Tru-maxx 66253291531 A4 Mounted Point 60 Grit Aluminum Oxide

Product Description

The TRU-MAXX 66253291531 is an aluminum oxide mounted point in A4 tree shape, designed for precision grinding, deburring, and surface finishing on metal workpieces. It runs at a maximum of 28,550 RPM and features a vitrified bond construction that holds the 60-grit abrasive firmly during aggressive stock removal. The 1/4-inch shank diameter fits standard die grinders and rotary tools. At medium grade, this mounted point delivers a balance of cut rate and surface finish suitable for general-purpose grinding tasks. Weighing approximately 0.02 pounds, it is a lightweight consumable used regularly in fabrication, toolroom, and maintenance grinding applications.

This mounted point is suited for use in metal fabrication shops, toolrooms, and maintenance environments where a die grinder or rotary tool is the primary driver. The A4 tree profile is commonly applied to contoured surfaces, inside radii, ports, and recessed areas that flat or cylindrical wheels cannot reach. It is typically installed and used by machinists, maintenance technicians, and metalworking professionals who require controlled material removal in tight geometries.

Key Features

• A4 tree point shape for access to contoured surfaces, inside radii, and recessed areas
• 60-grit medium grade provides a balance of aggressive stock removal and controlled surface finish
• Aluminum oxide abrasive material suited for grinding ferrous metals and general-purpose workpieces
• Vitrified bond holds abrasive grain firmly for consistent performance throughout wheel life
• Maximum rated speed of 28,550 RPM for use with standard die grinders and rotary tools
• 1/4-inch shank diameter fits widely available collets and chuck sizes

Compatibility

Designed for use with die grinders and rotary tools accepting a 1/4-inch shank. Verify that the tool spindle speed does not exceed the 28,550 RPM maximum rating before use.

Installation Notes

Mounted points must be installed by a qualified operator familiar with abrasive wheel safety. Always power down and disconnect the grinder before inserting or removing the shank from the collet. Confirm the tool maximum RPM rating meets or does not exceed the wheel maximum of 28,550 RPM prior to operation. Inspect the mounted point for cracks or damage before each use and never operate a damaged abrasive accessory.
