Walter Surface Technologies 15F904 Mounted Flap Wheel 40 Grit

Product Description

The WALTER SURFACE TECHNOLOGIES 15F904 is a mounted flap wheel designed for aggressive stock removal and surface conditioning on metal workpieces. Built with aluminum oxide abrasive on a cloth backing, it delivers consistent cut and finish across the full 2-inch face width. The 40-grit coarse grade bites quickly into steel, stainless steel, and aluminum, making it a practical choice for weld blending, deburring, and edge work. The 1/4-inch shank mount allows direct installation in bench grinders and straight-shaft tools. Rated to 11,000 RPM, this wheel suits high-speed die grinder and bench grinder applications where controlled material removal is the priority.

This mounted flap wheel is used in fabrication, maintenance, and metalworking applications across residential and light industrial settings. It is suited for finishing operations on aluminum, stainless steel, and mild steel surfaces. Compatible with bench grinders and straight-shaft tools fitted with a 1/4-inch collet or chuck, it works well for operators who need a small-diameter wheel for contoured or recessed surfaces. Fabricators, pipefitters, and welders commonly reach for this wheel during weld prep and post-weld cleanup tasks.
