Norton 66253246872 Surface Grinding Wheel 60 Grit 14 in

Product Description

The NORTON 66253246872 is a Type 5 vitrified aluminum oxide surface grinding wheel built for heavy-duty stock removal on metalworking applications. Measuring 14 inches in diameter and 1.5 inches thick with a 5-inch arbor hole, this wheel carries a 60 grit, medium-grade (I hardness) specification and is rated to a maximum of 2,320 RPM. The vitrified bond delivers consistent cutting action and thermal stability under sustained grinding loads. Weighing 11.43 pounds, it is sized for industrial surface and cylindrical grinders. Machinists, tool-and-die technicians, and grinding specialists are the primary installers of this wheel.

This wheel is designed for use on surface grinders and cylindrical grinders handling a wide range of ferrous and non-ferrous metals. Rated material applications include 400 Series stainless steel, hard carbon steels, soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. The 32A series designation identifies the aluminum oxide abrasive formulation. The one-side recessed profile (Type 5) with a 0.5-inch recess depth and 8-inch recess diameter allows for proper wheel-to-workpiece clearance on recessed-hub mounting configurations.

Installation Notes

Wheel mounting should be performed by a qualified machinist or grinding equipment operator following ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels. Always inspect the wheel for cracks or damage before mounting, and conduct a ring test prior to installation. Power down and lock out the grinder before changing wheels. Never exceed the maximum operating speed of 2,320 RPM marked on the wheel.
