How to cut with a circular saw at 45 degrees

When buying, be sure to pay attention to such an indicator as the depth of the saw

Note: The cutting depth of circular saws ranges from 30 to 130 mm..

You need to know with what thickness boards you have to work with. The choice of saw blade is also very important. For a neat cut, a disc with a larger number of teeth is suitable. If the blade has sparse teeth, the cut will be faster, but the cut will be rougher..

Cuts with such a saw, as a rule, are smooth and there are practically no chips

Tips for beginners when choosing

Precise cutting template

How to cut smoothly? A certain device is made with a small allowance, after pressing the circular to the stop, we saw off the edge of the base to the desired length. Along the sawn edge, the line for cutting with a circular saw is determined.

A mark is placed on the board in the place where the saw was made Pressing the lower stop of the device to the board, the edge is leveled. Because the saw first passes through the attachment, the cutting of the boards is more accurate..

How to learn to cut at a 45 degree angle with a circular saw.

Probably everyone who makes repairs on their own has come across the fact that you need to saw a board or pipe, cut the plinth. In practice, it turns out to be quite simple..

The most convenient tool for this is a circular saw. In this article, we’ll show you how to learn to cut at a forty-five degree angle with a circular saw – tips for beginners.

A circular saw is more efficient than some other electric tools.

It is important, when purchasing, pay attention to the characteristics of the saw

So, for example, most of the models can be adjusted from 90 to 45 degrees, which makes it possible to cut beveled ends, hipped rafters and cut at an angle of forty-five degrees. Almost all saws have a screw with a lever to loosen the bolt that holds the blade at the correct angle for cutting. Some models have a scale that shows the angle of inclination of the blade from 0 to 45 degrees.

Saw types

There are several types of saws that differ in the field of application and characteristics. The main use of a circular saw is still sawing boards..

Let’s get acquainted with some types of circular saws:

  • Trim saws 12.5 cm with fine-toothed blades. As a rule, the blade is located on the left side of the motor to make it easier to observe how the blade is going. There is a 120V AC voltage model, as well as a battery that works with different DC voltages;
  • saws about 17 cm for cutting to length of lumber. Works well with slitting, cut plywood, composite material;
  • saws with a size of 19 cm or skill saws. They cut materials with a thickness of more than 5.5 cm. Designed for sawing materials of supporting structures, as well as for longitudinal cutting. Comes with a set of blades that can be used to cut composite material, concrete, metal, etc .;
  • saws of 20 and 25.5 cm, designed for cutting large sawn timber up to 10 cm in length. These tools are heavier and larger in size. They are mainly used on an industrial scale;
  • 22 cm models with worm drive, gearbox and motor. They are used more often for longitudinal cutting of lumber or for cutting plywood sheets for formwork. Here the blade is located on the left side of the motor..

Circular saw tips

If, when sawing, the edges turned out to be torn with chips, you need to do the following:

  • We take a small sheet of hardboard 6mm.
  • We glue this sheet to the base with tape.
  • With the switched on saw, we immerse the disk in hardboard to obtain a cut with a zero clearance.

How to cut at a 45 degree angle?

This angle is found in the manufacture of various products. Let’s start cutting off. First, the saw foot is shifted ninety degrees. Depending on the model, there is a bolt with a red handle on the side of the sole that needs to be loosened.

Then the sole is displaced at an angle of forty-five degrees and fix the bolt back. We take a piece of chipboard as a blank. We fix it with the help of clamps on the table top so that the part that we will cut off goes beyond the table.

After that, the ruler is set. It is usually included with a circular saw. The saw has 2 marks zero and 45. We will cut off 30 millimeters by aligning the three on the ruler with the mark forty-five on the sole. Then you need to tighten the bolt that fixes the ruler.

Next, the sole must be positioned so that the ruler rested against the edge of the workpiece. The saw starts and after it is fully unwound, tightly pressing the ruler to the edge of the workpiece, they move in the forward direction.

If the angle is not right

Unfortunately, in some cases the angle between the walls in the room is not straight, but sharp, or, conversely, obtuse. This is due to structural defects that have arisen through the fault of non-professional builders, the architect’s idea or the result of soil subsidence some time after the construction of the building. This is especially common in village houses and summer cottages..

