Therefore, first we cut all the upper waves on one side, and then we turn the sheet over and combine the cut lines from the back.

The main problem is dust in order to bring it down; during operation, the disc and sheet are constantly watered with water.

Step-by-step scheme for cutting straight sheets with an angle grinder.

An angle grinder is the most common, but not the only power tool with which to cut asbestos-cement sheets. The second in the ranking is a miter circular saw.

True, for such purposes, only its manual modification is more suitable, and it is also better to take a diamond blade, models designed for cutting wood quickly sit down.

Cutting slate with a circular saw is also convenient, as well as an angle grinder.

Another representative of the disk community of power tools suitable for cutting asbestos cement slabs and specifically slate is a cutting machine. Over, this tool was specially developed for such purposes. In fact, it is one of the modifications of an angle grinder adapted to cut slate.

It is easiest to cut a slate with a cutting machine, since it is for this purpose intended.

Method number 2: cutter

At a time when grinders and other similar power tools did not yet have experienced craftsmen, they used steel cutters to cut sheets. The main requirement for such cutters is as strong steel as possible.

  • A metal ruler is pressed along the cut line;
  • Further, relying on this line and with great pressure, several dozen cuts are performed. The number of cuts depends on the strength level of the sheet and the quality of the cutter;
  • When the furrow from the cutter reaches half the thickness of the material, the sheet is placed on the edge of the table and breaks off with a light pressure.

The technique of working with a steel cutter is extremely simple.

The problem is that flat sheets can be cut with a cutter anywhere, and a wavy slate according to this pattern is cut only along the wave.

There is a professional tool with which you can perform such work, but it is often taken only by people engaged in such work, in everyday life it can be used little.

There is a professional tool for working with slate and slate.

According to the technology described above, the slate can be cut with a sharp boot knife made of high-strength steel, but only the blade quickly “sits down” with such cutting and few agree to spoil a good knife.

Our wise people have adapted to make such cutters from a broken hacksaw blade for cutting metal. A groove is made on the reverse side of the web, resulting in a kind of tooth that cuts sheet materials perfectly.

And to hold it was more convenient, the handle is wrapped with electrical tape. The tool, of course, is far from ideal, but its indisputable advantage here is its cheapness. After all, you would have thrown away the broken canvas anyway, and so it will go into action.

A hacksaw blade cutter is an inexpensive and fairly effective tool.

By the way, such a folk cutter made from a hacksaw blade can cut not only asbestos-cement sheets, but also textolite, gitinaks, as well as any kind of plastic.

Method number 3: punch

The above methods work, of course, well, but what if the tool at hand is just a hammer and slate nails? It turns out that there is also a way out of this situation:

  • You simply lay the sheet on the ground and mark the cut line on it;
  • Then take a nail and punch a series of holes along the line. You only need to beat at the bottom of the wave, the one that rests on the ground;
  • Now turn the sheet over on the other side and hit the row of holes in the line, again at the bottom of the wave;
  • As a result, along the cut line, you have an even row of holes with a step of the order of 5. 7 mm. You only need to lean the sheet against some even edge and break it off along the cut line.

It is impossible to achieve a flat edge with a punch.

What is a flat slate?

First, answer the following question: how much slate do you need to cut? The fact is that some tools are easiest to use for a small amount of work, and completely different are needed with a different approach.

Secondly, flat slate today is produced in very different widths, composition and even the percentage of asbestos content. All this in turn depends on how long the fibers are, what is their diameter and how evenly they are arranged. All this in production is controlled by GOST18124-95.

How to Cut Textolite 10 mm

The difference between wavy and flat slate is that the latter is much thicker. Have you ever wondered why metal tiles, profiles and other similar roofing materials look exactly like that? Is it really all about decor? In fact, the profiled shape gives the material additional bending stiffness as well as durability. Why the thickness of the sheets themselves can already be made thinner. But the flat slate is already more dense and more fragile.

In general, you can deal with two types of slate:

  • Pressed, which is distinguished by its strength and durability.
  • Unpressed, which is made from economical raw materials and usually serves for purposes such as temporary roofing or foundation formwork.

Typically, the thickness of a flat slate is in the range of 4-5 mm, but one whose parameters are from 8 to 10 mm is considered durable. Flat slate with a thickness of 10 mm is often used in the roof of small outbuildings. It is weatherproof and most affordable.

