Norton 63642502625 Mounted Flap Wheel 80 Grit Aluminum Oxide

Product Description

The NORTON 63642502625 is a mounted flap wheel abrasive designed for precision grinding, blending, and finishing on metal and other hard surfaces. Built with aluminum oxide grain on a cloth backing, this coated abrasive delivers consistent stock removal and surface conditioning across contoured and hard-to-reach areas. At 80 grit, it falls in the medium grade range, making it well suited for deburring, light material removal, and surface prep before coating or welding. It mounts via a threaded spindle and runs at up to 30,000 RPM, making it compatible with standard die grinders and rotary tools used in shop and field environments.

This mounted flap wheel is used in metalworking, fabrication, and maintenance applications where a standard flat grinding wheel cannot reach. Common tasks include internal bore finishing, weld blending inside tubing, and contour work on machined parts. It is sized at 1 inch in diameter with a 5/8 inch face width, making it effective in tight clearances. Machinists, fabricators, and maintenance technicians are the primary users. It is sold individually and is appropriate for both bench-mounted rotary tools and handheld die grinders.

Key Features

Compatibility

Designed as an OEM-style replacement or standard-use mounted flap wheel for die grinders and rotary tools accepting a threaded spindle mount with a 1 inch diameter abrasive head.

Installation Notes

Installation is performed by machinists or fabricators familiar with rotary abrasive tooling. Before mounting, confirm the tool spindle thread matches the wheel mount and verify the tool RPM rating does not exceed the wheel maximum of 30,000 RPM. Always power down and disconnect the tool before mounting or removing the wheel. Wear appropriate eye and face protection per ANSI B11 and OSHA abrasive wheel standards when operating.
