KLINGSPOR abrasive self-adhesive sanding discs PS21FK, 150 mm diameter, grit 80, pack of 50 are designed for manual and machine sanding of wood, painted and varnished surfaces as well as metal. The self-adhesive backing enables quick attachment and replacement on sanding pads and rotary tools, supporting efficient workflow in workshops and renovation jobs. This abrasive is intended for surface preparation, smoothing, removal of old paint or varnish, and intermediate sanding steps.

Advantages

The 150 mm size fits common sanding pads and orbital tools while the self-adhesive system provides fast changeover and secure mounting during operation. Grit 80 offers a balance between cutting aggressiveness and surface control, making these discs suitable for both heavy stock removal and preparatory sanding. Supplied in a pack of 50, the set reduces downtime for replacements and is convenient for regular workshop use.

How to use

Attach the disc to a compatible 150 mm sanding pad or rotary tool using the self-adhesive backing, ensuring it is centered and securely pressed in place. Start sanding with moderate pressure and move the tool evenly across the surface to avoid gouging. For heavy material removal, maintain steady, overlapping passes; for finishing or between-coat sanding, use lighter pressure and check progress frequently. Replace discs when abrasive performance decreases or the backing becomes contaminated.

Usage recommendations

For best results, use grit 80 PS21FK discs for initial stock removal and rough leveling, then progress to finer grits for smoothing and finishing. Wear appropriate personal protective equipment such as eye protection and a dust mask, and use dust extraction where possible to prolong abrasive life and maintain a safer work environment.
