Arc Abrasives 10856AF Flap Disc 7in Type 29 80 Grit

Product Description

The ARC ABRASIVES 10856AF is a Type 29 flap disc designed for general-purpose grinding and blending on mild steel, aluminum, and composite materials. Measuring 7 inches in diameter with a 5/8 inches-11 threaded hub, it mounts directly to standard angle grinders used in fabrication, welding cleanup, and surface prep work. The 80-grit aluminum oxide abrasive delivers a balance of stock removal and finish quality suited to everyday metalworking tasks. Cotton backing reinforces the disc under load, maintaining disc integrity during aggressive passes and extended use. Welders, fabricators, and metalworkers are the primary users of this disc.

This flap disc is well suited for light to medium material removal on mild steel weldments, aluminum sheet, and fiberglass or composite panels. The Type 29 conical profile presents the abrasive at an angle that concentrates cutting action, making it effective for blending welds, removing mill scale, and smoothing rough surfaces on flat and contoured workpieces. It is sold individually and is a practical consumable for shop and field metalworking environments.