House plan with sharp and outer corners

No miter box or a drawing replacing it will help in this case, and you will have to do the markup in place.

circular, degrees
  • Attach the workpiece to one of the walls so that it rests against the other wall with its end.
  • Run the line on the ceiling along the workpiece.
  • Perform the same operation against another wall..
  • At the intersection of the two lines, put a mark on the workpiece itself.
  • Draw the line from the mark to the corner of the workpiece and cut along it.
  • Do the same with the workpiece, which you will attach to another wall..
  • Glue both blanks; they will come together tightly.

Sawing wood at an angle

Sawing wood at an angle is more difficult than ripping or cross-cutting wood.

circular, degrees

All the variety of sawing wood at an angle can be divided into three main types. A 45-degree cut runs across the face of the board. The slanted cut runs across the edge of the board between opposite surfaces. A complex cut is a combination of the first two types. When sawing boards at an angle, the usual joinery tools are cross and circular saws, although a special technology is used. For example, using a hand saw, you can secure the rail and workpiece to prevent the saw from sliding along the board. When starting to work with a circular saw, the hood must be raised: since the base can only be tilted 45 degrees, an additional corner will need to be cut. When doing fine work with a miter box and a saw, you will need to position the tree on the edge.

Particular attention should be paid to the accuracy of the work, otherwise the parts will not fit together well. For example, you can stack two planks and draw the line where they intersect. In other cases, the angle at which the cut is made is known in advance (say 45 degrees when making architraves). Quite often, tools such as a protractor and a mala are used. The last device is a wooden handle bolted to a metal plate (Figure below).

In the simplest cases, set the required angle on the bevel and, attaching it to the board, draw a line. The circular saw is installed in the same way..

Determination of the angle when sawing wood at an angle.

Having released the clamping nut, attach the bevel to the corner that you want to transfer to the workpiece (Fig. Top left); tighten the nut. Pressing the handle firmly against the edge of the board, draw a line (fig. Top right).

Using a hand saw.

Using a hand and circular saw

Place a 50×100 mm block along the mowing line and secure with clamps. After sawing the recess, check whether the blade follows the drawn mowing line, if not, then start sawing again (Fig. Top left).

Using a circular saw when cutting wood at an angle.

Nail the guide to the board as shown in the picture above on the right. Place the saw base along the rail. Before turning on, raise the guard until you have cut through the edge of the board. If the saw deviates from the mowing line, do not try to fix anything along the way: it is better to start sawing again (fig. Top right).

Performing difficult circular sawing jobs when cutting wood at an angle.

Performing difficult work with a circular saw

Installing the disc. If the angle of inclination exceeds 45 °, then install the bevel as shown in the figure on the left. The saw blade is set to the maximum depth. Holding the grip handle at the bottom of the saw base, release the goniometer nut, fold back the cover and tilt the base so that the metal plate of the gouge lies along the blade. Tighten the goniometer nut. Draw a line across the board and line up the saw blade with the blade using the base guide. Start work by lifting the cowl. If the angle of inclination is less than 45 °, then use a protractor to correctly install the handle and bevel plate. Further follow the above method.

Complex cut. If you use a hand saw, this job requires two sequential operations – miter sawing and bevel sawing. If you use a circular saw, one operation will be enough. Mark the corner first, then tilt the disc.

How to cut a board at an angle or slope.

Position the saw at the desired angle using the scale. Lay the board flat and secure with clamps. Lower the blade and cut the workpiece. If you want to cut the board at an angle, then place it on the edge and repeat the same steps..

Sawing at an angle less than 45 degrees.

Draw the cutting line and place the board in the miter box. Position the saw as close to the line as possible, then slide the plank to align the blade with the line.

Position the piece of wood as shown in the figure below on the right and secure it with a clamp. Saw the board, making sure that the cut follows the mowing line exactly.

How is the miter box used?

Circular Saw Cut 45 Degree Angle for Repairing a Picnic Table

What is an electric grinder.

An electric miter box is a device that consists of a conventional miter box and a radial saw. It allows you to quickly cut at an angle (tilt) a large number of workpieces. The electric wort disk rotates away from the worker, pressing the workpiece against the table and stop. The device has a mechanism for measuring the angle and a pointer with a scale that determines the rotation. The steering angle is 48 degrees to the right or left of the center line marked as 0 degrees. Most models automatically lock the dial to 0; 22.5; 45 degrees. The saw handle, equipped with a trigger, allows you to control the vertical movement of the blade. When the blade plunges into the wood, the saw cover is lifted and the sawdust is removed through a special tube. The whole rig is bolted to the table.

