Abrasive Hook-and-Loop Disc KLINGSPOR PS21FK 150 mm Ø, P180, pack of 50 (MPN 252774)

KLINGSPOR PS21FK 150 mm Ø, P180 abrasive hook-and-loop discs are designed for general metalworking, paint and varnish removal, and surface preparation. Supplied in a pack of 50, each 150 mm disc is compatible with standard 150 mm backing pads and provides consistent cutting and finishing performance for both manual and machine sanding operations.

Advantages

The PS21FK abrasive combines a balanced cut rate with uniform grit distribution to deliver predictable material removal and an even surface finish. The hook-and-loop backing enables fast disc changes and secure attachment to standard backing pads. P180 grit offers medium-fine abrasion suitable for smoothing edges, removing light coatings, and preparing surfaces prior to painting or welding.

Suitable for

• Metal deburring and edge blending
• Removal of paint, varnish and corrosion
• Surface preparation before welding, priming or repainting
• Fine sanding and finishing on steel, stainless steel and non-ferrous metals

Key specifications

• Disc diameter: 150 mm
• Abrasion grit: P180 (medium-fine)
• Attachment: hook-and-loop (velcro) backing

How to use

Attach a KLINGSPOR PS21FK disc to a compatible 150 mm backing pad using the hook-and-loop fastening, ensuring the disc is centered and fully engaged with the pad. Operate the sander at the tool manufacturer’s recommended speed and apply steady, even pressure; avoid excessive force to prevent premature wear and uneven abrasion. For best results, move the sander in overlapping passes and check the surface frequently to monitor progress.

Usage recommendations

Wear appropriate personal protective equipment including safety glasses, hearing protection and a dust mask. Use dust extraction where possible when sanding metal or coated surfaces. Replace discs when the abrasive becomes glazed or loses effectiveness to maintain consistent surface quality.
