Tru-maxx 66253291535 Mounted Point A13 60 Grit 1/4in Shank

Product Description

The TRU-MAXX 66253291535 is an A13 cylinder-profile mounted point designed for precision internal grinding, deburring, and surface finishing in metal fabrication and toolroom applications. The wheel is made from aluminum oxide abrasive bonded with a vitrified bond, producing a consistent cut on ferrous metals, cast iron, and general-purpose steels. At 60 grit with a medium grade, it removes material efficiently while leaving a workable surface finish. The 1/4-inch shank mounts directly into die grinders, rotary tools, and spindle-driven machines rated for the 31,850 RPM maximum speed. Shank length is 1.5 inches and head thickness is 1.125 inches. Weight is 0.02 pounds.

This mounted point is suited for internal bore work, slot grinding, and contour finishing on production lines and maintenance benches alike. Machinists, tool-and-die makers, and industrial maintenance technicians reach for A13 cylinder points when working inside housings, ports, and cavities where flat or flap wheels cannot reach. The vitrified bond holds grit firmly under steady spindle loads, making it appropriate for both light touch-up passes and moderate stock removal on hard ferrous materials.

Key Features

• A13 cylinder point shape for internal bore and cavity grinding
• 60 grit aluminum oxide abrasive for efficient stock removal on ferrous metals
• Vitrified bond for consistent grit exposure and cool cutting action
• 1/4-inch shank diameter fits standard die grinder and rotary tool collets
• Maximum rated speed of 31,850 RPM
• Medium grade delivers a balance of cut rate and surface finish quality

Compatibility

Designed as an OEM-style replacement or direct-fit mounted point for die grinders, rotary tools, and precision grinding spindles accepting a 1/4-inch shank collet and rated to operate at or above 31,850 RPM.

Installation Notes

Installation and use should be performed by machinists or maintenance technicians familiar with abrasive wheel safety. Always inspect the wheel for chips or cracks before mounting and confirm the tool spindle speed does not exceed the 31,850 RPM maximum rating marked on this point. Tighten the collet securely and allow the wheel to run free for a brief test spin before applying workpiece contact. Eye protection and appropriate guarding are required per ANSI B7.1 abrasive wheel safety standards.