The procedure for working with the electric machine.

Working with an electric driver

Turn the saw 45 to the right of the zero mark and secure it in this position. Install the board like this. so that the plane of the blade is in line with the cutting line. Hold the workpiece with one hand, turn on the saw with the other and lower the blade down. After sawing the board, turn off the unit and raise the saw; wait for the disk to stop completely.

Keep your hands away from the rotating blade and always check the movement of the saw along the line. Do not try to cut the workpiece into pieces of less than 200 mm, as it may break out of your hands..

Sometimes you need to trim a particular part or product at a certain angle. As a rule, you need to trim baguettes, fillets, platbands, baseboards and other similar interior elements at an angle of 45 degrees. Anyone can cope with this task. The main thing is not to rush, not to be nervous and everything will work out..

Buy ready-made corner pieces

For example, with regard to baguette or fillets, special corner elements are sold for them, which perfectly fit into the corner and do not need to be trimmed. You just need to glue them in place and press them well..

Trimming parts at an angle using a protractor

You can trim the part at an angle using a protractor. This is a measuring tool that is easy to use, and which is designed specifically to measure angles or make the necessary markings on certain parts. The protractor is applied to the part, the angle is marked and the markings are made with a pencil. Using this marking, it will not be difficult to cut the workpiece at the desired angle..

Using templates

If there is no protractor, miter box or ready-made corner pieces available, you will have to look for a suitable template. Of course, the template must have the correct angle. It is applied to the workpiece and the workpiece is marked with a pencil. This is one of the easiest ways to achieve the desired result..

How to make a miter box at home?

If the above methods are not to your liking, you can make a miter box at home on your own. A miter box is a device that resembles a tray in its shape, which has a U-shape.

It is equipped with saw slots for cutting material at a certain angle. The dimensions of the parts are not very important, but the wider our homemade device is, the wider and more accurate we can cut wide slats.

Important:
Everything needs to be done wisely, you should not overdo it either, because if the width of the miter box exceeds half the width of the hacksaw, it will be inconvenient to saw.

You can do the markup using the methods described above, then use small pieces of plywood and a hacksaw. And in order to hold everything together, you can use self-tapping screws or even super glue. However, all this is more complicated and will take much more time, although it will provide the most accurate result (of course, if you do everything right).

However, if for some reason a situation arises that it is impossible to get the tool in the shortest possible time, you can use improvised tools, such as a ruler, protractor or even tiles, with which it is easy to create a template with the necessary markings or even completely recreate a miter box at home.

Today it is impossible to imagine the interior of a residential building or apartment without ceiling plinths. The skirting board covers the irregularities of the suspended ceiling or wallpaper, cracks and imperfections in the walls, and gives the interior completeness. But how to make the skirting board perfectly fit in the most important place – in the corner? There are several ways.

How to cut a skirting board without a miter box?

The easiest way is to draw the future cut line on paper (cardboard, wallpaper), and then, attaching the baseboard blank to it, cut.

To do this, you first need to attach the skirting board blank to the paper and draw two parallel mowing lines, which will indicate the sides of the skirting board. Then, using a protractor, you will have to measure 45 degrees and draw the line of the future cut. Then the drawing is used in the same way as the miter box: a blank is placed on it and the excess is sawn off along the mowing line.

How to cut the corners of a skirting board without a miter box

The disadvantage of this method is that the saw will have to be held on weight, focusing on the drawing, and not inserted into a previously prepared slot.

Using a miter box

Factory made miter box

The miter box has a recess for a cut-off board or plinth and saw slots at an angle of 45 and 90 degrees. You will need to cut the skirting board at a 45 degree angle.

To cut the skirting board with this device, you need to follow these steps.

  • We apply the plinth to the future attachment point.
  • We mark where we will cut.
  • We put the plinth in the gutter of the miter box so that the lower part is pressed against the surface of the device, and the part that will be greased with glue “looks” up.
  • Cut off the area by inserting the saw into one of the 45-degree holes.
  • We correct the cuts with a knife or the same saw (remove irregularities).

Cutting the board at home

You can cut a board at home with tools and equipment such as:

  • a circular saw;
  • hand saw;
  • angle grinder (“angle grinder”).

Each of these options has its own specifics, which is important to consider before starting work, that is, you need to know how to cut a bar or board with this or that tool so that the cut quality is acceptable.

