Pferd 47801409 Mounted Flap Wheel 40 Grit 3 in Aluminum Oxide

Product Description

The PFERD 47801409 is a mounted flap wheel designed for surface finishing, blending, and deburring with a straight grinder. It measures 3 inches in outside diameter with a 1 inch face width and uses a 1/4 inch shank for secure tool mounting. The abrasive is 40 grit aluminum oxide on a cloth backing, placing it in the coarse grade range. This combination delivers aggressive material removal on a wide range of ferrous and non-ferrous metals. Rated to 20,000 RPM, it suits high-speed inline grinder work in fabrication shops, maintenance environments, and production finishing operations. Licensed tradespeople and skilled fabricators are the primary installers.

This flap wheel is built for use with straight grinders and handles a broad range of material applications including steel, stainless steel, cast steel, aluminum, brass, copper, annealed cast iron, nodular cast iron, heat treatable steel, and non-ferrous metals. The coarse 40 grit rating makes it well suited to initial stock removal, weld blending, and surface prep work before finer finishing steps. It fits applications in both shop and field environments where consistent, controlled abrasion across contoured or flat surfaces is required.

Installation Notes

Installation is performed by machinists, fabricators, or maintenance technicians using a straight grinder with a compatible 1/4 inch collet.
