Tru-maxx 66253291547 Mounted Point Ball A24 60 Grit

Product Description

The TRU-MAXX 66253291547 is an aluminum oxide mounted point in the A24 ball shape, designed for precision grinding, deburring, and surface blending in hard-to-reach areas. The vitrified bond holds 60-grit abrasive grains firmly, delivering consistent stock removal at a medium grade. This mounted point fits a 1/4-inch shank collet and is rated to a maximum of 56,000 RPM, making it suitable for use in die grinders and rotary tools. The pink aluminum oxide construction is well suited for general-purpose grinding on ferrous metals and hard materials. Machinists, tool-and-die technicians, and maintenance professionals install this type of abrasive point for internal grinding and contour work.

This mounted point is used in shop maintenance, toolroom grinding, and fabrication applications where a standard grinding wheel cannot access the work surface. The ball profile of the A24 shape makes it effective for grinding concave surfaces, radiused recesses, and bore interiors. It is suitable for use on hardened steel, cast iron, and similar ferrous workpieces. The 3/4-inch head thickness and 1-1/2-inch shank length provide adequate reach and material for controlled grinding passes without excessive deflection.

Installation Notes

Mounted points of this type are installed and changed by machinists, toolroom technicians, and maintenance professionals using a die grinder with a matching collet size. Always verify the tool spindle speed does not exceed the 56,000 RPM rating marked on this point before operation. Inspect the mounted point for cracks or chips before each use and discard any damaged abrasive. Power down and de-energize the tool completely before changing abrasive accessories.
