Tru-maxx 66253291894 Mounted Point 60 Grit B84 Aluminum Oxide

Product Description

The TRU-MAXX 66253291894 is an aluminum oxide mounted point in the inverted cone cupped end (B84) configuration, designed for precision grinding, deburring, and surface finishing on metal and other hard materials. With a 60-grit medium grade abrasive, it removes material efficiently while maintaining control on contoured and hard-to-reach surfaces. The shank diameter is 1/8 inch with a shank length of 1.5 inches, and the head thickness measures 3/16 inch. Rated to a maximum of 105,000 RPM, this mounted point is suited for use with high-speed die grinders and rotary tools in production, maintenance, and repair applications.

This mounted point is commonly used by machinists, tool-and-die workers, maintenance technicians, and fabricators working in metal finishing, weld cleanup, cavity grinding, and die work. The B84 inverted cone cupped end shape allows access to recessed areas, internal profiles, and complex geometries where flat or straight abrasives cannot reach effectively. It is appropriate for bench-top and handheld die grinder use in both shop and field environments.

Key Features

• 60-grit medium grade aluminum oxide abrasive for efficient stock removal
• Rated to 105,000 RPM for compatibility with high-speed die grinders
• 1/8 inch shank diameter fits standard die grinder and rotary tool collets
• 3/16 inch head thickness provides a defined contact profile for controlled grinding
• Pink aluminum oxide formulation suited for general-purpose ferrous metal grinding

Compatibility

Designed for use with die grinders and rotary tools accepting a 1/8 inch shank collet. Suitable for grinding ferrous metals, tool steel, and similar hard materials in standard shop and maintenance applications.

Installation Notes

This mounted point is installed by inserting the 1/8 inch shank into the collet of a compatible die grinder or rotary tool and tightening securely per the tool manufacturer's instructions. Always verify that the tool's operating RPM does not exceed the 105,000 RPM maximum rating of this abrasive before use. Wear appropriate eye protection and ensure the workpiece is properly secured before grinding. Inspect the mounted point for cracks or damage before each use and discard if any defects are found.
