Norton 61463624438 B82 Mounted Point Medium Aluminum Oxide

Product Description

The NORTON 61463624438 is an aluminum oxide mounted point in the B82 inverted cone cupped end shape, designed for precision grinding, deburring, and surface blending in hard-to-reach areas. The abrasive head measures 0.25 inches thick and mounts on a 0.125 inch diameter shank with a 1.5 inch shank length, making it compatible with standard die grinders and rotary tools. Aluminum oxide is a general-purpose abrasive well suited to ferrous metals, carbon steel, and alloy steel. The medium grade balances stock removal rate with surface finish quality, making this point practical for both material removal and light finishing passes.

Mounted points like the 61463624438 are used in metal fabrication shops, maintenance and repair operations, and production grinding environments. Typical applications include weld blending, port matching, cavity grinding, and deburring of cast or machined metal components. The compact B82 inverted cone cupped end geometry allows the abrasive surface to contact recessed profiles, internal radii, and contoured surfaces that flat or cylindrical points cannot reach. This type of tooling is installed and operated by machinists, tool and die makers, welding professionals, and maintenance technicians.

Key Features

• B82 inverted cone cupped end shape reaches recessed surfaces and internal contours
• Aluminum oxide abrasive material suited for ferrous metals and general-purpose grinding
• Medium grade provides a balance of stock removal and surface finish
• 0.125 inch shank diameter fits standard die grinder collets and rotary tool chucks
• 1.5 inch shank length provides reach into cavities and deep workpiece features
• Single-piece packaging allows individual replacement without overstocking

Compatibility

Designed as a standard replacement or maintenance-supply mounted point for use with die grinders and rotary tools accepting a 0.125 inch shank diameter collet.

Installation Notes

Mounted points are installed and operated by trained machinists or metalworking technicians. Before mounting, verify that the grinder spindle speed does not exceed the maximum RPM rated for the abrasive point. Secure the shank fully within the collet and tighten per the tool manufacturer's torque guidance before operating. Always wear appropriate eye protection and ensure workpiece is secured prior to grinding.
