Abrasive Hook-and-Loop Disc 125 mm, grit 36, KLINGSPOR PS 18 EK (270238)

The KLINGSPOR Abrasive Hook-and-Loop Disc PS 18 EK, 125 mm diameter, grit 36, is designed for medium to aggressive material removal on metal, wood and composite surfaces. The open-coat abrasive structure and coarse grit enable efficient stock removal while maintaining consistent cutting performance. The hook-and-loop backing ensures quick disc changes on standard 125 mm backing pads and orbital sanders with a compatible attachment system. This disc is intended for shaping, deburring and surface preparation prior to painting, welding or further finishing operations.

Advantages

The abrasive features a durable mineral abrasive grain and a flexible backing that provides even contact with curved and flat surfaces. Its coarse grit offers fast cutting action and good removal rates on rust, scale, paint overspray and excess weld material. The hook-and-loop fastening allows rapid replacement and repositioning, reducing downtime during sanding tasks. The disc is suitable for both handheld and machine sanding applications when used with the correct backing pad.

Suitable for

• Shaping and stock removal on steel, aluminium and other metals
• Removing paint, rust and scale from metal surfaces
• Deburring welded joints and chamfering edges
• Sanding rough timber and composite panels prior to finishing
• Surface preparation before painting, priming or bonding

Key specifications

• Diameter: 125 mm
• Grit size: 36 (coarse)
• Attachment type: hook-and-loop (loop on disc, hook on pad)
• Abrasive type: mineral abrasive grain on a flexible backing
• Application: medium to aggressive material removal

How to use

Fit the disc onto a compatible 125 mm hook-and-loop backing pad, ensuring the disc is aligned and fully engaged with the pad hooks. Start the sander at low speed to check balance and tool response, then increase to the recommended operating speed for your machine and material. Apply moderate, even pressure and move the sander steadily; avoid excessive force that can reduce disc life or cause heat build-up. Replace the disc when cutting performance noticeably declines or the abrasive surface is worn.

Usage recommendations

For best results, use with a backing pad rated for the sander’s RPM and match grit progression when preparing surfaces for finishing (e.g., follow grit 36 with finer grits as needed). Wear appropriate personal protective equipment including eye, ear and respiratory protection when sanding metal or coated surfaces. Clean workpieces of loose debris before sanding to extend disc life and maintain consistent performance.
