Tru-maxx 66253291597 Mounted Point 60 Grit B111 Aluminum Oxide

Product Description

The TRU-MAXX 66253291597 is an aluminum oxide mounted point abrasive designed for precision grinding, deburring, and surface finishing of metal workpieces. Configured in the B111 inverted cone radius end shape, it delivers consistent material removal in contoured areas, slots, and hard-to-reach internal surfaces. At 60 grit with a medium grade, it balances stock removal speed with surface finish quality. The 1/8 inch shank diameter fits standard die grinders and rotary tools, and the part weighs 0.02 pounds. With a maximum rating of 61,320 RPM, it is suited for high-speed applications where control and consistency matter.

This mounted point is used in metalworking, fabrication, and maintenance environments where a rotary abrasive tool is needed to work inside bores, cavities, or contoured profiles. Common applications include weld blending, port work, mold finishing, and casting cleanup. The inverted cone radius end geometry allows access to interior radii and chamfers that flat or straight profiles cannot reach effectively. It is typically used by machinists, tool and die makers, maintenance technicians, and fabricators working on ferrous and non-ferrous metals.

Key Features

• B111 inverted cone radius end shape for interior and contoured surface access
• 60 grit medium grade for balanced stock removal and surface finish
• Aluminum oxide abrasive material suited for ferrous metals and general-purpose grinding
• 1/8 inch shank diameter for compatibility with standard die grinders and rotary tools
• 61,320 RPM maximum rating supports high-speed operation
• Blue color coding for quick grit and grade identification

Compatibility

Designed for use with die grinders and rotary tools accepting a 1/8 inch shank. Suitable for general-purpose grinding and finishing on metal surfaces where a B111 inverted cone radius end profile is required.

Installation Notes

Installation and use should be performed by qualified machinists or technicians familiar with rotary abrasive tooling. Always verify that the tool spindle speed does not exceed the 61,320 RPM maximum rating before operation. Secure the shank fully in the collet and inspect the mounted point for cracks or damage before each use. Wear appropriate eye protection and follow applicable ANSI safety standards for abrasive grinding tools.
