Norton 61463624466 Mounted Point B121 60 Grit Medium

Product Description

The NORTON 61463624466 is a vitrified aluminum oxide mounted point designed for precision grinding, deburring, and surface finishing in metalworking and fabrication applications. It features a B121 ball point shape, 60 grit abrasive, and a medium density bond that delivers consistent stock removal on ferrous and non-ferrous metals. The 1/8-inch shank diameter fits standard die grinders and rotary tools, and the 1.5-inch shank length provides adequate reach into cavities, ports, and contoured workpieces. Rated to 62,420 RPM, this mounted point is suited for high-speed rotary tool use in production and maintenance environments. Installed by machinists, tool and die makers, and metal fabricators.

This mounted point is used for internal grinding, weld blending, mold finishing, and deburring operations where a ball-shaped abrasive profile is required. The B121 ball shape conforms well to concave surfaces, radius seats, and drilled port openings. It is appropriate for use in both shop and field maintenance settings where a die grinder or flexible-shaft machine is the primary tool. The medium grade and 60 grit combination suits general-purpose metal removal without excessive surface roughness.

Key Features

• B121 ball point shape for grinding concave surfaces, ports, and radius profiles
• 60 grit medium grade aluminum oxide abrasive for balanced stock removal and finish
• Vitrified bond provides rigidity and consistent cut rate throughout the wheel life
• 1/8-inch shank diameter compatible with standard die grinders and rotary tools
• Rated to 62,420 RPM for high-speed rotary tool operation
• 1.5-inch shank length allows reach into deep cavities and recessed areas

Compatibility

Designed for use with die grinders, flexible-shaft machines, and rotary tools accepting a 1/8-inch shank collet. Suitable for grinding aluminum oxide-compatible ferrous and non-ferrous metal workpieces.

Installation Notes

This mounted point is installed and operated by machinists, fabricators, and maintenance technicians using die grinders or rotary tools. Before mounting, confirm the tool collet is rated for 1/8-inch shanks and that the tool RPM does not exceed the 62,420 RPM rating marked on this abrasive. Secure the shank fully in the collet and tighten per the tool manufacturer specification before operation. Always wear appropriate eye protection and ensure the workpiece is secured before applying the abrasive.
