BOSCH hook-and-loop multi-hole sanding discs are made with high-quality calcium stearate grit for speed and durability in tough environments. The multi-hole design optimizes dust extraction. Open-coat, resin-bonded calcium stearate abrasive provides long life and fast material removal on wood and other surfaces. These discs are engineered to help ensure the disc resists clogging for performance and stability. They provide cabinet makers, refinishers, carpenters and other users with superior performance for applications such as polishing, sanding in-between two coatings and fine sanding of solid surfaces.
