Norton 69014192299 Type 11V9 Cbn Grinding Wheel 120 Grit

Product Description

The NORTON 69014192299 is a Type 11V9 superabrasive grinding wheel engineered for precision material removal on hardened steels and ferrous alloys. The abrasive matrix uses Cubic Boron Nitride (CBN), a superabrasive second only to diamond in hardness, bonded with a resinoid bond for consistent stock removal and surface finish control. The wheel measures 5 inches in diameter and 1-3/4 inches overall thickness, with a 120 grit, fine-grade face suited for finishing and tight-tolerance grinding operations. It supports both wet and dry operation, making it adaptable to bench grinder and surface grinder setups commonly found in tool rooms and machine shops.

This wheel is intended for tool and cutter grinding, jig grinding, and precision form grinding applications where surface integrity and dimensional accuracy are critical. The Type 11V9 cup geometry with a 70-degree face angle is specifically designed for grinding tool faces, clearance angles, and flutes on cutting tools such as end mills, drills, and reamers. Licensed machinists, tool grinders, and shop technicians working with carbide-backed or hardened HSS tooling are the primary installers and operators of this wheel.

Key Features

• Type 11V9 cup wheel geometry with 70-degree face angle for precise tool face grinding
• 120 grit, fine grade provides a balance of stock removal and surface finish quality
• Resinoid bond offers controlled abrasive release and consistent cut across wet and dry operation
• Superabrasive depth of 1/16 inch and face width of 7/16 inch for focused, controlled contact
• 1-1/4 inch arbor hole fits standard bench and surface grinder spindles

Compatibility

Designed for use on bench grinders and tool and cutter grinders accepting a 1-1/4 inch arbor hole and accommodating a 5 inch diameter Type 11V9 cup wheel. Verify maximum RPM rating of the machine spindle against the wheel rating before mounting.

Installation Notes

Mounting and dressing of superabrasive wheels should be performed by a qualified machinist or tool grinder familiar with ANSI B11 grinding safety standards. Power down and lock out the grinder before removing or installing any wheel. Inspect the wheel for cracks or chips prior to mounting and conduct a ring test per standard practice. Never exceed the maximum operating speed marked on the wheel, and always use the appropriate flanges and blotters as specified by the wheel manufacturer.
