Norton 61463624398 Mounted Point A31 Medium Aluminum Oxide

Product Description

The NORTON 61463624398 is a vitrified aluminum oxide mounted point designed for precision grinding, deburring, and surface blending on metal and ferrous materials. It features an A31 inverted cone cupped end shape, a medium grade abrasive, and a vitrified bond that holds the aluminum oxide grain firmly during high-speed rotary tool operation. The 1/4 inch shank fits standard die grinders and rotary tools, making this an everyday tool for machinists, fabricators, and maintenance technicians who need controlled material removal in confined or contoured areas.

This mounted point is suited for use in fabrication shops, maintenance facilities, and production environments where die grinders or flexible shaft tools are used for weld cleanup, port work, mold finishing, or internal bore blending. The A31 point shape with its inverted cone cupped end geometry allows access to recessed surfaces and angled workpiece faces. At 1 inch thick and 0.11 pounds, it is lightweight enough for extended use without excessive tool fatigue.

Key Features

• A31 inverted cone cupped end shape for access to recessed and contoured surfaces
• Aluminum oxide abrasive material for effective grinding on ferrous metals and hardened steels
• Vitrified bond provides consistent grain exposure and cool cutting action
• Medium grade abrasive balances material removal rate with surface finish quality
• 1/4 inch shank diameter fits standard die grinders and rotary tool chucks

Compatibility

Designed as an OEM-style replacement or direct-fit mounted point for die grinders and rotary tools accepting a 1/4 inch shank collet.

Installation Notes

Mounted points should be installed and operated by experienced machinists or trained trades personnel following applicable ANSI B7 safety standards for abrasive products. Inspect the point for cracks or damage before mounting, and ensure the tool RPM rating meets or exceeds the mounted point maximum speed. Always dress or true the point if necessary before use, and wear appropriate eye and face protection during operation.
