Norton 69014192020 Cbn Grinding Wheel 120 Grit 6 in

Product Description

The NORTON 69014192020 is a Type 12V9 cubic boron nitride (CBN) superabrasive grinding wheel designed for precision tool grinding applications. It carries a 120 grit, fine grade and uses a resinoid bond to deliver consistent stock removal and surface finish on hardened ferrous materials, HSS tooling, and carbide-adjacent workpieces. The wheel measures 6 inches in diameter with a 1/2-inch overall thickness and a 1-1/4-inch arbor hole. CBN concentration is rated at 75, and the superabrasive layer depth is 1/8 inch. This wheel is built for both wet and dry operation, making it adaptable to a range of bench grinder and surface grinder setups used by tool and cutter grinders and machining professionals.

This wheel is suited for sharpening and reconditioning cutting tools, form grinding, and precision surface work on hardened steel components. The 30-degree face angle and 3/8-inch face width make it appropriate for tool flute grinding, relief angle work, and similar applications where edge geometry must be maintained accurately. It fits tool cutter grinder setups common in job shops, maintenance environments, and production grinding operations. The 3-13/32-inch hub diameter provides stable seating on compatible spindle configurations. Wet or dry operation allows flexibility depending on the grinding machine and coolant availability on site.

Compatibility

Designed as an OEM-style replacement or direct-fit superabrasive wheel for tool and cutter grinders accepting a 6-inch diameter, 1-1/4-inch arbor hole, Type 12V9 wheel configuration.

Installation Notes

Mounting and dressing of superabrasive wheels should be performed by qualified grinding machine operators familiar with ANSI B11.9 and relevant machine manufacturer guidelines. Always power down and lock out the grinder before mounting or changing wheels. Inspect the wheel for cracks or damage before installation and verify spindle speed does not exceed the wheel's rated maximum RPM. When operating wet, confirm coolant is flowing before engaging the workpiece to prevent thermal shock to the superabrasive layer.
