Norton 69014191839 Cbn Grinding Wheel 120 Grit Type 11V9

Product Description

The NORTON 69014191839 is a Type 11V9 cubic boron nitride (CBN) grinding wheel built for precision tool grinding applications. It carries a 120-grit, fine-grade abrasive with a resinoid bond and a CBN superabrasive concentration of 75. The wheel measures 3-3/4 inches in diameter, 1-1/2 inches overall thickness, with a 1/4-inch superabrasive depth and a 3/8-inch face width. The face is angled at 70 degrees, making it well-suited for form-grinding and sharpening operations on hard materials. Licensed under the AZTEC III 120T-1/8 specification, this wheel supports both wet and dry operation, giving grinding professionals flexibility depending on their setup and coolant availability.

This wheel is intended for use on bench grinders and tool-and-cutter grinders in machine shops, tool rooms, and industrial maintenance environments. It is typically installed by machinists or tool grinding technicians sharpening carbide and high-speed-steel tooling. The 1-1/4-inch bore and 2-21/32-inch hub diameter are sized to fit standard spindle configurations common in precision tool grinding machines. Both wet and dry operation are supported, making it adaptable to shops with or without coolant systems.

Compatibility

Designed as an OEM-style replacement or direct-fit grinding wheel for Type 11V9 bench and tool-and-cutter grinder spindles with a 1-1/4-inch bore.

Installation Notes

Installation should be performed by a qualified machinist or grinding equipment technician. Always power down and lock out the grinder before mounting or removing a wheel. Inspect the wheel for cracks or chips before installation and never exceed the maximum RPM rating marked on the wheel or machine. Flanges and blotters should be clean, flat, and sized to the wheel bore per ANSI B7.1 safety standards.
