- 1/2-inch unthreaded hole fits common arbors without adapters
3M Unitized Wheel Fine Grade
The 3M 13741 unitized wheel is a non-woven abrasive disc built for surface conditioning on metal. It suits fabricators and maintenance technicians who need consistent blending, cleaning or finishing without aggressive stock removal.
Silicon Carbide Soft Density Construction
The wheel uses silicon carbide grain in a soft density (2) structure rated Fine grade. This combination decides whether the part matches the application, delivering controlled cut and conformability on contoured or irregular surfaces.
5,000 RPM Maximum Operating Speed
Normal use stays within the 5,000 RPM limit, producing moderate heat and low vibration on compatible tools. The unthreaded 1/2 in hole mounts directly on standard arbors, and the gray non-woven construction resists loading during extended finishing passes.

Questions about this item
How does the 5,000 RPM maximum speed affect the finish when this wheel is mounted on a bench grinder?
Running at or below 5,000 RPM lets the soft density and fine-grade silicon carbide produce a consistent satin surface without gouging the workpiece.
What does the 1/2-inch unthreaded hole mean for mounting on my tool?
The 1/2-inch unthreaded hole slides onto a matching arbor or mandrel and is secured with a flange and nut supplied by the grinder.
Will the 6-inch diameter and 1/4-inch face width fit my standard bench grinder guards?
The 6-inch diameter matches common bench grinder wheels; the 1/4-inch face is narrower than standard wheels so existing guards usually clear it.
