Merit Abrasives 69957339701 Mounted Flap Wheel 40 Grit

Product Description

The MERIT ABRASIVES 69957339701 is a ceramic alumina mounted flap wheel designed for aggressive material removal on metal and other hard surfaces. It features a 1-inch diameter with a 1-inch face width, runs on a 1/4-inch shank, and is rated to 30,000 RPM. The 40-grit coarse grade makes it well-suited for deburring, blending, and surface conditioning in tight or contoured areas. The cloth backing with X-weight construction provides durability and flexibility during use. This wheel is installed and operated by machinists, tool and die workers, metal fabricators, and maintenance technicians working with die grinders or rotary tools.

This mounted flap wheel is used in applications requiring aggressive stock removal or surface prep in confined spaces, such as weld cleanup, deburring bores, or blending inside radii. The coated ceramic alumina abrasive delivers consistent cut rates across steel, stainless steel, and other hard metals. It mounts via a 1/4-inch shank, making it compatible with standard die grinders and flexible-shaft machines commonly found in fabrication shops and maintenance environments.
