Tru-maxx 66253291684 Mounted Point 60 Grit 1/4 in Shank

Product Description

The TRU-MAXX 66253291684 is an aluminum oxide mounted point grinding wheel in an inverted cone cupped end (A31) shape. It is designed for precision grinding, deburring, and surface finishing on ferrous metals and hard materials. The wheel uses a vitrified bond, which holds abrasive grains firmly and allows for consistent stock removal at controlled depths. At 60 grit with a medium grade, it removes material efficiently while leaving a moderately smooth surface. The 1/4-inch shank fits standard die grinder collets. This mounted point is installed by machinists, tool and die makers, maintenance technicians, and metalworking tradespeople who need controlled grinding in confined areas.

This mounted point is suited for internal grinding, port work, weld cleanup, and deburring operations on steel, cast iron, and similar hard metals. Its inverted cone cupped end geometry is well-matched for working on concave surfaces, inside bores, and recessed areas where flat or cylindrical wheels cannot reach. It mounts directly into a die grinder or rotary tool with a 1/4-inch collet and is appropriate for both bench-mounted and handheld power tool setups in shop or field maintenance environments.

Key Features

• Inverted cone cupped end (A31) shape for access to concave and recessed surfaces
• 60 grit medium grade aluminum oxide abrasive for efficient stock removal on hard metals
• Vitrified bond provides rigid grain retention and consistent grinding performance
• 1/4-inch shank diameter fits standard die grinder and rotary tool collets
• Rated to 27,780 RPM maximum operating speed
• Compact 1-3/8-inch head thickness suited for confined grinding applications

Compatibility

Designed for use with die grinders and rotary tools equipped with a 1/4-inch collet. Suitable for grinding and finishing operations on ferrous metals and hard materials in general metalworking and maintenance applications.

Installation Notes

Installation is performed by machinists or maintenance technicians using a die grinder with a matching 1/4-inch collet. Ensure the tool is unplugged or the air supply is disconnected before mounting or removing the wheel. Never exceed the rated maximum of 27,780 RPM. Inspect the mounted point for cracks or chips before each use and discard any wheel showing visible damage.
