Norton 63642502668 Flap Wheel 60 Grit 3.5x1 in Aluminum Oxide

Product Description

The NORTON 63642502668 is a coated abrasive unmounted flap wheel designed for grinding, blending, and finishing on metal, wood, and composite surfaces. Built with aluminum oxide abrasive bonded to a cloth backing, this medium-grade wheel delivers consistent stock removal at 60 grit. It measures 3.5 inches in outside diameter by 1 inch wide, with a 5/8-inch center hole for mounting on arbors and spindles. The wheel is rated to a maximum of 12,000 RPM. No interleaf material is used, keeping the construction straightforward and predictable throughout the life of the wheel. Machinists, fabricators, metal finishers, and maintenance techs are the typical users.

This flap wheel suits portable die grinders, bench-mounted spindles, and drill press setups where controlled surface finishing or edge blending is needed. At 3.5 inches diameter and 1 inch face width, it fits contouring work on curved or irregular profiles where flat abrasive discs cannot conform. The 60-grit medium grade makes it appropriate for initial surface prep, weld blending, and deburring on ferrous and non-ferrous metals, as well as hardwood and fiberglass. It is sold individually with a minimum order quantity of one unit.

Installation Notes

Always verify the spindle or arbor speed rating meets or exceeds 12,000 RPM before mounting this wheel. Secure the wheel firmly on the arbor with the appropriate flange and nut before powering the tool. Inspect the wheel for cracks or damage before each use and do not exceed the rated maximum RPM under any circumstances. Use appropriate eye protection and guarding per ANSI B7 standards when operating rotating abrasives.
