Norton 61463624475 Mounted Point B131 60 Grit

Product Description

The NORTON 61463624475 is a vitrified aluminum oxide mounted point designed for precision grinding, deburring, and surface finishing in tight spaces and hard-to-reach areas. Shaped as a cylinder (B131 point shape code), this mounted point runs at up to 62420 RPM on a 1/8-inch shank, making it suitable for use with die grinders and rotary tools. The 60-grit, medium-grade abrasive delivers an aggressive cut on ferrous metals, castings, and welds without sacrificing control. Vitrified bond construction provides consistent grain exposure and cooler cutting action compared to resin-bond alternatives, extending the useful life of the point during sustained stock removal work.

This mounted point is used in metal fabrication shops, machine shops, and maintenance environments where internal bore grinding, port matching, weld blending, and burr removal are routine tasks. The 1/8-inch shank diameter fits standard die grinder collets and flexible shaft tools. Its compact cylinder profile is well-suited for working inside bores, slots, and contoured recesses where larger abrasive tooling cannot reach. The medium grade and 60 grit combination make it a practical choice for general-purpose stock removal on steel, cast iron, and similar hard materials.

Compatibility

Designed for use with die grinders, rotary tools, and flexible shaft machines equipped with a 1/8-inch collet. Suitable for grinding ferrous metals, cast iron, steel, and similar hard materials.

Installation Notes

Mounted points must be installed in a collet rated for the 1/8-inch shank diameter and tightened securely before operation. Always verify that the tool spindle speed does not exceed the 62420 RPM maximum marked on the product. Wear appropriate eye protection and follow ANSI B7.1 safety standards for abrasive product use. Inspect the mounted point for chips or cracks before each use and discard any damaged point immediately.
