Tru-maxx TM-GPB44O B44 Tree Mounted Point 60 Grit

Product Description

The TRU-MAXX TM-GPB44O is an aluminum oxide mounted point in the B44 tree shape, designed for precision grinding and deburring on ferrous metals, castings, and hard materials. At 60 grit with a medium grade, it removes material efficiently while leaving a surface finish suitable for further processing. The point measures 0.375 inches in head thickness with a 0.125-inch shank diameter and 1.5-inch shank length, fitting standard rotary die grinders and flex-shaft tools. Rated to 68,400 RPM, it is suited for high-speed toolroom work, weld blending, and port work performed by machinists, tool-and-die makers, and maintenance technicians.

This mounted point is used in industrial maintenance, fabrication shops, and toolroom applications where internal or contoured surfaces require controlled stock removal. The tree profile of the B44 shape allows access to recessed areas, curved bores, and irregular cavities that flat or cylindrical points cannot reach. It is a single-piece consumable sold individually, with a minimum order quantity of 25 units, making it appropriate for shop stocking. Typical applications include deburring cast iron and steel components, blending weld seams, and refining mold surfaces.

Key Features

Compatibility

Designed for use with rotary die grinders and flex-shaft machines accepting a 0.125-inch collet. Verify tool RPM rating meets or exceeds the 68,400 RPM maximum before mounting.

Installation Notes

Mounting and use should be performed by qualified machinists or maintenance technicians familiar with abrasive tooling safety. Always confirm the spindle speed of the die grinder does not exceed the 68,400 RPM rating of this point before operation. Inspect the mounted point for cracks or chips before each use and never use a damaged abrasive. Wear appropriate eye protection and follow ANSI B7.1 safety requirements for abrasive products.
