Tru-maxx TM-GPB91O Mounted Point 60 Grit Aluminum Oxide B91

Product Description

The TRU-MAXX TM-GPB91O is an aluminum oxide mounted point designed for precision grinding, deburring, and surface finishing on metal and other hard materials. This cylinder-profile abrasive point features a B91 shape code, 60 grit medium grade, and mounts on a 0.125 inch diameter shank that is 1.5 inches long. The burnt orange aluminum oxide wheel head measures 0.625 inches thick and runs at a maximum of 34,500 RPM. It is intended for use with die grinders and rotary tools and is a standard consumable for machinists, toolroom technicians, fabricators, and maintenance trades performing internal grinding, slot finishing, and weld cleanup.

This mounted point fits common small die grinder and rotary tool applications where a cylinder-profile abrasive is required. The 0.125 inch shank diameter is a standard size compatible with most collet-style die grinder chucks. The 60 grit medium grade makes it suitable for general-purpose stock removal and surface blending on ferrous metals, castings, and weld beads. The aluminum oxide abrasive material is well suited for carbon steel, alloy steel, and similar hard metals encountered in industrial maintenance and fabrication environments.

Compatibility

Designed for use with collet-style die grinders and rotary tools accepting a 0.125 inch shank diameter. Verify that the tool RPM rating meets or exceeds the 34,500 RPM maximum speed before mounting.

Installation Notes

Mounting and replacement of abrasive points should be performed by qualified personnel familiar with abrasive tool safety. Always confirm the die grinder or rotary tool is disconnected from power before changing abrasive points. Ensure the collet is properly tightened to the manufacturer specification and inspect the mounted point for cracks or damage before each use. Do not exceed the 34,500 RPM maximum rated speed marked on the point or its packaging.
