Abrasive Fibre Disc KLINGSPOR 125 mm K100 Zirconia Alumina, Pack of 25, MPN 204611

KLINGSPOR abrasive fibre disc, 125 mm diameter with K100 zirconia alumina grit, is designed for metal grinding, surface preparation and weld removal. Supplied as a pack of 25, the disc combines a high-cutting abrasive with a durable fibre backing to deliver consistent performance on angle grinders. The 125 mm size fits standard 5-inch grinders and common backing pads used in workshops and industrial environments.

Advantages

This abrasive fibre disc offers a balance of aggressive material removal and extended service life due to the zirconia alumina abrasive. The fibre backing ensures stability and resistance to tearing during heavy use, while the K100 grit provides effective grain size for smoothing and shaping metal surfaces. The discs are suitable for repeated use on welded joints and for preparing metal before painting or coating.

Suitable for

• Metal grinding and shaping
• Weld seam removal and blending
• Surface preparation before painting or coating
• Deburring and edge radiusing on steel and stainless steel
• General workshop and industrial abrasion tasks

Key specifications

• Disc diameter: 125 mm
• Abrasive type: zirconia alumina
• Grit size: K100
• Backing material: fibre (felt/pressed fibre backing)
• Pack quantity: 25 discs
• Intended tool: angle grinder (125 mm / 5-inch)

How to use

Attach the disc to a compatible 125 mm angle grinder and secure it with an appropriate backing pad according to the grinder manufacturer’s instructions. Operate the grinder at the recommended speed for abrasive fibre discs and apply light to moderate pressure, keeping the disc flat on the workpiece when appropriate to avoid gouging. Use steady, overlapping passes for even material removal and allow the disc to do the cutting rather than forcing it. Replace discs when the abrasive becomes worn or the backing shows damage.

Usage recommendations

Wear appropriate personal protective equipment, including eye and hearing protection, gloves and a dust mask or respirator when grinding. Ensure the workpiece is securely clamped and check the disc for damage before use. Use suitable coolant or intermittent grinding to avoid overheating heat-sensitive materials. Store discs in a dry, clean environment to preserve performance.
