Norton 66253044753 Surface Grinding Wheel 8in 60 Grit

Product Description

The NORTON 66253044753 is a Type 5 surface grinding wheel engineered for use on surface grinders and cylindrical grinders in metalworking applications. The wheel measures 8 inches in diameter and 1 inch thick, with a 1-1/4 inch arbor hole and a one-side recess measuring 3-1/4 inches in diameter and 1/2 inch deep. The abrasive material is aluminum oxide bonded with a vitrified bond, graded at 60 grit with a medium hardness rating (Hardness Code I). The wheel is porous, which aids in coolant retention and chip clearance during grinding. This wheel is used by machinists, toolroom technicians, and maintenance grinding professionals working with ferrous and non-ferrous metals.

The NORTON 66253044753 is suited for surface grinding and cylindrical grinding operations on 400 series stainless steel, hard carbon steels, soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. It fits standard surface grinder and cylindrical grinder spindle configurations that accept a 1-1/4 inch arbor bore. The Type 5 recessed profile is designed to provide clearance for flanges and grinding arbors in common machine setups. This makes it a practical choice for both production floor environments and toolroom applications.

Compatibility

Designed for use with surface grinders and cylindrical grinders that accept a Type 5 wheel with a 1-1/4 inch arbor bore. Suitable for grinding 400 series stainless steel, hard carbon steels, soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron.

Installation Notes

Installation should be performed by a qualified machinist or grinding equipment operator. Before mounting, inspect the wheel for cracks or chips using the ring test. Ensure the machine spindle speed does not exceed the wheel's 3,600 RPM maximum rating. Follow ANSI B7.1 safety standards for the mounting, guarding, and use of abrasive wheels, and always dress the wheel before beginning a new grinding operation.
