Norton 61463624481 Mounted Point B133 60 Grit Medium

Product Description

The NORTON 61463624481 is a vitrified aluminum oxide mounted point in cylinder shape B133, designed for precision grinding and surface finishing on ferrous metals, castings, and hard materials. With a 60-grit medium grade, it removes material efficiently while leaving a consistent finish suitable for deburring, port work, die finishing, and tight-radius grinding. The 3/8-inch head thickness and 1/8-inch shank diameter make it compatible with standard die grinders and rotary tools. It is rated to 68,740 RPM, giving technicians confidence in high-speed applications. The vitrified bond provides rigidity and free-cutting action, making this point a reliable choice for metalworking shops, tool-and-die operations, and maintenance technicians.

This mounted point is suited for use in industrial maintenance, fabrication, and tool-and-die applications where controlled material removal in confined areas is required. The cylinder profile provides flat contact on flat or slightly contoured surfaces, making it practical for cleaning weld seams, blending surfaces, and enlarging bores or ports. It is intended for use with pneumatic or electric die grinders accepting a 1/8-inch shank. The medium grit and medium hardness balance cut rate and wheel life for general-purpose ferrous grinding tasks.

Key Features

• Cylinder shape code B133 for flat-surface and bore grinding applications
• 60-grit medium grade balances material removal rate with surface finish quality
• Aluminum oxide abrasive is well-suited for ferrous metals and hard materials
• Vitrified bond provides rigidity and consistent free-cutting performance
• Rated to 68,740 RPM for use with standard high-speed die grinders
• 1/8-inch shank diameter fits widely available die grinder collets

Compatibility

Designed for use with pneumatic or electric die grinders and rotary tools fitted with a 1/8-inch collet. Suitable as a standard replacement or stock mounted point for ferrous metal grinding operations requiring a B133 cylinder profile.

Installation Notes

Mounted points must be installed and operated by qualified personnel familiar with abrasive tooling safety. Before mounting, inspect the point for cracks or damage and verify the tool spindle speed does not exceed the 68,740 RPM rating marked on this product. Secure the 1/8-inch shank fully into the collet and tighten to the tool manufacturer specification before applying the point to the workpiece. Always wear appropriate eye protection and follow ANSI B7.1 safety requirements for abrasive wheel use.
