Weiler 31344 Flap Disc 40 Grit Type 29 Zirconia Alumina

Product Description

The WEILER 31344 is a Type 29 zirconia alumina flap disc designed for aggressive material removal on steel. Part of the Wolverine series, this coated abrasive disc measures 4.5 inches in diameter with a 7/8-inch arbor hole and runs at a maximum of 13,000 RPM. The cloth-backed flap construction distributes grinding pressure evenly across the work surface, making it well-suited for coarse-grade stock removal. The phenolic-backed disc body resists flex under load, maintaining consistent contact angle. Installers and fabricators working with angle grinders will find this disc sized and rated for standard 4.5-inch tool heads.

The WEILER 31344 is used in metal fabrication, structural steel work, and light industrial maintenance applications. Its 40-grit coarse rating makes it a go-to choice for beveling weld joints and deburring cut edges on steel. The Type 29 conical profile positions the abrasive flaps at an angle that concentrates cutting action at the disc edge, improving performance on contoured and flat surfaces alike. This disc is sold individually but requires a minimum order of 10 units, making it appropriate for shop stock or job-site consumable restocking.

Installation Notes

This disc should be installed and operated by personnel familiar with angle grinder safety procedures. Always confirm the tool's rated RPM meets or exceeds the disc's 13,000 RPM maximum before mounting. Power down and disconnect the grinder before changing discs, and inspect the disc for cracks or damage prior to each use. Eye protection, gloves, and appropriate PPE are required when operating abrasive grinding discs.