Circular saw – high productivity and ease of use

The circular saw is the best option for the job. It has excellent performance and allows you to cut a considerable number of blanks in a relatively short time, and with high quality. In addition, such a saw allows you to make a longitudinal cut of the material, but you need to know how to cut the board along exactly.

One of the most important criteria when choosing a circular saw is the maximum cutting depth. There are devices on the market that cut materials with a thickness of 30 to 130 mm. That is, you can pick up a machine both for cutting only thin boards, and for sawing bars.

It is also worth paying attention to the cutting tool itself. Discs with a large number of teeth will provide a neat, high-quality cut, while the cutting speed will be low. But discs with a small number of teeth will provide high productivity, but the cut quality will also be worse..

Now about how to cut straight with a circular saw. One of the conditions for high-quality performance of work is reliable fixation of the workpiece. If the material is weakly fixed, then when cutting the board may “go”, and the cut will be uneven.

If the circular saw is hand-held, then all work should be performed on a workbench equipped with stops and guides for the workpieces. Such a device can be made independently, taking any table as a basis..

It is important to set the cutting depth correctly before starting to cut. Some hand saws have an adjustable side guide that can be used to rip through the material. If there is no such device, then use the same workbench..

More convenient in terms of work is the table circular, which is already equipped with everything you need – guides, clamps. Often, such equipment allows you to make and cut workpieces at an angle..

During the sawing process, it is important not to exceed the force on the tool, otherwise the cut quality will be low, the increased load on the saw will lead to a rapid dullness of the cutting blade.

Do not forget about safety precautions when using such equipment. Work should be carried out only after checking the serviceability of the saw and the correct fastening of the workpiece. Also, do not neglect protective equipment – masks, glasses.

A slight inaccuracy and everything will have to be redone. It will help you solve this problem and at the same time fill your hand with a little life hack. It will be the second board, which will remain intact after work. How to do this, read in detail and see the provided step-by-step instructions.

Before cutting the board at an angle with a circular saw, prepare:

Step 1: Using a ruler and pencil, mark the cutting line on the piece of board or plywood you want..

Step 2. Lay the second piece of the board on top of the first, repeating the line with its edge. Beforehand, you can stick small pieces of double tape on the contacting surfaces. They will help to fix the structure so that the boards do not slide out during operation..

Step 3. Turn the boards over so that the worker is on top. Slide the bottom board close to the circular saw blade.

Step 4. Make the desired slant cut by simply guiding the lower board forward in a straight line with the mowing line..

Thus, you can process a board of any length, the cut itself will remain even, and you will spend very little time processing sawn timber..

For carpenters, boards and beams are the most common blanks, of which the production of crafts and wood products is carried out in the future. And the first thing that the material undergoes is sawing into pieces of the required length. At the same time, you should know how to cut the board evenly, because the incorrect execution of this operation can ruin the workpiece or significantly affect the appearance, and not for the better..

At the same time, you should know how to cut the board evenly, because the incorrect execution of this operation can ruin the workpiece or significantly affect the appearance, and not for the better..

At large enterprises, the problem of how to exactly cut a bar or board does not arise. Any serious production has high-precision equipment that performs this type of work. At home, you have to make do with what is at hand. At the same time, you still need to be able to use the tool or equipment correctly in order to saw off the board correctly, and the cut turned out to be flawless.

Note that many companies that sell boards and beams provide cutting services. And for this they use all the same specialized equipment, so the purchased material will be cut efficiently. But it is not always possible to use such a service, and it often happens that you only need to cut one workpiece..

Hacksaw – simplicity and safety

A hacksaw is a simple tool that is quite suitable for work. And although the cutting speed is low, and considerable physical effort is required, but for home conditions such a saw is the most acceptable option..

It is not difficult to cut correctly with a hacksaw on wood. The main condition for a high-quality cut of the material is to make the correct cut. To simplify the task, you can use a regular flat bar, which is used as a guide.

Often the question arises of how to smoothly saw off a board with a hacksaw at an angle. For this, a special carpentry device is used – a miter box. Moreover, it will help not only to make a cut at the desired angle, but also allow any beginner to cut the board exactly..

You can also cut off a bar with a hacksaw. The only problem when working with such a workpiece is that you have to make a lot of effort..

The last option is to use an angle grinder with an installed wheel with teeth for work. But since the “angle grinder” is not intended for cutting wood, this method can only be used as a last resort: attempts to cut the board can result in serious consequences. It’s better to use a hacksaw – it’s time consuming, but safe.
