Norton 61463624405 Mounted Point 60 Grit Aluminum Oxide

Product Description

The NORTON 61463624405 is an aluminum oxide mounted point in the A37 wheel tapered edge shape, designed for precision grinding, deburring, and surface finishing on metal workpieces. It carries a 60-grit medium grade abrasive bonded with a vitrified bond, delivering consistent stock removal and a controlled finish. The point mounts on a 0.25-inch diameter, 1.5-inch long shank and is rated to a maximum of 30,560 RPM. At 0.06 pounds, it is lightweight and well-suited for use in die grinders and rotary tools across production and maintenance grinding applications. Installers and machinists select this type of point for internal bore work, cavity finishing, and hard-to-reach surface preparation.

This mounted point is used in metalworking, fabrication shops, and maintenance environments where a small, controllable abrasive is needed for internal grinding, port matching, weld cleanup, and slot or hole finishing. Its medium density and medium hardness rating make it appropriate for general-purpose steel and ferrous metal grinding where moderate material removal is required without aggressive surface damage.

Key Features

• A37 wheel tapered edge point shape for internal and contoured surface grinding
• 60-grit medium grade aluminum oxide abrasive for balanced stock removal and finish
• Vitrified bond for consistent abrasive exposure and dimensional stability during use
• 0.25-inch shank diameter fits standard die grinder and rotary tool collets
• Maximum rated speed of 30,560 RPM for compatibility with high-speed rotary tools
• Medium density and hardness for general-purpose ferrous metal grinding

Compatibility

Designed for use with die grinders and rotary tools accepting a 0.25-inch collet. Verify that the tool RPM rating meets or exceeds 30,560 RPM before use.

Installation Notes

Installation should be performed by a qualified machinist or tool operator familiar with mounted abrasive safety practices. Always confirm the spindle speed of the tool does not exceed the maximum RPM marked on the point or its packaging before mounting. Inspect the point for chips or cracks before each use and discard any damaged abrasive. Follow ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels.
