Norton 61463624443 Mounted Point B91 60 Grit Aluminum Oxide

Product Description

The NORTON 61463624443 is a vitrified aluminum oxide mounted point designed for precision grinding, deburring, and surface finishing on metal and hard materials. This flat cone profile (shape code B91) measures 5/8 inches thick and mounts on a 1/8 inch diameter shank with a 1-1/2 inch shank length. Rated to 61,110 RPM, it delivers consistent material removal at a 60 grit, medium grade cut. It is typically used with die grinders and rotary tools by machinists, tool and die makers, and maintenance technicians working on internal bores, contoured surfaces, and hard-to-reach areas.

This mounted point is suited for bench and portable grinding applications in manufacturing, fabrication, and maintenance environments. The flat cone shape makes it effective for work on concave surfaces, chamfers, and angled profiles. The vitrified bond provides a rigid, free-cutting action that holds grit securely under load, making it a practical choice for production grinding or detail finishing work on steel, iron, and similar hard metals. It ships in a minimum order quantity of 5 units.

Installation Notes

Mounted points must be installed and used by personnel familiar with abrasive tool safety practices per ANSI B7.1 guidelines. Verify the tool spindle speed does not exceed the 61,110 RPM maximum rating marked on the product before mounting. Inspect the point for cracks or chips before each use and discard any damaged abrasive. Secure the shank fully into the collet to the recommended depth and ensure the collet nut is tightened before operating.
