Norton 61463624390 Mounted Point A14 60 Grit Medium

Product Description

The NORTON 61463624390 is a vitrified aluminum oxide mounted point in cylinder shape code A14, designed for precision grinding, deburring, and surface finishing on metal workpieces. It runs at a maximum of 43,440 RPM and carries a medium, 60-grit abrasive structure bonded with a vitrified bond for consistent material removal and controlled cutting action. The 1/4-inch shank mounts directly into rotary die grinders and similar spindle tools. This part is sold individually and is intended for use by machinists, tool-and-die workers, and maintenance technicians who require a reliable, consistent abrasive point for internal or contoured grinding tasks.

This mounted point is suited for grinding operations on ferrous metals, cast iron, and general-purpose steels in both shop and field maintenance environments. The A14 cylinder profile makes it appropriate for working inside bores, slots, and recessed surfaces where flat or contoured stock removal is needed. The medium grade and 60-grit combination provides a balance between aggressive material removal and a reasonably smooth finished surface. It fits standard 1/4-inch collet die grinders commonly used in fabrication shops, maintenance facilities, and production grinding applications.

Key Features

• A14 cylinder shape for flat-faced and internal grinding applications
• 60-grit medium grade aluminum oxide abrasive for balanced stock removal and surface finish
• Vitrified bond provides consistent cut rate and open structure during grinding
• Rated to 43,440 RPM for use with standard die grinders
• 1/4-inch shank diameter fits common collet sizes
• 1-1/2-inch shank length provides clearance for deep or recessed workpieces

Compatibility

Designed for use with rotary die grinders and spindle-mounted grinding equipment accepting a 1/4-inch shank. Verify that the tool spindle speed does not exceed the 43,440 RPM rating of this mounted point before use.

Installation Notes

Installation is performed by machinists or maintenance technicians using a standard die grinder with a compatible 1/4-inch collet. Ensure the tool is fully powered off and depressurized before inserting or removing the mounted point. Never exceed the maximum RPM stamped or listed for the abrasive point, as overspeeding is a recognized safety hazard per ANSI B7.1 standards. Inspect the point for cracks or damage before each use and discard any point that shows signs of chipping or structural compromise.