How to cut slate without any dust

If the wave slate is quite difficult to cut because of its shape, then the flat slate is so simple that it is easier to break. Why so? The fact is that when cutting slate a lot of dust is released, which is harmful not only to the tool, as we just said, but also to your health. Therefore, those who protect both the one and the other find many ways how to do without cutting at all. Over, because of the large amount of dust, it is not recommended to cut the slate indoors. It remains only to break it.

Slate really breaks easily. All thanks to its fibrous structure. It is only important to do it smoothly without damaging the corners. And for this there are as many as three ways:

Method number 1. Breaking thin slate

So, the easiest way is to outline the desired cut line, draw it with something sharp, place a bar and gently break the slate:

  1. Mark with a pencil the place of the future fracture.
  2. Lay the rail on the cut line.
  3. Put the slate on the table and press evenly on the area to be broken off.

Or they just cut a 1 mm hole. A flat slate will easily break in this place.

Method number 2. We break the slate with a nail

  1. Mark the cut with a simple pencil.
  2. Mark this line with a sharp nail.
  3. Hammer this nail into the line every 2 cm. The more holes you make, the easier it will be for you to break the sheet.
  4. Having pressed on a slate fragment, easily break it along the punctured line.

Method number 3. We saw tight slate

  1. Lay the slate on a flat table so that most of the material is on the countertop. Let the assistant hold the hanging part of the slate.
  2. Take a saw and start sawing a sheet just like a thin wooden board or plywood.

The hacksaw is also suitable for cutting slate on foam concrete.

Method number 4. Cut the slate with a cutter

If you have to cut a flat slate directly in the room. Forget about power tools, too much dust and noise. Take a good steel cutter and follow these instructions:

  • Step 1. Lay the slate sheet in a flat place.
  • Step 2. Attach a ruler and draw a line under it with a cutter.
  • Step 3. Remove the ruler, and begin to press harder on the cutter, deepening and expanding the fishing line.
  • Step 4. Now place a rail or pipe under the sheet parallel to the cut line, press. And it’s not necessary to press hard, otherwise the slate will simply crack.
  • Step 5. If any piece does not come off, tap the cut line with the side of the hammer.

If there is no other equipment at hand, most often flat slate is sawed with a fine-tooth hacksaw. True, from time to time it will have to be sharpened.

How to cut slate with special tools

So, how to cut a flat slate, if you still have to cut it?

We cut the angle grinder: we select a disk

So, to cut a large amount of flat slate, take an angle grinder with a diamond blade. Cutting the slate will be quick, accurate, even and safe. The only negative when working with this tool is a lot of dust. But the relatively cheap angle grinder can easily cope with this task.

When working with an angle grinder, grab it by one handle and drag it towards you. Under the own weight of the tool, everything will cut well:

How to Cut Textolite 10 mm

The diamond wheel cuts flat slate easily and quickly. As for the disk revolutions, 2000-3000 allow you to work easily and the tool does not heat up. By the way, with the help of an angle grinder and a diamond disk, you can immediately grind the edges of the slate. Tip: when working with an angle grinder, also put on protective headphones. The sound will not be pleasant.

One of the most affordable and practical options is a stone cutting wheel that can be inserted into the cheapest simple angle grinder.

Another good way that is often practiced today is to make only an incision on a slate using an angle grinder, and then break the sheet.

We cut with a saw: we select a coating and teeth

Perfectly cuts a slate saw with a special Teflon coating, which on the one hand protects the saw blade, and on the other, significantly reduces friction with the material. And less friction. Less dust and easier work. Such a saw is not much more expensive than usual.

Secondly, you should pay attention to the teeth of the saw: the larger they are, the faster the slate will be sawed. And it’s definitely faster than a simple hacksaw.

We cut with an electric saw and a chisel

This slate is traditionally cut with a chisel and circular electric saw:

  1. We take a ruler, a sharp chisel and make notches on both sides of the future section.
  2. We place the slate on a flat base with a sharp bar or face so that the lines coincide.
  3. Carefully break the slate.
  4. If the slate could not break, we cut it with a circular electric saw, cooling it with water from time to time.

