Tru-maxx 66253291686 Mounted Point A32 60 Grit Aluminum Oxide

Product Description

The TRU-MAXX 66253291686 is an aluminum oxide mounted point in an A32 inverted cone cupped end shape, designed for precision grinding, deburring, and surface finishing on metal and ferrous materials. The vitrified bond holds the 60-grit abrasive grain firmly at operating speeds up to 38,200 RPM, delivering consistent stock removal with medium-grade cutting action. The 0.25-inch shank diameter fits standard die grinder and rotary tool collets, making it a go-to abrasive for machinists, tool-and-die technicians, and maintenance mechanics working on tight internal geometries, bores, and contoured surfaces. At 0.02 pounds, it is lightweight and easy to control in extended use.

This mounted point is suited for bench grinder work, die grinder applications, and handheld rotary tool operations in machine shops, maintenance facilities, and production grinding environments. The A32 point shape is particularly useful for grinding inside cavities, chamfering bores, and blending weld seams in areas where flat or cup wheels cannot reach. It is sold individually and is well-matched for both light deburring passes and more aggressive material removal at controlled feed rates.

Key Features

• A32 inverted cone cupped end geometry for internal and contoured surface grinding
• 60-grit medium-grade aluminum oxide abrasive for balanced cut rate and finish
• Vitrified bond construction for consistent grain exposure throughout wheel life
• Rated to 38,200 RPM maximum operating speed
• 0.25-inch shank diameter fits standard die grinder and rotary tool collets
• 1.5-inch shank length provides reach into recessed areas

Compatibility

Designed for use with die grinders and rotary tools accepting a 0.25-inch collet. Suitable for grinding aluminum oxide-compatible applications on ferrous metals and hardened steels.

Installation Notes

Mounted points must be installed and operated by personnel familiar with abrasive wheel safety per ANSI B7.1 guidelines. Inspect the shank and abrasive head for cracks or damage before each use and never operate above the rated maximum RPM of 38,200. Ensure the collet is tightened securely and the workpiece is properly fixtured before engaging the abrasive. Always wear appropriate eye protection and guarding as required by applicable shop safety standards.
