Norton 66243522418 Surface Grinding Wheel 24 Grit 3 in

Product Description

The NORTON 66243522418 is a Type 1 surface grinding wheel designed for aggressive stock removal on a wide range of ferrous and non-ferrous materials. Built with aluminum oxide abrasive and a resinoid bond, it operates at a maximum of 12,100 RPM and delivers a very coarse, 24-grit cut suited for rapid material reduction rather than fine finishing. At 3 inches in diameter, 0.5 inches thick, and with a 3/8-inch arbor hole, it mounts directly to compatible bench-mounted or inline grinding equipment. Licensed trade professionals and maintenance machinists rely on this wheel for heavy grinding tasks where surface finish is secondary to material removal rate.

This wheel is rated for use on 300 series and 400 series stainless steel, hard and soft carbon steels, tool steels, titanium, super alloys, aluminum, brass, bronze, copper, cast iron, ductile iron, and gray iron. It is intended for use with flexible shaft grinders and ID grinders. The non-porous, resinoid-bonded construction handles the heat and mechanical stress typical of these demanding grinding applications without glazing prematurely.

Key Features

• Aluminum oxide abrasive for broad ferrous and non-ferrous material compatibility
• 24-grit, very coarse grade for fast stock removal
• Resinoid bond resists heat buildup and maintains wheel integrity at speed
• 12,100 RPM maximum rated speed for flexible shaft and ID grinder use
• Non-porous, non-tapered Type 1 form with no recess for straightforward mounting
• Hardness code R provides firm but controlled cut on a wide range of workpiece hardness levels

Compatibility

Designed for use with flexible shaft grinders and ID grinders. Compatible material applications include 300 and 400 series stainless steel, hard and soft carbon steels, tool steels, titanium, super alloys, aluminum, brass, bronze, copper, cast iron, ductile iron, and gray iron.

Installation Notes

Installation should be performed by a qualified machinist or maintenance technician familiar with abrasive wheel safety standards. Always confirm the spindle RPM rating does not exceed the wheel maximum of 12,100 RPM before mounting. Inspect the wheel for cracks or chips before each use and perform a ring test per ANSI B7.1 guidelines. Never force the wheel onto the arbor or use an adapter that alters the 3/8-inch bore fit.
