Arc Abrasives 71-10814AF Flap Disc Type 29 40 Grit 4.5in

Product Description

The ARC ABRASIVES 71-10814AF is a Type 29 flap disc designed for general-purpose grinding and blending on angle grinders. Measuring 4.5 inches in diameter with a 5/8 inches-11 threaded hub, it runs a 40-grit abrasive cloth layered over a cotton backing for added strength and durability. The Type 29 conical geometry presents the abrasive at an angle, making it effective for aggressive material removal on flat and contoured surfaces. Fabricators, welders, and metalworkers use this disc for weld blending, surface conditioning, and edge work across a range of base materials.

This flap disc is suited for use on mild steel, aluminum, and composite materials in both shop and field applications. The 40-grit designation places it in the coarse range, making it a practical choice for fast stock removal, rust and scale cleanup, and initial weld seam grinding. It fits standard 4.5-inch angle grinders with a 5/8 inches-11 spindle, which covers a wide range of professional-grade tools found on fabrication floors and job sites.
