Keltin masonry saw blade 305 mm 20T for aerated concrete

Keltin masonry saw blade 305 mm 20T for aerated concrete is a circular cutting blade designed specifically for straight, accurate cuts in aerated (cellular) concrete blocks and panels. With a 305 mm diameter and 20 teeth, the blade mounts on standard circular saws and is intended for use in construction and renovation tasks where efficient removal of material and clean edge quality are required. The design balances cutting speed and surface finish to meet common on-site needs.

Advantages

The blade's tooth count and geometry are optimised for cutting lightweight masonry, reducing block dust and chipping while maintaining a steady feed rate. Its construction provides stability during operation, which helps achieve uniform cut depth and alignment. Compatibility with standard circular saws makes the blade a convenient option for tradespeople and DIY users working with aerated concrete. The 305 mm diameter offers a practical cutting depth for most masonry panels and blocks used in modern building projects.

Suitable for

• Cutting aerated (cellular) concrete blocks and panels
• Straight cuts for load-bearing and non-load-bearing masonry elements
• On-site renovation and installation tasks requiring quick, repeatable cuts
• Carpentry workshops and construction crews using standard circular saws

Key specifications

• Blade diameter: 305 mm
• Number of teeth: 20
• Material application: aerated (cellular) concrete and lightweight masonry
• Mounting: compatible with standard circular saw arbors matching the diameter
• Cut type: straight cutting for panels and blocks

How to use

Install the blade onto a compatible circular saw following the saw manufacturer's instructions and ensure the blade is secured and properly aligned. Verify that the saw's speed and power rating match the blade's recommended operating conditions. Mark the cutting line on the aerated concrete, support the workpiece to prevent movement, and make steady, controlled passes to achieve an even cut. Use appropriate cutting speed to avoid excessive dust and minimize chipping at the edge of the material.

Usage recommendations

Use appropriate personal protective equipment — eye protection, dust mask or respirator, hearing protection, and gloves. Employ dust extraction or wet cutting methods where possible to reduce airborne particles. Allow the blade to cool between long cutting runs and inspect it regularly for wear or damage; replace the blade when cutting performance or edge quality declines.
