Norton 61463624468 Mounted Point B121 Medium Fine

Product Description

The NORTON 61463624468 is a ball-shaped mounted point designed for precision grinding, deburring, and surface blending in hard-to-reach areas. It features a B121 ball profile ground from medium fine aluminum oxide abrasive, giving it a balanced cut rate suited for light stock removal and finishing work on ferrous and non-ferrous metals. The 0.5 inch head thickness and 0.125 inch shank diameter make it compatible with standard die grinders and rotary tools. It is typically installed and used by machinists, tool-and-die workers, welders, and maintenance technicians working on internal bores, cavities, and contoured surfaces.

This mounted point is well suited for bench or portable die grinder work in manufacturing, fabrication, and maintenance environments. Its medium fine grade and aluminum oxide composition handle general-purpose grinding on steel, cast iron, and similar materials. The compact ball geometry allows access to recessed profiles, weld beads in tight joints, and irregular internal surfaces where flat or straight abrasives cannot reach. Sold individually, it is appropriate for both production grinding and occasional precision finishing tasks.

Compatibility

Designed as a standard OEM-style replacement or stock abrasive for die grinders and rotary tools accepting a 0.125 inch shank diameter mounted point.

Installation Notes

Mounted points are installed by machinists and fabricators using a die grinder or compatible rotary tool with the correct collet size. Before mounting, verify the tool RPM rating meets or exceeds the mounted point maximum speed rating. Inspect the abrasive head for cracks or chips before each use and do not use damaged points. Always use appropriate eye protection and guarding per applicable workplace safety standards.
