Forney Industries 71981 Quick Change Flap Disc 36 Grit

Product Description

The Forney Industries 71981 is a quick-change flap disc designed for aggressive material removal on metal surfaces. Rated at 36 grit, this disc delivers coarse abrasion suited for weld blending, rust removal, and heavy stock removal tasks. At 3 inches in diameter, it mounts to quick-change backing systems without the need for additional hardware or tools, reducing changeover time during production or field work. Licensed welders, fabricators, and pipefitters typically reach for this disc when fast, consistent surface prep is required before welding or coating.

This flap disc is appropriate for use in both fabrication shop environments and field repair applications. The 3-inch diameter suits work on tight joints, pipe welds, and confined surfaces where a full-size angle grinder disc would be impractical. It is sold in packages of 6 units, making it practical for contractors and tradespeople managing consumable inventory. Compatible with standard quick-change mandrels used on die grinders and right-angle tools commonly found in HVAC, plumbing, and structural fabrication workflows.
