Norton 69083154055 Mounted Point W179 36 Grit Ceramic

Product Description

The NORTON 69083154055 is a ceramic abrasive mounted point designed for precision grinding, deburring, and surface finishing in metalworking and fabrication applications. It features a W179 cylinder shape with a 36-grit, extra-coarse ceramic abrasive grain, making it well suited for aggressive stock removal on hard materials. The 1/4-inch shank diameter fits standard die grinders and rotary tools. With a very hard density rating and a maximum operating speed of 20,415 RPM, this mounted point delivers consistent cutting action under demanding conditions. It is installed and operated by machinists, tool-and-die workers, and fabricators working on metal surfaces, weld seams, and internal bores.

This mounted point is used in industrial and job-shop environments for grinding ferrous and non-ferrous metals, removing weld flash, cleaning up casting imperfections, and deburring drilled or machined holes. The ceramic abrasive grain self-sharpens during use, maintaining a consistent cut rate over the life of the point. The green color identifies the ceramic grain type. It is suitable for handheld die grinder work as well as stationary rotary tool setups where controlled grinding of tight or recessed areas is required.

Compatibility

Designed as a standard 1/4-inch shank mounted point compatible with die grinders, flexible shaft machines, and rotary tools accepting 1/4-inch collets or chucks.

Installation Notes

Mounted points must be installed in a tool rated at or above the maximum RPM marked on the point — never exceed 20,415 RPM with this abrasive. Secure the shank fully in the collet before operation and inspect the point for cracks or chips before each use. Wear appropriate eye protection and follow ANSI B7.1 safety requirements for abrasive product handling. Power down and de-energize the tool completely before changing mounted points.
