Cutting disc KWB 721140

The KWB 721140 cutting disc is a thin DIAMANT turbo blade with a 1.0 mm cutting edge designed for high cutting performance and extended professional use on stone materials. It fits common angle grinders, including cordless models, and is suitable for cutting granite, marble, concrete, ceramics, tiles, stoneware, and natural or artificial stone at a circumferential speed of 80 m/s.

Advantages

The extra-thin 1.0 mm cutting edge and turbo segment shape provide fast cutting with reduced material removal and less chipping on brittle stone and ceramic surfaces. The blade is balanced for use in standard angle grinders and cordless angle grinders, offering long-term durability under professional workloads. Compatibility with a wide range of brands and a lightweight design (approx. 80 g) make handling easier during precision tasks.

How to use

Mount the disc on a compatible angle grinder according to the grinder manufacturer's instructions, ensuring the rated circumferential speed does not exceed 80 m/s. Secure the disc with the correct flange and tighten to the recommended torque. When cutting, use steady feed pressure, keep the workpiece supported, and allow the blade to do the cutting without forcing. For best results on tiles and ceramics, score first if necessary and cut at a moderate speed to minimise chipping.

Usage recommendations

Wear appropriate personal protective equipment—eye protection, gloves, hearing protection and a dust mask—when cutting stone and ceramic materials. Inspect the disc before use for cracks or damage and replace if any defects are found. Use water cooling only if the disc and grinder are rated for wet cutting; otherwise operate dry and avoid overheating by taking breaks during extended cuts.
