Abrasive flap discs KLINGSPOR 125 mm with holes, grit 120, pack of 5 (MPN 45297)

KLINGSPOR abrasive flap discs, 125 mm diameter with ventilation holes and grit 120, supplied in a pack of five. These discs are designed for grinding and finishing on metal surfaces, welded seams and for removing rust, paint and burrs. The multi-flap construction ensures even wear and stable cutting performance over the disc life. Discs fit standard 125 mm angle grinders and the ventilation holes help reduce heat build-up during prolonged work.

Advantages

The flap design combines overlapping abrasive flaps that wear progressively, providing consistent material removal and an extended service life compared with single-layer abrasive discs. Grit 120 offers a balance between stock removal and surface finish for medium-fine grinding tasks. Ventilation holes improve dust extraction and cooling, which reduces thermal damage to the workpiece and helps maintain abrasive performance. Pack of five ensures quick replacement and uninterrupted workflow.

Suitable for

• Grinding and blending of welded seams on steel and stainless steel
• Removal of rust, scale and old paint from metal surfaces
• Deburring and edge rounding on fabricated parts
• Surface preparation prior to painting or coating

Key specifications

• Disc diameter: 125 mm
• Abrasive grit: 120 (medium-fine)
• Construction: multi-layer flap (overlapping abrasive flaps)
• Ventilation: holes for reduced heat and improved dust extraction
• Pack size: 5 discs
• Compatibility: for use with 125 mm angle grinders

How to use

Mount the flap disc on a compatible 125 mm angle grinder following the tool manufacturer's instructions and ensure the grinder is unplugged or the battery removed during installation. Use appropriate personal protective equipment including eye protection, gloves and respiratory protection if necessary. Start grinding at a moderate angle and apply consistent, light pressure; allow the abrasive flaps to do the work rather than forcing the disc into the material. Maintain steady movement to avoid creating grooves or excessive heat. Replace the disc when wear reduces cutting performance or when the abrasive flaps are no longer effective.

Usage recommendations

For best results, use at the recommended speed range for 125 mm discs and pair with effective dust extraction when working on metal. Store discs in a dry, temperate environment away from direct sunlight and moisture to preserve abrasive properties. Choose grit 120 for a compromise between efficient material removal and a smoother finish; for heavier stock removal consider using a coarser grit, and for finer finishing choose a higher grit.
