Merit Abrasives 69957339737 Flap Wheel 40 Grit 3x1 in

Product Description

The MERIT ABRASIVES 69957339737 is a ceramic alumina unmounted flap wheel designed for aggressive material removal on metal and other hard surfaces. With a 40-grit coarse grade, this wheel delivers fast stock removal on welds, burrs, and surface imperfections. The coated abrasive construction uses a cloth backing with X-weight backing material, providing durability and flexibility through contoured and flat surface work. Rated to 20,000 maximum RPM, it is suited for use on high-speed die grinders and bench-mounted spindles. A 1/4-20 threaded center hole allows secure mounting without additional hardware.

This flap wheel is intended for metal fabrication, weld blending, deburring, and surface conditioning tasks common in industrial, mechanical, and trade shop environments. Its 3-inch outside diameter and 1-inch face width make it a compact, high-speed option for work in tight areas or on curved profiles. Licensed machinists, pipefitters, welders, and maintenance technicians are the typical installers and operators. It ships in a package quantity of one, making it practical for single-task procurement or replacement use.
