Tru-maxx 66253291580 Mounted Point 60 Grit Aluminum Oxide

Product Description

The TRU-MAXX 66253291580 is an aluminum oxide mounted point designed for precision grinding, deburring, and surface finishing in metalworking and fabrication applications. Formed in an inverted cone flat end geometry (shape code B102), this mounted point runs at up to 45,370 RPM and delivers consistent medium-grade material removal at 60 grit. The 1/8 inch shank diameter fits standard die grinders and rotary tools, while the 1/2 inch head thickness provides adequate contact area for internal bore work, cavity finishing, and weld cleanup. Aluminum oxide abrasive is well suited to ferrous metals, hardened steel, and cast iron. Each unit ships individually and is sold in minimum quantities of 5.

This mounted point is used in machine shops, maintenance facilities, and fabrication environments where controlled grinding in confined areas is required. The B102 inverted cone flat end shape is commonly applied to internal radius blending, die work, port grinding, and chamfer cleanup on steel and iron components. The 1/8 inch shank makes it compatible with the wide range of die grinders and flexible shaft machines that accept 1/8 inch collets. Installation and use are appropriate for machinists, tool and die makers, maintenance mechanics, and skilled fabricators.

Key Features

• Inverted cone flat end geometry (B102) for internal bore and cavity grinding
• 60 grit medium grade aluminum oxide abrasive for consistent material removal on ferrous metals
• 1/8 inch shank diameter fits standard die grinders and rotary tool collets
• Maximum operating speed of 45,370 RPM
• 1/2 inch head thickness with 1-1/2 inch shank length for reach into recessed areas
• Blue color coding for quick grit and grade identification at the bench

Compatibility

Designed for use with die grinders, flexible shaft machines, and rotary tools fitted with a 1/8 inch collet. Suitable for grinding, deburring, and finishing ferrous metals including steel, hardened steel, and cast iron.

Installation Notes

Mounted points must be installed in a collet that matches the shank diameter exactly — a 1/8 inch shank requires a 1/8 inch collet with no adapters that could introduce runout. Inspect the wheel for chips or cracks before mounting and never exceed the rated maximum RPM of 45,370. Ensure the workpiece is secured and wear appropriate eye and face protection per ANSI B11 and OSHA grinding safety requirements. Do not use on non-ferrous metals or materials not compatible with aluminum oxide abrasive without verifying suitability.
