When we talked about the properties, advantages and disadvantages of aerated concrete, we mentioned among the advantages that it is easy to cut and drill. According to experts, in terms of sawing, aerated concrete blocks are noticeably easier than brick. However, so that there are no cracks in the wall, the masonry went as smoothly as possible, everything was correct, we will consider all the suitable tools and features of their use.

Hacksaw

If you have to build a relatively small private house of a simple shape from aerated concrete blocks, without arches and columns, then you can use an ordinary hacksaw for cutting as the most affordable and inexpensive tool.

Experts advise choosing a thick metal hacksaw for cutting aerated concrete, on the teeth of which there are victorious solders. This will have a positive effect on the accuracy of the cut and the safety of the tool..

However, according to user reviews, it is quite possible to use a hacksaw with a large hardened tooth, thick enough so that it does not go to the side when cutting. It will, of course, become dull after working with several aerated concrete blocks, but it is easier to sharpen it or buy a second one than to spend money on a hacksaw with soldered teeth.

The technique of cutting aerated concrete with a hacksaw requires marking with a regular pencil and a metal triangle.

Important! The easiest way is to cut aerated concrete while it is dry, during the warm season. Wet material will resist cutting much more, the hacksaw will knit.

The saw blade should be long enough, it is better to cut at an angle of 45 degrees, making cuts along different edges and taking care that the cut piece of the block does not fall or break. The main thing is that the saw does not go away from the marking, otherwise the cut will turn out to be beveled, there will be no even masonry!

There is a special hacksaw for aerated concrete of about 650-800 rubles.

Reciprocating saw

If you have a large amount of work with aerated concrete, instead of a hacksaw, it is better to choose a reciprocating saw, the choice of which we wrote in detail about. Of course, saber saws are more expensive than hacksaws – from 5 to 20 thousand rubles. But this is an electric tool, which is faster and easier to use than a hacksaw..

For a reciprocating saw, it is important to choose a special blade for aerated concrete. Users are advised to make pendulum movements with the reciprocating saw, as if you are using a hand hacksaw, so that the blade does not get stuck in the material.

Electric circular saw

This tool copes with aerated concrete blocks quickly, but a lot of dust is generated during the sawing process, eye protection is necessary. At the same time, this tool costs less than a reciprocating saw – from 2.5 thousand rubles.

Chain saw

There are advantages to using a chain saw for cutting aerated concrete, but there are more disadvantages. Yes, it cuts fast, it helps to cut U-shapes, it is convenient for cutting at an angle. But in the process of cutting, the electric chain saw quickly becomes blunt, you need a chain with victorious solders, which is much more expensive than usual. In addition, the chain heats up in the process, the tool needs a break..

It turns out that the use of an electric chain saw is more convenient than a saber saw, but it becomes unusable faster, replacing the chain will lead to additional costs.

Saw “Alligator”

The most powerful, but at the same time expensive option for cutting aerated concrete blocks. In general, the principle of operation of the “Alligator” is similar to a reciprocating saw, but the device is more convenient and more powerful, therefore it acts faster. In addition, such a tool has a knife brake and a switch lock, an aluminum case for protection against dust, components are easy to replace, and the blades move towards each other, which ensures the stability of aerated concrete.

The downside of the Alligator is the price. It starts from 40 thousand rubles and can exceed 60 thousand rubles. Typically, such saws for cutting aerated concrete blocks are used by professionals involved in the construction of houses from this material..

Choose the right tool for cutting aerated concrete, depending on your needs and skills. Often, a special hacksaw is enough to do everything quickly and competently. Aerated concrete cutting machines are usually used only by professionals, although there are homemade options created by craftsmen.
