Norton 61463624422 Mounted Point B52 90 Grit Fine

Product Description

The NORTON 61463624422 is a B52-shape vitrified aluminum oxide mounted point designed for precision grinding, deburring, and surface finishing on hard metals. The pointed B52 profile allows access to contoured surfaces, tight radii, and internal features where flat or wheel-style abrasives cannot reach. At 90 grit with a fine grade and hard bond density, this mounted point removes material efficiently while producing a consistent, controlled finish. It is rated to a maximum of 64,810 RPM and mounts via a 1/8 inch diameter shank, making it compatible with standard die grinders and rotary tools used in fabrication, tool-and-die, and maintenance grinding applications.

This mounted point is suited for use in metalworking environments including job shops, tool rooms, and production lines where operators need a reliable abrasive for internal grinding, weld cleanup, and detailed surface work. The brown aluminum oxide grain is a general-purpose abrasive well matched to ferrous metals such as carbon steel, alloy steel, and hardened tool steel. Typical users include machinists, maintenance technicians, and fabricators working with die grinders or flexible-shaft machines.

Key Features

• B52 pointed shape for access to contoured surfaces, slots, and internal profiles
• 90 grit, fine grade aluminum oxide abrasive for controlled stock removal and surface refinement
• Vitrified bond with hard density rating for consistent performance and shape retention
• 1/8 inch shank diameter fits standard die grinder collets and rotary tool chucks
• Maximum speed rating of 64,810 RPM for use with high-speed rotary tools
• Brown aluminum oxide grain suited for general-purpose grinding on ferrous metals

Compatibility

Designed for use with die grinders, flexible-shaft machines, and rotary tools accepting a 1/8 inch shank collet. Suited for general-purpose grinding on ferrous metals in tool-and-die, fabrication, and maintenance applications.

Installation Notes

Mounted points must be installed in a collet rated for the shank diameter and tightened securely before operation. Always verify the tool spindle speed does not exceed the 64,810 RPM maximum rating marked for this abrasive. Wear appropriate eye protection and guarding per ANSI B7.1 and shop safety requirements. Inspect the mounted point for cracks or damage before each use and discard any abrasive that shows signs of deterioration.
