Norton 61463624397 Mounted Point A26 60 Grit 1/4 in Shank

Product Description

The NORTON 61463624397 is an aluminum oxide mounted point in ball shape (A26) designed for precision grinding, deburring, and surface finishing on metal and ferrous materials. It carries a 60-grit medium grade abrasive bonded with a vitrified bond for consistent stock removal and dimensional stability under load. The 1/4-inch shank fits standard die grinders and rotary tools used in fabrication, maintenance, and tool-and-die shops. Rated to 48,980 RPM, it delivers reliable performance at high spindle speeds. The brown aluminum oxide abrasive is well-suited for general-purpose work on steel and other hard metals where controlled material removal is required.

This mounted point is used in metalworking environments including fabrication shops, machine shops, and industrial maintenance operations. Typical applications include grinding welds, cleaning casting flash, deburring bores and ports, and blending surface irregularities in confined areas where flat wheels cannot reach. The ball shape makes it particularly effective for internal grinding of curved or contoured surfaces. It is installed in die grinders, flexible shaft machines, and similar rotary tools equipped with a 1/4-inch collet.

Key Features

• Ball shape (A26) for internal and contoured surface grinding
• 60-grit medium grade aluminum oxide abrasive for controlled stock removal
• Vitrified bond provides rigidity and consistent cutting action
• Rated to 48,980 RPM for use in high-speed die grinders
• 1/4-inch shank diameter fits standard collet sizes on most rotary tools
• 5/8-inch head thickness for adequate material in finish and deburring passes

Compatibility

Designed for use in die grinders, flexible shaft machines, and rotary tools with a 1/4-inch collet accepting standard mounted point shanks.

Installation Notes

Mounted points are installed and removed by a qualified operator using the tool manufacturer's collet tightening procedure. Always verify the tool spindle RPM does not exceed the 48,980 RPM rating marked on this point before mounting. Inspect the abrasive head for cracks or chips before each use and discard any damaged point. Wear appropriate eye protection and follow ANSI B7.1 safety standards for abrasive wheel use.
