Tru-maxx 66253291693 Mounted Point 60 Grit A3 Tree 1/4 in Shank

Product Description

The TRU-MAXX 66253291693 is an aluminum oxide mounted point designed for precision grinding, deburring, and surface finishing in hard-to-reach areas. This A3 tree-shaped point features a vitrified bond with 60 grit and a medium grade, making it well-suited for moderate material removal on ferrous metals and hard alloys. The 1/4 inch shank diameter mounts directly into standard die grinders and rotary tools. At a maximum operating speed of 15,530 RPM, it delivers consistent abrasive action without glazing. The brown aluminum oxide construction provides durable cutting performance across a wide range of grinding applications encountered in maintenance, toolroom, and fabrication environments.

This mounted point is used in toolroom grinding, weld cleanup, mold and die work, and general metalworking applications where a standard grinding wheel cannot access the workpiece geometry. The A3 tree profile allows entry into contoured surfaces, cavities, and irregular profiles. It is typically installed and operated by machinists, tool and die makers, maintenance technicians, and metalworking professionals using die grinders or flexible shaft machines.

Key Features

• A3 tree point shape for access to contoured and recessed surfaces
• 60 grit medium grade for balanced material removal and surface finish
• Aluminum oxide abrasive with vitrified bond for consistent, durable cutting action
• 1/4 inch shank diameter fits standard die grinders and rotary tool collets
• Rated to 15,530 RPM for use with common pneumatic and electric die grinders
• Lightweight at 0.02 pounds per piece for reduced operator fatigue during extended use

Compatibility

Designed as a standard OEM-style replacement or stock mounted point for use in die grinders and rotary tools accepting a 1/4 inch shank collet.

Installation Notes

Mounted points must be installed and operated by personnel familiar with abrasive tooling safety. Before mounting, verify the spindle speed of the grinder does not exceed the maximum RPM marked on the point. Tighten the collet securely to the shank and inspect the point for cracks or chips before each use. Never exceed the rated maximum operating speed, and always wear appropriate eye protection per applicable workplace safety standards.
