Tru-maxx TM-GPB136O Mounted Point 60 Grit 1/8 Inch Shank

Product Description

The TRU-MAXX TM-GPB136O is an aluminum oxide mounted point designed for precision grinding, deburring, and surface finishing on metal and hard materials. The cylinder-shaped point (B136 shape code) measures 5/16 inches thick and runs on a 1/8 inch diameter shank that is 1.5 inches long. Rated at a maximum of 77,250 RPM, this mounted point is built for use in die grinders and rotary tools. The 60 grit, medium grade abrasive removes material efficiently while leaving a consistent finish. The aluminum oxide construction handles ferrous metals, hardened steel, and cast iron without loading quickly.

This mounted point suits tool and die work, weld cleanup, port matching, mold finishing, and general metalworking applications. It is typically used by machinists, maintenance technicians, and fabricators working with handheld or bench-mounted rotary equipment. The 1/8 inch shank fits the most common collet size on standard die grinders, making it a straightforward drop-in for production or repair environments. The burnt orange color indicates the aluminum oxide abrasive type, which is a common shop-floor identifier for this material class.

Installation Notes

This mounted point is installed and removed by a licensed or trained machinist or maintenance technician using the appropriate collet wrench for the host tool. Ensure the die grinder is unplugged or the air supply is disconnected before changing mounted points. Never exceed the marked maximum RPM of 77,250 RPM. Inspect the point for cracks or chips before each use and discard any damaged abrasive immediately.
