FEIN 63730022010 Flap Disc 125 mm P40 Zirconia Alumina 10-Pack

For professionals who demand aggressive stock removal without sacrificing longevity, the FEIN 63730022010 flap disc stands apart from conventional abrasives. Its P40 zirconia alumina grain is engineered for high-pressure grinding on steel and stainless steel, delivering a cut rate that rivals ceramic discs while maintaining a cooler grind. The 125 mm diameter and 22.23 mm bore fit standard angle grinders, and the flat Type 27 profile ensures full-face contact on flat surfaces. Each pack contains 10 discs, providing a cost-effective solution for continuous workshop use.

Highlights

• P40 zirconia alumina grain for fast, cool cutting on ferrous and non-ferrous metals
• Fiberglass backing plate resists deformation under heavy load
• Resin bonding system ensures even wear and long service life
• Flat Type 27 shape ideal for grinding, deburring, and surface finishing
• 10 discs per pack for reduced downtime and consistent inventory

In daily use

Mount the disc on a 125 mm angle grinder and tackle weld seams, bevels, or rust removal with confidence. The high initial aggressiveness reduces the need for multiple passes, while the controlled breakdown of the abrasive flaps exposes fresh grain continuously. Operators will notice less vibration and chatter compared to standard fiber discs, thanks to the rigid yet slightly flexible backing. The disc is certified to EN 13743, ensuring compliance with European safety standards for bonded abrasives.
