Tru-maxx B82-GB-16812-T Mounted Point 60 Grit 1/8 in Shank

Product Description

The TRU-MAXX B82-GB-16812-T is an aluminum oxide mounted point in an inverted cone cupped end (B82) configuration. It carries a 60-grit, medium-grade abrasive face measuring 1/4 inch thick, mounted on a 1/8-inch-diameter shank that is 1-1/2 inches long. The aluminum oxide abrasive is suited for grinding ferrous metals, tool steel, and hard alloys. This mounted point is rated to 76,390 RPM, making it compatible with standard die grinders and rotary tools used in metalworking, deburring, and surface prep applications. Machinists, tool-and-die workers, and maintenance technicians are the primary installers.

This mounted point is used for internal grinding, port work, weld cleanup, and precision deburring in both shop and field environments. The inverted cone cupped end geometry allows access to recessed areas, contoured bores, and irregular surfaces where flat or cylindrical wheels cannot reach. It fits standard 1/8-inch collet die grinders commonly found in machine shops, fabrication facilities, and maintenance departments. The blue aluminum oxide construction handles medium material removal on carbon steel, alloy steel, and cast iron.

Compatibility

Designed for use with die grinders and rotary tools equipped with a 1/8-inch collet. Suitable for grinding, deburring, and surface preparation on ferrous metals and hard alloys.

Installation Notes

Installation is performed by machinists or maintenance technicians using a standard die grinder with a 1/8-inch collet. Always confirm the tool spindle speed does not exceed the 76,390 RPM rating marked on the mounted point before operation. Inspect the point for cracks or chips before mounting, and ensure the collet is fully tightened before running. Use appropriate eye protection and follow applicable ANSI B11 or shop safety standards when operating grinding tools.
