Arc Abrasives 71-10823AF Flap Disc Type 29 36 Grit 10 Pack

Product Description

The ARC ABRASIVES 71-10823AF is a Type 29 angled flap disc designed for aggressive grinding and blending on metal surfaces. Measuring 4-1/2 inches in diameter with a 7/8-inch arbor hole, this disc uses a proprietary grain mix that delivers faster material removal compared to standard abrasive grains. The conical Type 29 profile concentrates cutting action at the disc edge, making it well-suited for weld blending, deburring, and surface conditioning on structural steel, fabricated components, and pipe. Each pack contains 10 discs. The 36 grit rating places this disc in the coarse range, optimized for stock removal rather than finishing work.

This flap disc is used in fabrication shops, welding operations, pipeline work, and general metalworking applications where fast cutting and extended disc life are priorities. The Type 29 geometry is particularly effective on flat stock and slightly contoured surfaces where a tilted grinding angle improves contact. At 36 grit, it is appropriate for initial weld cleanup, scale removal, and heavy stock removal before transitioning to finer finishing steps. The proprietary grain mix is rated for 2 to 3 times the flap life of conventional abrasive flap discs, reducing disc changes during extended work sessions.

Key Features

• Type 29 conical profile for angled grinding and weld blending
• 4-1/2 inch diameter with 7/8-inch arbor for standard right-angle grinder compatibility
• 36 grit coarse rating for aggressive stock removal and weld cleanup
• Proprietary grain mix rated for 2 to 3 times the flap life of standard abrasive discs

Compatibility

Designed for use on right-angle grinders accepting 4-1/2 inch discs with a 7/8-inch arbor. Suitable for grinding and blending carbon steel, stainless steel, and other ferrous metals.

Installation Notes

Flap discs are installed and replaced by metalworkers, fabricators, and welders using standard right-angle grinders. Always power down and disconnect the grinder before changing discs. Confirm the grinder RPM rating meets or exceeds the disc RPM rating before use. Wear appropriate PPE including a face shield, gloves, and hearing protection during operation.
