KWB 491912 Sanding Disc Set 5 Pieces

Sanding disc set KWB 491912 contains five 125 mm abrasive discs designed as replacement accessories for compatible random orbit sanders. The discs use aluminium oxide abrasive bonded with phenolic resin on a strong backing and feature a hook-and-loop fabric attachment and punched holes for dust extraction. They are intended for sanding wood, metal, paint, varnish and filler depending on the chosen grit.

Advantages

The discs combine aluminium oxide abrasive with a phenolic resin bond for balanced wear resistance and cutting performance. A reinforced backing provides stability during use, while the hook-and-loop fabric backing allows quick attachment and convenient disc changes. Punched holes improve dust extraction when used with a compatible sander and dust collection system.

Key specifications

How to use

Select the appropriate grit disc for the task and attach it to a compatible 125 mm random orbit sander using the hook-and-loop backing. Ensure the disc’s punched holes align with the sander’s dust extraction ports if available. Operate the sander at the recommended speed for the material, applying even pressure and moving the tool smoothly across the surface to avoid grooves or burns. Replace discs when abrasive performance decreases.

Recommendations

For best results, choose grit according to the work: coarser grits for material removal and paint stripping, medium grits for smoothing, and finer grits for final finishing. Use appropriate personal protective equipment (dust mask, eye protection, hearing protection) and connect a dust extraction system where possible. Store discs flat and dry to maintain shape and performance.
