Forney Industries 71978 Quick Change Flap Disc 36 Grit

Product Description

The Forney Industries 71978 is a 2-inch quick change flap disc designed for aggressive material removal on metal surfaces. Running at 36 grit, this disc cuts fast and handles heavy grinding, weld blending, and surface prep where coarser abrasive action is needed. It mounts to quick change backing systems, allowing fast disc swaps without tools during production grinding operations. Each package contains 6 discs. Licensed tradespeople and fabricators working in metal shops, welding environments, and structural steel applications rely on this type of disc for consistent, repeatable stock removal.

This flap disc is suited for use on mild steel, stainless steel, and similar ferrous metals in both shop and field settings. It fits applications in residential and commercial fabrication, maintenance welding, and structural ironwork. The 2-inch diameter makes it compatible with die grinders and right-angle tools that accept quick change accessories. The 36-grit designation puts it in the aggressive range, making it most effective for initial weld dressing, heavy burr removal, and scale elimination before finer finishing steps.
