Arc Abrasives 71-10826AF Flap Disc Type 29 80 Grit

Product Description

The ARC ABRASIVES 71-10826AF is a Type 29 flap disc designed for general-purpose grinding and blending on mild steel, aluminum, and composite materials. Measuring 4.5 inches in diameter with a 0.875-inch arbor hole, this disc runs at an 80 grit rating — a medium-coarse abrasive that removes material efficiently while leaving a workable surface finish. The cotton backing provides structural integrity under load, extending disc life in demanding shop and field applications. It is a standard consumable used by metalworkers, fabricators, and maintenance technicians across light industrial and construction trades.

This flap disc suits angle grinder work on flat and contoured surfaces. The Type 29 conical profile presents the abrasive at an angle to the workpiece, making it well-suited for blending welds, removing mill scale, and surface preparation on mild steel and aluminum. The 80 grit designation positions it between aggressive stock removal and finish work, covering a wide range of prep and cleanup tasks. Cotton-backed construction maintains consistent abrasive contact as the disc wears, supporting even material removal throughout the disc's service life.

Installation Notes

Installation and disc changes should be performed by the equipment operator with the grinder fully powered down and unplugged. Inspect the disc for damage before mounting and confirm the arbor size matches before securing. Always follow angle grinder manufacturer guidelines and applicable ANSI B7.1 safety requirements for abrasive wheel mounting and guard use. Do not exceed the maximum RPM rating marked on the disc.
