Norton 66252838314 Type 2 Grinding Wheel 6 in 80 Grit

Product Description

The NORTON 66252838314 is a Type 2 aluminum oxide grinding wheel designed for precision tool grinding and surface grinding applications. The wheel measures 6 inches in diameter, 1 inch thick, with a 1-1/4 inch arbor hole. It carries an 80 grit medium-grade abrasive specification and a vitrified bond, which provides rigidity and free-cutting action during use. The hardness code H rates this wheel as soft on the industry scale, making it well-suited for grinding harder workpiece materials. Maximum operating speed is rated at 3,600 RPM. This wheel is white in color and is friable, meaning the abrasive breaks down progressively to expose fresh cutting edges. It is intended for use by machinists, tool and die technicians, and grinding machine operators.

This wheel is typically used in bench or pedestal grinder setups for sharpening high-speed steel tooling, reconditioning cutting edges, and light surface grinding. The vitrified bond and soft H hardness grade make it appropriate for applications where heat buildup must be controlled and consistent cut quality is required. The non-porous structure and aluminum oxide abrasive make this a standard choice for ferrous metal grinding in tool rooms and maintenance shops.

Compatibility

Designed as an OEM-style replacement or direct-fit grinding wheel for bench and pedestal grinders accepting a Type 2 wheel with a 6 inch diameter, 1 inch face width, and 1-1/4 inch arbor hole.

Installation Notes

Installation should be performed by a qualified machinist or grinding equipment operator. Always power down and lock out the grinder before mounting or removing a wheel. Inspect the wheel for cracks or chips before installation and perform a ring test per ANSI B7.1 guidelines. Never exceed the 3,600 RPM maximum rated speed marked on the wheel.
