Sabre saw blade for Siporex 240mm – Professional blade for fast cutting of aerated concrete and brick
Looking for an efficient, fast and durable solution for cutting construction materials such as concrete and hollow brick? The 240mm Concrete Reciprocating Saw Blade (SKU: 10796 or K00083) is a premium tool designed for professional builders and demanding DIYers. This high-quality saw blade delivers exceptional cutting speed, precision and long life, no matter how demanding your project.
Thanks to the advanced tungsten carbide tooth technology and the optimal length of 240 mm, your work on the construction site will be done significantly faster, with less effort and with minimal dust. Forget about useless, dull blades that wear out quickly - invest in a tool that can handle the toughest construction challenges.

Key product benefits and features
This reciprocating saw blade has been developed with maximum productivity and durability in mind when working with abrasive construction materials. Below are the main technical features and benefits it brings to your workshop:

Exceptional durability (Tungsten Carbide): The saw blade teeth are made of high-quality tungsten carbide (TCT). This material is known for its exceptional hardness and wear resistance, allowing for long-term use even when cutting highly abrasive materials such as aerated concrete and brick.
Fast and efficient cutting (2 TPI): With a tooth density of 2 TPI (teeth per inch), this blade provides extremely fast material removal. The coarse teeth ensure that sawdust is quickly removed from the cut, preventing the blade from clogging and overheating.
Durable steel body: The basic body of the blade is made of robust steel, providing the necessary stability, flexibility and resistance to bending or breaking during demanding work.
Optimal length 240 mm: The overall length of 240 mm is ideal for cutting standard cinder blocks and bricks. It allows for deep cuts and easy maneuvering even in tight spaces.
Universal Compatibility: The saw blade is designed with a universal mount, meaning it is compatible with most standard saber saws (foxtail saws) on the market.


Why choose a 240mm saw blade for Siporex?
Cutting construction materials such as aerated concrete (siporex) and honeycomb brick can quickly destroy conventional saw blades. Standard blades made of bimetal or HCS steel dull almost instantly when in contact with abrasive concrete. Our carbide-tipped saw blade is designed to overcome these obstacles.
1. Saving time on the construction site
Thanks to the aggressive tooth geometry (2 TPI) and the power of tungsten carbide, you will cut through Siporex blocks like butter. Faster cuts mean shorter work times and greater efficiency when laying walls, renovating or installing.
2. Less effort and more precision
The stable steel housing prevents the blade from twisting during cutting. This allows you to make perfectly straight and precise cuts, which is crucial for tight joints between building blocks and minimal glue or mortar consumption.
3. Long-term cost-effectiveness
Although carbide blades may seem more expensive than conventional blades, their investment quickly pays for itself. Due to the exceptional lifespan of tungsten carbide, this blade will last significantly longer than dozens of conventional blades combined, saving you money and time in the long run on constant tool changes.

Frequently Asked Questions (FAQ)
Does this saw blade fit my reciprocating saw?
Yes, the saw blade has a standard universal mount that is compatible with most established brands of reciprocating saws on the market (such as Makita, Bosch, DeWalt, Milwaukee, Einhell, Parkside and others).
Can I also cut classic concrete or reinforced concrete with this blade?
No, this blade is intended exclusively for aerated concrete (siporex) and honeycomb (hollow) brick. Cutting classic concrete, stone or reinforced concrete (with iron reinforcement) can damage the carbide teeth and destroy the blade.
How can I extend the life of my saw blade when cutting Siporex?
For maximum life, we recommend that you do not apply too much pressure to the saw while cutting. Let the weight of the machine and the aggressive tungsten carbide teeth do their work. Also, avoid cutting at too high a speed, as excessive heat can affect the bonding of the carbide tips.

Instructions for using the product:
• Before use, check the saw blade, teeth and attachment for cracks, bends or other damage.
• Check that the 240 mm blade is compatible with your reciprocating saw.
• Always unplug the reciprocating saw or remove the battery before changing the blade.
• Insert the sheet correctly into the clamping mechanism and check that it is securely fastened.
• Properly support and secure the workpiece or block of Siporex.
• Only start the saw when the blade is free and not touching unwanted objects.
• Guide the sheet through the cementitious mortar with even pressure and without excessive force.
• After completing the cut, turn off the saw and wait for the blade to come to a complete stop before removing or putting it away.

Useful tips for work:
• Use the sheet primarily for aerated concrete and materials for which it is specifically suitable.
• Before cutting, mark the cutting line to ensure the cut is as accurate as possible.
• For longer cuts, guide the saw evenly and let the teeth do the cutting.
• Do not apply too much pressure as this may reduce cutting efficiency or damage the blade.
• A considerable amount of mineral dust is generated during cutting, so it is recommended to use extraction when compatible with the tool.
• After use, remove the dust from the blade and store it in a way that does not damage the teeth.
• If you notice reduced cutting efficiency, damaged teeth or deformation of the blade, replace it.

Warnings:
⚠️ Always unplug the reciprocating saw from the power supply or remove the battery before changing the saw blade.⚠️ The saw blade is sharp - wear protective gloves when handling and be careful of the teeth.⚠️ Do not use a bent, cracked or otherwise damaged saw blade.⚠️ Before use, check that the blade is correctly and securely installed in the clamping mechanism.⚠️ Keep hands and fingers away from the cutting path and the moving saw blade.⚠️ Cutting Siporex generates mineral dust - ensure good ventilation, use extraction and appropriate respiratory protection.⚠️ Wear safety glasses and hearing protection when working.⚠️ Before cutting, check that there are no electrical cables, pipes or other hidden objects in the material.⚠️ Do not lift or put down the saw until the saw blade has come to a complete stop.⚠️ Only use the saw blade in a compatible reciprocating saw and for the intended material.

Same summary

The 240mm reciprocating saw blade for concrete is designed specifically for users who perform construction or demolition work where greater reach and robustness are required. Its length and material selection allow for efficient cutting of lightweight construction materials such as concrete, making it suitable for home renovation or professional construction jobs. It is recommended to check before use that the blade attachment is compatible with your saw and to note that this model is less suitable for precise cuts in hard materials or metal. The special feature of this blade is the balance between length and strength, which makes it particularly suitable for working with larger pieces of concrete, where cutting speed is a priority over extreme precision.

Answers to frequently asked questions

Which materials is the saw blade best suited for?

This saw blade is particularly suitable for cutting chipboard and similar lightweight building materials, but is not suitable for metal or extremely hard wood.

Is the saw blade compatible with all reciprocating saws?

Before purchasing, check that the saw blade attachment is compatible with your reciprocating saw; most standard saws are compatible, but we recommend checking for trouble-free use.

How long should a saw blade last under normal use?

With normal use when cutting Siporex, the saw blade maintains its effectiveness for several projects, but the lifespan is affected by the frequency of use and the correct choice of blade material.

Is this saw blade also suitable for precision cutting?

This model is more suitable for fast and rough cuts of larger pieces of chipboard, where accuracy is not the main advantage; for finer cuts, we recommend using a blade with a higher TPI.

What to do if the saw blade becomes dull or worn?

When the effectiveness of the saw blade decreases, replace it with a new one, as using a dull blade negatively affects the quality and speed of cutting and can put strain on your saw.
