Norton 69014191724 Cbn Grinding Wheel 3-3/4 in 150 Grit

Product Description

The NORTON 69014191724 is a Type 11V9 cubic boron nitride (CBN) grinding wheel designed for precision tool grinding applications. Built with a resinoid bond and a 150-grit very fine abrasive, it is engineered for sharpening and finishing operations where close tolerances and surface quality matter. The wheel measures 3-3/4 inches in diameter with an overall thickness of 1-1/2 inches and a 1-1/4-inch arbor hole. A 1/8-inch superabrasive depth and a 3/8-inch face width concentrate the CBN abrasive where the cutting action occurs. Rated for both wet and dry operation, this wheel suits machine shops, tool-and-cutter grinding setups, and maintenance environments where high-hardness tooling needs consistent edge preparation.

This wheel is intended for use on bench grinders, tool-and-cutter grinders, and CNC grinding machines that accept a Type 11V9 cup wheel configuration. A 70-degree face angle and a hub diameter of 2-21/32 inches make it well suited for grinding carbide, high-speed steel, and other hard tool materials. It is typically installed and operated by machinists, toolroom technicians, or experienced maintenance professionals working on cutting tool reconditioning.

Key Features

Compatibility

Designed for use on tool-and-cutter grinders and bench grinding machines that accept a Type 11V9 cup wheel with a 1-1/4-inch arbor hole and a 3-3/4-inch wheel diameter.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Disconnect and lock out power to the grinder before mounting or removing any wheel. Inspect the wheel for visible cracks or chips before each use and perform a ring test per standard abrasive wheel safety practice. Always verify that the machine speed rating meets or exceeds the wheel speed rating before operation, and use appropriate flanges and blotters as specified by ANSI B7.1 safety standards.
