Norton 63642502644 Mounted Flap Wheel 120 Grit Fine

Product Description

The NORTON 63642502644 is a mounted flap wheel abrasive designed for precision grinding, blending, and finishing on metal and other hard surfaces. It uses an aluminum oxide coated abrasive on a cloth backing, rated at 120 grit for fine material removal and surface refinement. With a face width of 0.5 inches and a threaded mount, this wheel installs directly onto compatible rotary tools and die grinders. It is rated to a maximum of 23,000 RPM, making it suitable for high-speed finishing work in fabrication, maintenance, and repair applications. Trade professionals rely on this format for accessing tight radii, contoured surfaces, and internal bores where larger tooling cannot reach.

This mounted flap wheel is used in metalworking, welding cleanup, and surface prep tasks across manufacturing, HVAC sheet metal work, plumbing fabrication shops, and general mechanical trades. The fine 120-grit aluminum oxide construction is well suited for blending weld seams, removing light burrs, and preparing surfaces for coating or inspection. Its compact 0.5-inch face width makes it effective in confined areas and on smaller workpieces where control and precision matter more than aggressive stock removal.

Compatibility

Designed as an OEM-style replacement or standard aftermarket option for use with threaded-arbor rotary tools and die grinders rated to handle the 23,000 RPM maximum speed of this wheel.

Installation Notes

This wheel is installed by a machinist, fabricator, or trade technician onto a compatible threaded-arbor rotary tool or die grinder. Always confirm the tool spindle speed does not exceed the 23,000 RPM maximum rating before operation. Inspect the wheel for damage before each use and discard any wheel showing tears, missing flaps, or delamination. Follow ANSI B7.1 and applicable shop safety guidelines when mounting and operating abrasive wheels.
