Abrasive hook-and-loop disc KLINGSPOR 150 mm PS33CK grit 40 GLS51 pack 100 (MPN 310531)

KLINGSPOR PS33CK hook-and-loop abrasive disc, 150 mm diameter, grit 40 (GLS51) in a pack of 100 is designed for medium-coarse sanding and efficient material removal on metal, wood and coated surfaces. The disc uses a hook-and-loop backing for quick attachment and removal on sanding backing pads and is compatible with angle grinders and rotary sanders that accept 150 mm hook-and-loop discs. The open-coat abrasive construction reduces clogging and maintains cutting performance during prolonged use.

Advantages

The KLINGSPOR PS33CK disc delivers a high removal rate while preserving surface quality due to its grit 40 abrasive grain. The hook-and-loop fastening enables fast and tool-free disc changes, increasing productivity in industrial and workshop environments. The 150 mm diameter provides a balance between coverage and maneuverability, and the open-coat structure helps extend disc life by reducing loading when working on resins or painted surfaces.

Suitable for

• Removing rust, scale and welding seams from metal

How to use

Fit the 150 mm KLINGSPOR PS33CK disc onto a matching hook-and-loop backing pad, ensuring it is centered for safe rotation. Use appropriate rotational speed as recommended by the tool manufacturer and maintain stable, even pressure while sanding to avoid gouging. Periodically check the disc for wear and replace when performance decreases. Always use correct personal protective equipment and follow the safety guidelines of the angle grinder or sander being used.

Usage recommendations

For optimal results on metal, start with a steady, light pass to remove surface contaminants, then increase pressure for material removal. On wood and coatings, monitor dust loading and change discs when cutting becomes less aggressive. Combine with dust extraction where possible and select compatible backing pads to ensure secure attachment and even wear.
