Tru-maxx GPB125B Aluminum Oxide Mounted Point Ball Shape

Product Description

The TRU-MAXX GPB125B is an aluminum oxide mounted point in a B125 ball shape, designed for precision grinding, deburring, and surface finishing on metal and other hard materials. The abrasive head measures 1/4 inch thick and mounts on a 1/8 inch diameter shank with a 1-1/2 inch shank length. Rated to a maximum of 61,650 RPM, this mounted point delivers aggressive stock removal with a medium-grade, hard-density wheel construction. It is color-coded blue for quick grade identification at the bench or toolbox. Machinists, tool and die makers, and maintenance technicians use this style of mounted point for internal grinding, port work, and tight-clearance finishing operations.

The GPB125B suits applications where a rotary tool, die grinder, or flexible shaft machine is used with a 1/8 inch collet. Typical uses include weld cleanup, cavity work in molds and dies, deburring cast iron or steel components, and detail grinding in areas inaccessible to conventional grinding wheels. The ball profile allows contact on curved and contoured surfaces. This point is sold individually and is suited to both production shop and maintenance-repair environments.

Installation Notes

Mounted points must be installed and operated by personnel familiar with abrasive wheel safety. Always confirm the tool spindle RPM rating meets or exceeds 61,650 RPM before mounting. Inspect the point for cracks or chips before each use and discard any damaged point immediately. Secure the shank fully in the collet per the tool manufacturer guidelines and run the point under guard or in a controlled direction away from bystanders during initial spin-up.
