Tru-maxx 66253291619 Mounted Point 60 Grit 1/8 in Shank

Product Description

The TRU-MAXX 66253291619 is an aluminum oxide mounted point designed for precision grinding, deburring, and surface finishing on hard metals and ferrous materials. Shaped as an inverted cone with a radius end (shape code B115), this mounted point delivers controlled stock removal in tight spaces and contoured surfaces. It runs at a medium grade with 60 grit abrasive, making it well suited for intermediate material removal and blending operations. The 1/8 inch shank diameter fits standard die grinder and rotary tool collets, and the 1/8 inch head thickness allows access to narrow grooves and recesses. Rated to 91,770 RPM maximum.

This mounted point is used in metalworking, maintenance, and fabrication applications where a handheld die grinder or rotary tool is required. Common tasks include deburring cast iron or steel parts, grinding weld seams in confined areas, and finishing internal bores or slots. The B115 inverted cone radius end geometry is particularly useful for working along angled surfaces and inside contoured workpieces. It is installed and used by machinists, maintenance mechanics, tool and die workers, and general metal fabricators in both shop and field settings.

Key Features

• Inverted cone radius end geometry (shape code B115) for access to contoured and recessed surfaces
• 60 grit, medium grade aluminum oxide abrasive for intermediate stock removal and blending
• 1/8 inch shank diameter fits standard die grinder and rotary tool collets
• Maximum operating speed of 91,770 RPM
• Pink aluminum oxide construction for grinding ferrous metals and hard alloys
• 1/8 inch head thickness for work in narrow grooves and tight clearances

Compatibility

Designed for use with die grinders and rotary tools accepting a 1/8 inch shank collet. Suitable for grinding, deburring, and finishing ferrous metals including steel and cast iron.

Installation Notes

Mounted points must be installed in a collet that matches the shank diameter exactly — a loose-fitting collet creates vibration and is a safety hazard. Before mounting, inspect the abrasive head for cracks or chips and discard any damaged point. Always operate below the rated maximum RPM and wear appropriate eye protection and gloves. Allow the mounted point to run at operating speed for a brief break-in period before applying it to the workpiece.
