3 in Flap Wheel Fine Grade
This 3M flap wheel uses non-woven aluminum oxide abrasive in a fine grade for surface finishing and blending. The 3 inch diameter and 1.75 inch wide flaps suit detail work on metal and other materials. It mounts on a 1/4 inch unthreaded shank for direct fit in compatible power tools. Maximum operating speed is 8,500 RPM.
Best for light deburring and finishing
Metalworkers preparing surfaces for paint or coating will find the fine grade effective. Woodworkers needing aggressive stock removal should choose a coarser abrasive type. The non-woven construction resists loading but is not designed for heavy grinding or weld removal. Users requiring threaded mounting must select a different wheel.
1/4 inch unthreaded shank compatibility
The wheel fits tools with a 1/4 inch collet or chuck that accepts an unthreaded shank. Verify your tool's shank requirement before purchase as threaded arbors will not accept this wheel. The 8,500 RPM maximum speed must not be exceeded. Matching shank size and speed rating determines safe installation.
