Norton 69014191720 Cbn Grinding Wheel 3-3/4 in Type 11V9 120 Grit

Product Description

The NORTON 69014191720 is a Type 11V9 cubic boron nitride (CBN) grinding wheel designed for precision tool grinding and sharpening applications. Built with a resinoid bond and a 100 concentration of CBN abrasive, this wheel delivers consistent stock removal and edge definition on hardened steels and ferrous tooling. The 120-grit fine grade produces a smooth finish suitable for finishing passes on cutting tools, carbide-tipped tooling, and HSS implements. At 3-3/4 inches in diameter with a 1-1/4-inch bore, it mounts to standard bench grinders and tool-and-cutter grinder spindles used in machine shops and trade maintenance environments. The wheel supports both wet and dry operation and weighs 0.64 pounds.

This wheel is suited for tool rooms, maintenance shops, and grinding stations where technicians need to sharpen or recondition cutting tools, drills, end mills, and similar implements. The Type 11V9 flaring cup profile with a 70-degree face angle and 3/8-inch face width concentrates the abrasive contact zone, improving precision on relief and clearance angles. The 1/16-inch superabrasive depth provides extended usable wheel life before the CBN layer is consumed. Both wet coolant setups and dry grinding configurations are supported, giving flexibility across different shop setups.

Compatibility

Designed as an OEM-style replacement or direct-fit grinding wheel for bench grinders and tool-and-cutter grinders accepting a 1-1/4-inch arbor bore and Type 11V9 cup wheel geometry. Specification code CB120-WB99-1/16 can be used for cross-reference with other Norton catalog listings.

Installation Notes

CBN grinding wheels should be mounted and dressed by a qualified machine operator or toolroom technician following the grinder manufacturer's wheel-speed and flange-clamping requirements. Always verify that the grinder's rated RPM does not exceed the wheel's maximum operating speed before mounting. Power down and lock out the grinder before changing wheels. Inspect the wheel for cracks or chips before each use and never operate a damaged wheel.
