Norton 63642502643 Mounted Flap Wheel 80 Grit 0.5 Inch

Product Description

The NORTON 63642502643 is a threaded-mount flap wheel designed for surface blending, deburring, and finishing on metal and other hard materials. The wheel uses aluminum oxide abrasive bonded to a cloth backing in an open-flap configuration, delivering consistent stock removal at medium grade with 80 grit. The threaded mount allows direct installation on die grinders and rotary tools without additional arbors. Rated to a maximum of 23,000 RPM, this wheel suits high-speed rotary applications where control and finish quality matter. The 0.5-inch face width targets tight contours, inside radii, and narrow channel work.

This mounted flap wheel is suited for metalworking applications in fabrication, maintenance, and repair environments. Its compact 0.5-inch face width makes it well-matched for bore work, tube interiors, and areas where a larger wheel cannot reach. Medium-grade 80 grit provides a balance between material removal rate and surface finish, making it a practical choice for blending welds, removing scale, or cleaning up machined edges. Typical users include machinists, pipefitters, and maintenance technicians working with ferrous and non-ferrous metals.

Key Features

• Aluminum oxide abrasive on cloth backing for durable, consistent cutting action
• 80 grit medium grade balances stock removal with surface finish quality
• Threaded mount for direct installation on standard die grinders and rotary tools
• 23,000 maximum RPM rating suits high-speed rotary tool applications
• 0.5-inch face width designed for narrow, confined, and contoured work areas
• No interleaf construction for straightforward flap contact and even wear

Compatibility

Designed as an OEM-style replacement or standard consumable for threaded-spindle die grinders and rotary tools accepting mounted abrasive flap wheels.

Installation Notes

Installation is performed by machinists or maintenance technicians using a standard die grinder with a compatible threaded spindle. Ensure the tool spindle speed does not exceed the 23,000 RPM maximum rating marked on the wheel before operation. Power down and disconnect the grinder from its air or electrical supply before mounting or removing the wheel. Inspect the flap wheel for damage before each use and never use a visibly torn or delaminated wheel.
