Norton 61463624472 Mounted Point B123 60 Grit

Product Description

The NORTON 61463624472 is a vitrified aluminum oxide mounted point in ball shape profile B123, designed for precision grinding, deburring, and surface blending in confined areas. Rated at 60 grit with a medium grade density, it delivers consistent stock removal on ferrous and non-ferrous metals. The shank diameter measures 1/8 inches, the shank length is 1.5 inches, and the head thickness is 3/16 inches. Weighing just 0.0067 pounds, this mounted point is built for rotary tools, die grinders, and high-speed spindles where access is tight and control is critical. It is installed and used by machinists, tool-and-die technicians, maintenance mechanics, and metalworking professionals.

This mounted point is suited for internal grinding, port work, weld blending, and deburring operations on metal workpieces in both production and maintenance environments. The ball profile makes it well matched for contoured surfaces, radiused bores, and concave geometry where flat or tapered profiles cannot reach. It is commonly used in job shops, fabrication facilities, and MRO settings where small-diameter rotary abrasives are standard tooling. The vitrified bond provides a cool, consistent cut and good wheel breakdown characteristics under moderate pressure.

Compatibility

Designed as an OEM-style mounted point for use in die grinders, rotary tools, and spindle fixtures accepting a 1/8 inch shank. Confirm tool RPM rating meets or exceeds 84,720 RPM before use.

Installation Notes

A licensed machinist or qualified metalworking technician should mount and operate this abrasive point. Before installing, confirm the tool spindle RPM does not exceed the 84,720 RPM maximum rating marked on this product. Secure the shank fully into the collet and inspect for runout before beginning work. Always wear appropriate PPE including eye protection and follow applicable ANSI B7.1 grinding safety standards during use.
