Norton 61463624407 Mounted Point A39 60 Grit Aluminum Oxide

Product Description

The NORTON 61463624407 is a vitrified aluminum oxide mounted point designed for precision grinding, deburring, and surface finishing in tight or contoured areas. The A39 cylinder profile delivers consistent contact across flat internal surfaces, making it a go-to for tool and die work, mold finishing, and production grinding. Rated to 44,030 RPM, this mounted point runs at medium grade and 60 grit, providing an aggressive yet controlled cut on ferrous metals. The 1/4 inch shank fits standard die grinders and flexible shaft machines used across industrial and maintenance trades.

This mounted point is suited for grinding, blending, and deburring operations on steel, cast iron, and other ferrous materials. The cylinder shape and medium-hard vitrified bond make it appropriate for internal diameter grinding, port work, and finishing recesses where larger wheels cannot reach. It is commonly used in fabrication shops, tool rooms, and maintenance settings. The 3/4 inch head thickness and 1-1/2 inch shank length provide solid reach into cavities without sacrificing rigidity during operation.

Key Features

• A39 cylinder point shape for consistent flat-surface contact in bores and recesses
• 60 grit aluminum oxide abrasive for aggressive stock removal on ferrous metals
• Vitrified bond construction for cool cutting and shape retention
• Medium grade density suited for general-purpose grinding and deburring
• 44,030 RPM maximum speed rating for use with standard die grinders
• 1/4 inch shank diameter compatible with common die grinder collets

Compatibility

Designed for use with die grinders and flexible shaft machines fitted with a 1/4 inch collet. Suitable for grinding ferrous metals in applications where an A39 cylinder-profile mounted point is specified.

Installation Notes

Mounted points must be installed and operated by personnel familiar with abrasive grinding safety per ANSI B7.1 guidelines. Always inspect the point for cracks or chips before mounting and do not exceed the rated 44,030 RPM. Secure the shank fully in the collet and run the point at operating speed in a protected area for at least one minute before applying it to the workpiece. Wear appropriate eye and face protection during all grinding operations.
