Tru-maxx 66253291631 Mounted Point 60 Grit A21 Ball

Product Description

The TRU-MAXX 66253291631 is an aluminum oxide mounted point designed for precision grinding, deburring, and surface finishing on metal and other hard materials. It features an A21 ball shape, 60 grit medium grade abrasive, and a vitrified bond that delivers consistent stock removal and controlled cutting action. The 1/4 inch shank diameter fits standard die grinders and rotary tools commonly used by machinists, tool and die workers, and maintenance technicians. Rated to 34,500 RPM, this mounted point is built for high-speed rotary applications where a small, controllable abrasive contact point is required.

This mounted point is suited for internal grinding, cavity work, weld blending, and deburring operations in production and maintenance environments. The ball profile makes it effective for contouring curved or recessed surfaces that flat or cylindrical points cannot reach. It is a standard choice in metal fabrication shops, toolrooms, and general industrial maintenance settings where die grinders are part of routine workflow.

Key Features

• A21 ball shape for contouring and internal surface work
• 60 grit medium grade for balanced stock removal and surface finish
• Aluminum oxide abrasive material suited for ferrous metals and general-purpose grinding
• Vitrified bond for consistent grain exposure and cutting performance
• 1/4 inch shank diameter fits standard die grinder collets
• Rated to 34,500 RPM for high-speed rotary tool use

Compatibility

Designed for use with die grinders and rotary tools accepting a 1/4 inch shank collet. Suitable for general-purpose grinding and finishing of ferrous metals and similar hard materials.

Installation Notes

Mounted points should be installed by a qualified operator familiar with abrasive tool safety. Always verify that the tool spindle speed does not exceed the 34,500 RPM rating marked for this point before use. Inspect the mounted point for cracks or chips before mounting, and ensure the shank is fully seated and secured in the collet. ANSI B11 and OSHA abrasive wheel safety guidelines apply to mounted point use in industrial settings.
