Norton 61463624470 Mounted Point B122 60 Grit

Product Description

The NORTON 61463624470 is an aluminum oxide mounted point designed for precision grinding, deburring, and surface finishing in confined areas. Formed in a B122 ball shape, it fits rotary tools, die grinders, and flexible shaft machines used in metalworking, tooling, and fabrication shops. The 60-grit medium-grade abrasive cuts aggressively enough for stock removal while leaving a workable surface finish. A vitrified bond holds the grain firmly throughout the wheel life, supporting consistent cut rates from start to finish. This mounted point is a standard choice for machinists, tool-and-die makers, and maintenance technicians working on internal radii, bores, and curved surfaces.

This mounted point suits applications in ferrous metal grinding including steel, cast iron, and hardened tool steel. The ball profile allows access to concave surfaces, weld seads, and tight internal geometries where flat or cone-shaped points cannot reach. It is used in production grinding, mold and die finishing, and general maintenance deburring in industrial, commercial, and job-shop environments. The 1/8-inch shank diameter is a widely used standard size that fits a broad range of die grinder and rotary tool collets.

Key Features

• B122 ball point shape for grinding curved and concave surfaces
• 60-grit aluminum oxide abrasive for medium-grade stock removal
• Vitrified bond construction for consistent cut and grain retention
• Maximum operating speed of 68,740 RPM
• 1/8-inch shank diameter fits standard die grinder and rotary tool collets
• Compact 3/8-inch head thickness for access to tight workspaces

Compatibility

Designed for use with die grinders, rotary tools, and flexible shaft machines accepting a 1/8-inch shank collet. Verify that the spindle speed of the host tool does not exceed the maximum rated RPM before mounting.

Installation Notes

Always power down and disconnect the host tool before mounting or changing a mounted point. Inspect the wheel for chips or cracks before each use and discard any damaged point. Secure the shank fully into the collet to the depth recommended by the tool manufacturer, and confirm the spindle speed does not exceed 68,740 RPM. Eye protection and appropriate PPE are required during grinding operations per ANSI B7.1 safety standards.
