Arc Abrasives 71-10816AF Flap Disc Type 29 80 Grit 4-1/2 in

Product Description

The ARC ABRASIVES 71-10816AF is a Type 29 flap disc designed for general-purpose grinding and blending on metal and composite surfaces. Measuring 4-1/2 inches in diameter with a 5/8 inches-11 threaded hub, it mounts directly to standard angle grinders. The 80-grit aluminum oxide abrasive delivers a balance of stock removal and surface finish suited to production and field work alike. Cotton backing reinforces each flap, adding structural rigidity and durability through the full life of the disc. Installers and fabricators in metalworking, HVAC fabrication, and structural trades will find this disc a reliable everyday tool.

This flap disc is built for use on mild steel, aluminum, and composite materials. The Type 29 conical angle is optimized for aggressive material removal on flat and contoured surfaces, making it well suited for weld blending, edge work, and surface preparation before coating or welding. It is commonly used in shop and field environments where a single disc needs to handle both grinding and finishing passes without swapping tooling.
