When is it necessary to cut an expanded clay product??
Cutting and sawing expanded clay concrete blocks is a necessary step in the construction process. These situations may necessitate this procedure:
- Wiring, installation of sockets and switches.
- Laying communications.
- Forming arches and corners when making window and door openings.
- Space redevelopment.
- Changing the block size.
- Finishing corners.
What tools can you use to cut??
Expanded clay concrete blocks are cut using hand and power tools. A hacksaw, reciprocating saw, Alligator saw, or grinder can be used to symbolize it. You should research the tool’s capabilities, benefits, and drawbacks before making a decision.
Hand saw
A power source is not necessary for using a manual hacksaw to cut expanded clay concrete blocks; it is a universal tool. It is symbolized by a metal blade with teeth and a grip handle.

Benefits of it:
- Ease of use.
- Affordable price.
- Light weight.
- Wear resistance of the fabric.
- High cut quality, no need for reprocessing.
- Low noise level during work.
- Convenient placement of the tool handle.
Disadvantages of a hand saw
- The need for physical force.
- Difficulty in controlling cutting accuracy.
- Time costs.
You must select a hacksaw with a thick blade and hard soldered teeth if you plan to work with blocks. The instrument is appropriate for cutting a limited quantity of blocks. It is preferable to use a power tool if extensive work is ahead.
Counseling! Selecting a hacksaw with an HM or CT marking is preferable when cutting expanded clay concrete. Because they are composed of high-strength steel, their blades do not shatter when they come into contact with hard surfaces.
Saws
You can use an Alligator saw or a reciprocating saw for work. Every one of them has unique qualities, benefits, and drawbacks.
Saber
This power tool has excellent performance. The fundamental working principle of it is essentially the same as that of a hand hacksaw. The sole distinction is that the instrument is powered by an electric drive and operates through its own reciprocating movements.

Advantages of a saw that reciprocates:
- High power.
- Possibility of up to 3000 rpm (exact values depend on the selected model).
- Ability to change the speed of the tool.
- High cutting speed.
- Tool maneuverability and low weight. Even a woman can easily hold it in her hands.
- Safety of use, presence of a locking button.
- Affordable price.
Cutting expanded clay concrete is just one application for a reciprocating saw; it can also be used for other materials.
Drawbacks of the instrument:
- Low cutting accuracy.
- Weak performance (subject to comparison with an angle grinder).
- Vibration of the saw during operation. To eliminate this drawback, you need to choose a device with an anti-vibration system.
Alligator
This is an electrically powered professional tool. It features two canvases that move in reciprocal relation to one another. The reason the saw acquired such an odd moniker is that, in the switchboy, it moves similarly to the crocodile’s jaw.

The following are some benefits of cutting expanded clay concrete blocks with an alligator saw:
- Smooth cut.
- No vibration.
- Ability to work with blocks of different thicknesses.
- Ease of use.
- No reactive recoil when jammed.
The tool’s drawbacks consist of:
- High price.
- Possibility of cutting into the surface only from the edge.
There are no limitations when using expanded clay concrete blocks with the Alligator saw. Professional builders therefore always carry one of these tools in their toolbox.
Bulgarian
One of the varieties of circular saws is the grinder. It is the best tool, according to builders, for cutting expanded clay concrete blocks.

Benefits
- High cutting precision.
- No need for significant physical force.
- High speed of work.
Drawbacks:
- High price.
- Excessive dust formation.
- The restriction of the cut with a radius of the disk, so it is performed to the maximum depth, after which the block is split. To do this, insert an axe into the cut and hit it with a hammer.
Counseling! You should use a segmented diamond disc with a 230 mm radius to cut expanded clay concrete. Utilizing an alternative working element will cause the blocks to overheat and explode. This may result in harm.
The following features should be present in the tool used to cut expanded clay concrete blocks:
- The presence of a speed control function.
- The presence of a dust collection casing.
- A comfortable handle for gripping the tool.
- Small weight of the product, which should not exceed 5 kg.
Although Chinese models are less expensive than equipment made by European manufacturers, their continuous operation is not guaranteed.
What else might be needed for work?
In order to cut a block, you must ensure that additional tools are available.
- A stand on which the building material will be sawed.
- Pencil for a flat line.
- Construction square.
- Ax or wooden block. They will be needed if the work is done using an angle grinder.
- Support shoe. It will allow you to securely press the saw to the block, perform the job faster and more accurately, and improve the quality of the cut. The shoe can be moved along the canvas and rotated at the desired angle. Most often this device is used when working with a reciprocating saw.
- Personal protective equipment: construction glasses, respirator, gloves.
If work is being done in a room with furniture, the furniture needs to be covered with plastic wrap to keep out dust.
Occasionally, the block just needs to have a hole drilled for a dowel or anchor bolt; it doesn’t need to be entirely cut. The work needs to be done carefully with a hammer drill or a drill with a carbide tip because the material is delicate. Use an impact drill to create a through hole if necessary.
Step-by-step instruction
Following these guidelines will help you cut the expanded clay concrete block:

- To make a flat line, it must be drawn in advance. To do this, use a pencil and a square. With their help, marking four faces are applied.
- First, cuts are performed, which are made to a depth of up to 3 cm.
- Using the selected tool, perform a full cut of the unit.
- You need to act carefully, excluding gross power. This will allow you to keep the tool evenly, not to take it to the side.
- You need to cut the block on the stand to avoid falling a cut piece and damage to the flooring.
- If the work is performed by a grinder, then the drink is done to the maximum possible depth, after which they have a part of the block with an ax, gently hit the hammer on it.
Difficulties and errors
Selecting a hacksaw with a small number of teeth may cause problems with the block cut. The more and better the slice, the more of them there are and the closer they are to one another.
When working with a power tool, a large amount of dust is produced. As a result, you must consider respiratory protection beforehand. It’s essential to take breaks from work when using an electric saw or grinder to cut blocks. This will enable the tool to cool down and allow the dust to settle a little.
No, a chainsaw is not suitable for cutting blocks. Such a load is too much for her chain to bear. Work-related dust accumulation will cause the tool’s components to become clogged and eventually break.
| Method | Advice |
| Hand Saw | Use a hand saw with carbide-tipped teeth for straight cuts. Go slow and steady. |
| Power Saw | A circular saw with a diamond blade makes quick, precise cuts. Wear safety gear to protect from dust. |
| Masonry Chisel and Hammer | Great for small adjustments. Mark your line, score it with the chisel, then tap along the score to split. |
| Angle Grinder | Good for detailed work. Use a diamond blade and make sure to cut in a well-ventilated area to avoid dust buildup. |
| Reciprocating Saw | Perfect for awkward cuts. Use a blade designed for masonry and let the saw do the work without forcing it. |
Cutting concrete blocks made of expanded clay doesn’t have to be a difficult undertaking. You can accomplish precise and clean cuts with the appropriate equipment and techniques, which will streamline and increase the effectiveness of your construction project.
Masonry saws and chisels are excellent hand tools for smaller tasks or situations requiring accuracy. They are adaptable to a variety of circumstances because they are simple to operate and don’t require electricity. Power tools with diamond blades, such as circular saws or angle grinders, can save you time and effort on larger projects. These tools are fast and powerful enough to quickly cut through expanded clay concrete blocks, but because of their speed and power, additional safety precautions are needed.
Always remember to protect yourself from dust and debris by donning the appropriate safety gear, such as goggles, gloves, and a dust mask. Taking your time and making sure your tools are in good working order will also assist you in getting the greatest outcomes. Furthermore, costly errors can be avoided by following a clear plan and taking precise measurements before making any cuts.
