The NORTON 63642502678 is a coated abrasive unmounted flap wheel designed for surface finishing, blending, and deburring applications in metalworking and fabrication environments. Built with aluminum oxide abrasive on a cloth backing, this flap wheel measures 5 inches in outside diameter and 1 inch in face width with a 5/8-inch center hole for mounting to a spindle or arbor. It carries an 80-grit, medium-grade cut suited for stock removal and surface conditioning on ferrous and non-ferrous metals. Maximum rated speed is 6,200 RPM. This wheel is sold individually and installed by machinists, fabricators, and tool-and-die technicians.
This flap wheel is used in bench-mounted, pedestal, or portable spindle setups for finishing flat, contoured, and irregular metal surfaces. Its cloth backing provides conformability on curved workpieces, making it a practical choice for weld blending, edge breaking, and light deburring on structural components, tubing, and sheet metal. The medium-grade, 80-grit cut positions it as a mid-process step between heavy grinding and fine finishing work in production and repair environments alike.
Designed as a standard unmounted flap wheel for use with spindles or arbors accepting a 5/8-inch bore, common to bench-mounted and pedestal grinding or finishing machines.
Flap wheels of this type are mounted by machinists or fabricators onto a compatible spindle or arbor. Verify that the machine speed does not exceed the 6,200 RPM maximum rating before operation. Ensure the wheel is firmly secured and the machine is fully powered down before mounting or removing the wheel. Wear appropriate PPE including eye protection and gloves when operating abrasive tooling.