Stroborez cut

Another suitable tool is a chipper. He has a built-in diamond blade, which is able to achieve high speed revolutions. But, because This “toy” is expensive (because it’s professional), but because home craftsmen do something like it themselves: they connect a parquet and a fine-toothed circle on a tree. Cutting slate with this tool is quite convenient.

Cutting with a jigsaw

But the worst is that an ordinary cheap jigsaw can do this. It wears out too quickly. Most suitable for such work is a jigsaw with a HCS saw made of high carbon steel, which is designed to work with soft materials.

It also copes with cutting a flat slate with a jigsaw with a file, on each tooth of which a victory tip is soldered. Such a tool is convenient not only to cut sheets according to certain parameters, but also to make curves and arcs.

Another good option, especially if you have to work with slate often and professionally, is a jigsaw with a BIM saw. When cutting sheets, such a tool will never break even thin corners of a flat slate.

We cut on a home circular

Cutting a flat slate is also not difficult on a regular circular, 2 kW. Put a circle with carbide taps on the tree so that there are more teeth. It turns out everything quickly and without any problems. Wear safety glasses, wide-sleeved clothing, and durable gloves. It is only important that the sheet itself is fixed.

If you use a manual circular, then set the speed in the range of 3500-4000. So the slate will cut evenly and much cleaner than with a maximum turnover of 5500.

How to minimize the amount of asbestos dust?

Opinions about the dangers of inhaled asbestos fibers today are very different, and even completely opposite. Our compatriots, for example, who worked all their lives in factories with slate without any masks, do not have any health problems regarding the respiratory tract.

But British doctors say that it’s worth only once to inhale asbestos dust in order to detect lung cancer in 20 years. Over, with one breath, up to 700 thousand harmful fibers enter the body at the same time!

Take one thing into account: asbestos dust is really harmful in the course of active operations with slate. And this, first of all, its sawing.

A bit about asbestophobia

So, let’s start from the beginning. The most common slate, which has been roofing houses for several decades, consists of the following components:

In addition, some experts have the opinion that only dust from amphibole asbestos, which is mined in Africa and is not used in domestic flat slate, is carcinogenic (only chrysotype asbestos is used here).

For example, amphibole asbestos was banned several years ago in such large countries as Germany and the United States. Billions were spent looking for artificial substitutes and the struggle for markets for new materials has become particularly fierce.

Chrysotile asbestos is another type of roofing slate. Strong and refractory material is produced and used to this day, with 50% of it being exported to other countries. The price for it is low, and therefore it is difficult to talk about competition. Why are the reports of world media about the unexpected carcinogenicity of all materials containing not only amphibole asbestos, but also chrysotile asbestos, most Russian scientists perceive critically. As a normal competitive attack on the international market. Although it is worth noting that the issue of banning the use of this raw material is now raised quite high.

The whole problem is that asbestos fibers tend to irritate lung tissue. And constantly, because of which the body first produces benign tumors in such places, and these can degenerate over time. On the other hand, glass and cement can cause the same problems. Those. Almost every person can have micro-tumors in the lungs, but they can degenerate into malignant ones only in people predisposed to cancer. Therefore, be that as it may, the airways must be closed to all participants in the process.

Secret number 1. We use construction tape

Secret number 2. Pour water generously

Water will significantly reduce the amount of dust. Soak the slate before cutting. Over, moisture, in turn, will also facilitate the process itself, additionally protecting the instrument used from dullness.

It will be easier for you to do this in stages:

  • Step 1. Drive the disc along the wet cut line, only effortlessly.
  • Step 2. Moisten the risk once again with water.
  • Step 3. Swipe it again with the machine, this time deepening the risk, but again without effort. The weight of the tool is enough.
  • Step 4. Wet the risk again with water.
  • Step 5. Repeat all this three to four times.
  • Step 6. Easily break the slate along the finished line.

Well, if you can take an assistant. You will cut, and he will moisten the place of cut with a stream of water from a bottle or hose. But another option to moisten the place of the cut without direct contact of water with electricity is to moisten the rag and leave it on the next cut for half an hour.

