Sanding Disc for Concrete and Stone Bosch 180 mm Round K40, Pack of 5

Bosch 180 mm round sanding discs, grit K40, are abrasive discs designed for use on concrete and natural or artificial stone. Supplied as a pack of five, these 180 mm round discs are intended for aggressive material removal, surface leveling and rough shaping in construction, renovation and masonry tasks. The discs fit angle grinders and surface grinders that accept 180 mm round sanding pads and are engineered to withstand heavy-duty grinding on mineral substrates.

Advantages

These Bosch sanding discs provide fast stock removal on concrete and stone due to their coarse K40 abrasive grain, ensuring efficient progression on rough surfaces. The 180 mm round shape ensures consistent contact with flat and slightly contoured areas, improving work speed and uniformity. Supplied in a five-piece pack, they offer immediate replacement availability for continuous work. Manufactured to Bosch quality standards, the discs combine aggressive cutting performance with durability for construction site use.

How to use

Attach the 180 mm sanding disc securely to an angle grinder or surface grinder that accepts round 180 mm abrasive discs, following the machine manufacturer’s instructions. Start grinding at low speed to position the disc, then apply steady, even pressure while moving across the work surface to avoid gouging. Use coarse K40 for aggressive removal; finish operations with finer abrasives if a smoother surface is required. Observe recommended rotational speeds for the disc and allow the tool to cool periodically during heavy use.

Usage recommendations

Wear appropriate personal protective equipment including safety glasses, dust mask or respirator, hearing protection and gloves. Use dust extraction when possible to reduce airborne particles. Do not exceed the grinder’s recommended speed for 180 mm discs and avoid side-loading the disc beyond the intended contact to prevent premature wear or damage.
