Tru-maxx 66253291540 Mounted Point 60 Grit Aluminum Oxide A23

Product Description

The TRU-MAXX 66253291540 is an aluminum oxide mounted point designed for precision grinding, deburring, and surface finishing on metal and ferrous workpieces. Shaped to the A23 inverted cone radius end profile, it reaches into contoured surfaces, bores, and cavities that flat wheels cannot access. The vitrified bond holds the 60-grit abrasive firmly, delivering consistent stock removal at medium grade. The 1/4-inch shank mounts directly into standard die grinders and rotary tools. Rated to 40,300 RPM, it suits high-speed handheld and bench-mounted applications. Machinists, tool-and-die workers, and maintenance technicians are the primary users of this type of abrasive point.

This mounted point is suited for internal grinding, weld cleanup, mold and die finishing, and deburring of cast or machined components. The A23 shape is commonly chosen when working inside small-diameter bores or along curved interior profiles where access is limited. At 60 grit medium grade, it removes material efficiently without the aggressive surface damage associated with coarser grits, making it appropriate for intermediate finishing steps in metalworking shops and maintenance facilities.

Key Features

• A23 inverted cone radius end shape for access to contoured bores and recesses
• 60 grit medium grade aluminum oxide abrasive for balanced stock removal and surface finish
• Vitrified bond for consistent abrasive exposure and long service life
• 1/4-inch shank diameter fits standard die grinder collets
• 40,300 RPM maximum speed rating for high-speed rotary tool use
• 1-inch head thickness provides substantial grinding surface for the A23 profile

Compatibility

Designed for use with die grinders and rotary tools accepting a 1/4-inch collet. Suitable for grinding aluminum oxide-compatible ferrous metals and alloys in standard shop and maintenance applications.

Installation Notes

Installation and use should be performed by machinists or maintenance technicians familiar with abrasive tooling safety. Confirm the spindle speed of the grinder does not exceed the 40,300 RPM maximum before mounting. Inspect the mounted point for cracks or chips before each use and discard any damaged point immediately. Always use appropriate eye protection and guarding per ANSI B7.1 safety standards for abrasive products.
