Tru-maxx 66253291865 Mounted Point 60 Grit B63

Product Description

The TRU-MAXX 66253291865 is an aluminum oxide mounted point in the B63 wheel radius edge shape, designed for precision grinding, deburring, and surface finishing in tight or contoured areas. At 60 grit with a medium grade, it removes material efficiently while leaving a controlled surface finish. The 3/16 inch head thickness and 1/8 inch shank diameter make it suited for use in rotary tools, die grinders, and high-speed spindles. Rated to 81,370 RPM, this mounted point handles demanding applications without compromising safety margins. The pink aluminum oxide abrasive is a well-established grain for grinding ferrous metals and tool steel.

This mounted point is used in metal fabrication shops, maintenance facilities, and toolrooms where internal grinding, weld cleanup, porting, and deburring of hard-to-reach surfaces are routine tasks. The 1/8 inch shank fits standard die grinder chucks and rotary tool collets widely used in these environments. At 3/16 inch thick and with a 1-1/2 inch shank length, it provides good reach into bores, slots, and cavities. Machinists, tool and die makers, and maintenance technicians are the primary users of this type of mounted point.

Installation Notes

A licensed or experienced metalworking technician should mount this point in a die grinder or rotary tool with the appropriate 1/8 inch collet, ensuring the shank is fully seated before tightening. Always confirm the tool RPM rating does not exceed the 81,370 RPM maximum marked for this abrasive. Wear ANSI-rated eye protection and appropriate PPE when operating mounted abrasive points. Inspect the mounted point for chips or cracks before each use and discard any damaged piece immediately.
