Norton 66253246835 Surface Grinding Wheel 7in 46 Grit

Product Description

The NORTON 66253246835 is a Type 5 vitrified surface grinding wheel engineered for precision stock removal on soft carbon steels and tool steels. Measuring 7 inches in diameter and 1 inch thick with a 1-1/4 inch arbor hole, this wheel uses aluminum oxide abrasive bonded in a vitrified matrix. The 46 grit, J hardness (coarse grade, semi-friable) construction delivers aggressive material removal while maintaining consistent wheel breakdown on softer workpiece materials. A single-side recess of 1/2 inch deep and 3 inches in diameter reduces wheel weight and improves coolant access at the grinding face. Rated to a maximum of 3600 RPM.

This wheel is suited for use on cylindrical grinders and surface grinders in tool rooms, maintenance shops, and production environments. The Gemini Precision Vitrified series is designed for applications requiring controlled wheel wear and repeatable surface finish on soft carbon steels and tool steels. The blue and gray wheel color is consistent with NORTON Gemini vitrified bonds. This is a single-piece package appropriate for bench or floor grinding machine setups where a Type 5 recessed wheel geometry is specified.

Compatibility

Designed for use with cylindrical grinders and surface grinders where a Type 5 recessed wheel with a 1-1/4 inch arbor hole is required. Suitable for grinding soft carbon steels and tool steels.

Installation Notes

Grinding wheel installation and dressing should be performed by qualified personnel following ANSI B11.9 and OSHA 1910.215 safe grinding practices. Always inspect the wheel for cracks or chips before mounting and perform a ring test. Power down and lock out the grinder before changing wheels. Never exceed the 3600 RPM maximum speed rating marked on the wheel.
