Norton 63642502672 Flap Wheel 80 Grit 3.5x2 in Aluminum Oxide

Product Description

The NORTON 63642502672 is a coated abrasive unmounted flap wheel designed for deburring, blending, and surface finishing on metal and other hard materials. Built with aluminum oxide abrasive, it delivers consistent stock removal at a medium grade (80 grit) across a wide range of grinding and finishing tasks. The wheel measures 3.5 inches in outside diameter by 2 inches wide, with a 5/8-inch center hole for mounting to compatible arbors and spindles. Rated to a maximum of 12,000 RPM, it is suited for use with angle grinders, die grinders, and bench-mounted spindle units. No interleaf construction keeps the abrasive face aggressive and open throughout the wheel's service life.

This flap wheel is used in metal fabrication shops, welding operations, pipe finishing, and general surface prep applications. It is a practical choice for blending weld seams, removing mill scale, or finishing curved and contoured surfaces where flat abrasive discs cannot conform to the workpiece geometry. Sold individually, it fits shops that need single-unit replacement stock without committing to bulk quantities.

Installation Notes

Mounting and tool setup should be performed by a qualified operator familiar with abrasive wheel safety. Always verify the tool spindle speed does not exceed the 12,000 RPM maximum rating stamped on the wheel before mounting. Power down and disconnect the grinder or spindle tool completely before installing or removing the wheel. Follow ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels during installation and operation.
