that its angle is 45 degrees, and the handle is as close to the hand. Trying to avoid exerting pressure on the saw, we carefully cut the workpiece.

Further it is necessary to cut a mating strip from the skirting board. It is also placed at the far wall of the tool, held and pressed, this time, with the right hand.

Similar to the previous procedure is the position of the hacksaw. its handle is close to the hand at an angle of 45 degrees. The skirting board is cut.

Then the finished, already cut slats are docked. the accuracy of the fit is checked. It is believed that for better orientation, in the manufacture of the inside corner, cutting is better to begin with the front of the product. The places of cuts are usually adjusted by using a file.

Outside corner

The right thing to do, in order to observe more accurately the dimensions, first begin to mark the inner corner, and only after that move on to the outer.

Otherwise it could happen that the entire length of the plank is insufficient.


The strip is attached to the ceiling, to the size made marks. Holding it with your left hand, hold it against the closest wall with the hacksaw handle close to your hand. The workpiece is cut.

Throttle plate is pressed against the nearest wall with the right hand. The blade of the hacksaw should be at a 45° angle, with the handle of the tool close to the hand of the craftsman. A piece of the billet is cut, the corner is neatly docked.

Such machining of parts with the help of mash is good if the angle between the walls is flat and straight (90 °).

If its performance leaves much to be desired, it is worth using another method.

Marking on the ceiling

In all other respects, you can use this method to mark the angle of the cut even more accurately than other methods.

When the skirting board is attached to the proposed place of installation, all size deviations and inaccuracies are noticeable and are immediately taken into account.

Trimming the corner

First you need to take a pair of blanks, then cut them at right angles. With the end of the plank against a perpendicular wall, we attach one plank. We draw a fishing line on the ceiling along the contour of the skirting board. We remove the first lath, and then, in the same way, with the end pointing to the wall, we put a counter lath. Exactly the same way we mark along the contour of the fishing line.

The intersection point of the two separate lines is the mark at which the workpiece is cut. Each skirting board is placed against the surface again and the point of the future cut is marked on both of them. From the found point to the other edge of the skirting board we draw the fishing line. Baseboards are cut to the previously made marks, neatly connect, and place in their place of installation.

This method allows you to more accurately process inside corners.

How to make a template of the chisel with their own hands

If you do not have a jigsaw, you do not need to buy a tool for one-time use. A template with similar functions can be made yourself.

To do this, the necessary corners of the cut are drawn on wood, paper or cardboard.

Then you need to draw a pair of parallel lines, find the center, and then use a protractor to measure corners of any given size.

This method is particularly convenient because, using it, you can set aside an angle of any magnitude, even larger than a straight angle.

The method of processing the skirting workpiece with a homemade tool practically does not differ from the work with the original. The bar is pressed against one of the parallels, then the hacksaw is set at the desired angle, and cut off.

Remember that before you cut the corners of the workpiece, be sure to check the size of the angle between the walls! For this use protractor and angle.
