Abrasive unitized wheel for surface finishing

This 3M unitized wheel uses aluminum oxide abrasive in a non-woven construction. It measures three inches in overall diameter with a quarter-inch face width. The wheel carries a medium density rating of six and a medium grade for consistent surface conditioning. Maximum operating speed is eighteen thousand one hundred revolutions per minute.

Suited for deburring and blending on metal

The unthreaded three-eighths inch hole fits compatible mandrels on straight grinders or bench motors. Medium density resists loading while delivering uniform finishes on aluminum, stainless steel and similar materials. Not intended for heavy stock removal or aggressive grinding where a bonded wheel would be required.

18,100 RPM maximum operating speed

Exceeding this speed can cause wheel disintegration and serious injury. Always verify that the power tool’s no-load RPM is at or below the rated limit before mounting. The fixed speed rating is the single figure that determines whether the wheel matches the tool.
