Norton 66253246822 Surface Grinding Wheel 7in 46 Grit

Product Description

The NORTON 66253246822 is a Type 5 recessed surface grinding wheel designed for stock removal and finish grinding on ferrous and non-ferrous metals. Constructed from aluminum oxide abrasive with a vitrified bond, it measures 7 inches in diameter and 3/4 inches thick with a 1-1/4 inch arbor hole and a one-side recess of 1/4 inches deep by 3 inches in diameter. The 46 grit, H hardness coarse grade is optimized for aggressive material removal while maintaining wheel integrity at speeds up to 3600 RPM. Licensed HVAC, plumbing, and industrial maintenance technicians will find this wheel suited to high-production grinding operations on a range of common metals.

This wheel is rated for use on 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. It is compatible with cylindrical grinders and surface grinders in both shop and field maintenance environments. The coarse 46 grit designation makes it appropriate for rapid material removal rather than fine finishing passes. The non-porous vitrified bond provides consistent abrasive exposure throughout the wheel life, making it a reliable choice for production grinding tasks in fabrication and maintenance shops.

Installation Notes

Wheel mounting should be performed by a qualified operator following ANSI B11.9 and OSHA 29 CFR 1910.215 safety standards for abrasive wheel machinery. Always ring-test the wheel before mounting and inspect for cracks or damage. Power down and lock out the grinder before changing wheels. Never exceed the maximum rated RPM of 3600 under any operating condition.
