Tru-maxx 66253291650 Mounted Point B123 60 Grit 1/8 in Shank

Product Description

The TRU-MAXX 66253291650 is an aluminum oxide mounted point in a B123 ball shape, designed for precision grinding, deburring, and surface finishing on ferrous and non-ferrous metals. The abrasive head measures 3/16 inches thick and is bonded to a 1/8 inch diameter shank that runs 1-1/2 inches in length. Rated at 84,720 RPM maximum, this medium-grade, 60-grit point delivers consistent stock removal on internal bores, contours, and hard-to-reach surfaces. The pink aluminum oxide bond is well-suited for general-purpose tool room and production grinding work.

This mounted point is used in die grinders, rotary tools, and flexible shaft machines across metalworking, tool and die, maintenance, and fabrication applications. The B123 ball profile is commonly selected for blending radii, cleaning up weld spatter, and finishing inside curved or irregular cavities. It suits both bench and handheld rotary tool setups and is a staple in machine shops and maintenance departments handling light-to-medium material removal on steel, cast iron, and similar metals.

Key Features

• B123 ball shape profile for grinding internal contours and curved surfaces
• 60 grit, medium grade aluminum oxide abrasive for general-purpose stock removal
• Maximum rated speed of 84,720 RPM for compatibility with standard die grinders and rotary tools
• 1/8 inch shank diameter fits standard collets on most die grinders and rotary tools
• 1-1/2 inch shank length provides reach into recessed areas and deep bores
• Pink aluminum oxide construction offers consistent cut and long service life on ferrous metals

Compatibility

Designed for use with die grinders and rotary tools accepting a 1/8 inch collet. Suitable for general-purpose grinding on ferrous and non-ferrous metals, tool steel, and cast iron.

Installation Notes

This mounted point is installed and serviced by machinists, tool and die makers, and maintenance technicians. Before mounting, confirm the tool spindle speed does not exceed the 84,720 RPM rating marked on the point. Secure the shank fully into the collet to the recommended depth and inspect the abrasive head for cracks or chips before each use. Never force the point into a workpiece or apply side-loading pressure beyond what the abrasive bond is designed to handle.
