Abrasive Hook-and-Loop Disc KLINGSPOR PS21FK 150 mm Grit 40 Pack of 50 (MPN 230312)

Klingspor PS21FK hook-and-loop abrasive discs, 150 mm diameter, grit 40, are designed for fast material removal and coarse sanding on wood, metal and painted surfaces. The open-coat abrasive grain and robust backing provide consistent stock removal while maintaining disc life under heavy-duty use. The hook-and-loop fastening allows quick disc changes on compatible orbital and rotary sanders, reducing downtime during furniture work, renovation and metal preparation.

Advantages

The abrasive discs combine coarse grit with an open coating that resists loading and improves performance when sanding painted or resinous surfaces. The durable backing ensures stable contact with the workpiece and supports aggressive sanding without premature tearing. Hook-and-loop attachment simplifies replacement and keeps the abrasive flat on the sander for even material removal.

Suitable for

• Rapid stock removal on raw and seasoned wood
• Removing paint, rust and corrosion from metal surfaces
• Surface preparation before priming or refinishing
• Coarse sanding in furniture restoration and renovation projects
• Use with compatible 150 mm orbital and rotary sanders

Key specifications

• Disc diameter: 150 mm
• Abrasion grade: 40 (coarse)
• Attachment type: hook-and-loop backing for quick change
• Pack quantity: 50 discs
• Suitable substrates: wood, metal, painted surfaces

How to use

Fit a disc to a compatible 150 mm orbital or rotary sander by aligning the hook-and-loop surfaces and pressing firmly to ensure full contact. Start sanding at low speed to establish control, then increase speed as appropriate for the material and task. Apply even pressure and move the sander continuously to avoid gouging; allow the abrasive to do the work rather than forcing excessive force. Replace discs when abrasive performance drops or the backing becomes damaged.

Usage recommendations

For prolonged disc life and consistent results, avoid clogging by cleaning the abrasive with a rubber cleaning stick when sanding paint or resinous woods. Use appropriate personal protective equipment—dust mask, eye protection and hearing protection—and ensure dust extraction or good ventilation when working on metal or painted surfaces.
