Utilizing a foam-backed construction and a multi-hole dust extraction system, this sanding disc provides uniform sanding results on both flat and contoured surfaces.
It is a well known product in automotive refinishing, woodworking, metal surface preparation and electronics manufacturing, providing a good compromise between cutting performance and surface quality.
Key Features
Flexible Foam Backing for Even Sanding
A built-in foam layer ensures even pressure distribution across the surface to reduce the risk of over-sanding, edge burn-through, and deep scratches. Ideal for curved and
Multi-Hole Dust Extraction Design
The precision perforated surface allows efficient dust removal when used with vacuum systems, improving sanding visibility and reducing clogging during operation.
Consistent Surface Finish
Designed for fine sanding and intermediate finishing, the disc produces a uniform scratch pattern, preparing surfaces for coating, painting, or polishing.
Anti-Clogging Performance
Open structure combined with dust extraction minimizes material build-up, ensuring stable cutting performance and longer service life.
Quick Attachment System
Hook and loop backing allows fast disc changes, improving productivity in industrial and workshop environments.
