Arc Abrasives 10816AF Flap Disc Type 29 80 Grit 4.5 in

Product Description

The ARC ABRASIVES 10816AF is a Type 29 flap disc designed for general-purpose grinding and blending on metal and composite surfaces. Measuring 4.5 inches in diameter with a 5/8 inches-11 threaded hub, it fits standard right-angle grinders used daily in fabrication, welding, and construction trades. The 80-grit aluminum oxide abrasive removes material efficiently while leaving a workable surface finish. Cotton backing reinforces each abrasive flap, adding structural strength and extending disc life under sustained load. This disc is a practical choice for metalworkers, welders, and maintenance technicians who need a dependable general-purpose disc at a competitive value.

The 10816AF is suited for use on mild steel, aluminum, and composite materials. Its Type 29 conical profile positions the abrasive at an angle to the workpiece, concentrating cutting pressure and making it effective for aggressive stock removal on flat and contoured surfaces. Typical applications include weld blending, surface prep before coating, deburring, and edge cleanup in both shop and field environments. The 5/8 inches-11 arbor is the standard thread size for most 4.5-inch angle grinders available to trade professionals.