Let’s say this is the most accurate and healthiest way to cut. Wet slate will naturally emit far less asbestos dust than dry. In this case, the dust combines with water and you get such a paste. Believe me, pasta is already better. You can’t inhale it. Be sure to rinse the resulting dirt from water and asbestos dust with water from a hose. Both from tools and from sheets. Otherwise, if it hardens, it will not be washed off.

On the other hand, water can damage the angle grinder itself, and therefore it is not worth literally pouring this particular tool. Naturally, when working with electricity included in the outlet, water for the instrument does not need to be poured. Just add from the spray gun. Just be careful: sheets from moisture become not only more elastic, but also fragile. And keep in mind that water does not cope with asbestos dust by 100%, and therefore you need to work with a quality respirator and glasses.

Secret number 3. Equip a dust collector

An ordinary vacuum cleaner will also help to cope with dust while cutting slate: just ask an assistant to put the pipe near the cut line and move after you.

Secret number 4. We select weather conditions

Another important point: a person with a cutting tool should stand so that the wind lifts dust from him in the opposite direction.

You will be surprised, but it’s easiest to cut flat slate. In winter. The fact is that snow generally likes to attract dust. And now all the harmful particles will remain under the cut, you just need to put slate sheets on it.

As you can see, Russian masters have already adapted to everything!

The use of slate screws. How to drill correctly

Self-tapping screws for mounting slate are highly durable. Therefore, the use of such fasteners is much more preferable than forced drilling of slate. Over, self-tapping screws can be selected in length and color so that they are combined with the shade of the coating and do not stand out. On sale there are also self-tapping screws equipped with a special drill or pen. The clutch makes it very easy to make a hole in the slate, without significant effort. So if you are still in doubt about how to drill a slate sheet, opt for such mounts. For work, you need only a screwdriver, wrench or screwdriver. It is worth noting that self-tapping screws with drills are more expensive than nails, however, they are much more convenient to use.

Before laying the roofing from slate, it is worth checking how well the crate for fixing the material is made, and whether the gutters are installed. It is advisable to build a water drainage system before the start of roofing, since then it will be much more difficult.

Places where the material was cut, and ideally the entire surface of the roof, it is desirable to cover with acrylic paint or a special water-repellent composition. Joints between sheets can be sealed with construction foam. When laying the slate, make sure that each subsequent row is laid on top of the previous one. Then water can freely drain from the roof surface.

Trimming material

When working with slate, it is important to know not only how to make a hole in the slate, but also how to properly trim it.

Experienced builders use several methods:

  1. To work with slate, you can use an angle grinder with a disk for stone. Such work should be performed in pairs. The fact is that as the slate sheet is sawn, small particles of asbestos are released, which quickly rise into the air. Therefore, one person must water the place of cut with water, while the other cuts the material.
  2. To cut the slate, you can use an angle grinder with a diamond wheel. The advantages of this method are that it will make it possible to make a drank of any configuration. In addition, during operation, parallel grinding of the edges of the sheet is possible. In this case, even more asbestos dust is formed, so it is only necessary to work with safety glasses and a respirator. It is advisable to do this outdoors. Before starting work, you need to wet the line of the future cut well and wait a few hours. As a result, sawing slate will be much more convenient and easier. Nevertheless, the work must be done as carefully as possible so that the slate does not crack.
  3. For cutting slate, a cutting machine is used. This uses a disk to work with stone. First of all, the cut contour is watered abundantly with water. Next, make the first cut with a stone along the contour. The resulting recess is again well moistened. Then do re-penetration by the disk. Approximately four approaches will be required to make a notch of sufficient depth. In the end, along this circuit, it will be easy to break off the slate.
  4. To work with flat slate, a cutter is usually used. First, markup is made on the material, along which a cutter is drawn under the ruler. You need to do 3-4 repetitions. After enough deepening is obtained, the pieces of slate break off along the contour. It is noteworthy that with this method of operation of asbestos particles, very little appears. Alternatively, you can use a traditional hacksaw or electric jigsaw running at low speeds. In any case, the cutting of slate should be carried out very carefully so that the material does not break.

We have given only the simplest and most affordable ways of sawing slate. In fact, there are many more. For example, professional builders use much more sophisticated methods and tools. But home masters can use the available devices, based on their own skills and capabilities.

Types of Slate

Among roofers, several types of materials are called slate; their individual technical parameters directly affect the choice of cutting method and tool.
