Norton 66252836405 Surface Grinding Wheel 80 Grit 6 in

Product Description

The NORTON 66252836405 is a Type 1 straight surface grinding wheel built for precision stock removal on ferrous and non-ferrous metals. It measures 6 inches in diameter, 1/2 inch thick, with a 1-1/4 inch arbor hole. The abrasive is aluminum oxide with a vitrified bond, rated at medium grade and J hardness. Specification code 32A80-JVBE identifies the exact wheel formulation. The porous structure promotes cool cutting and chip clearance during extended surface, cylindrical, and CNC tool grinding operations. Rated to 4140 RPM maximum. At 1.09 pounds, this wheel is well-suited to bench and production grinder spindles.

This wheel is designed for use on surface grinders, cylindrical grinders, and CNC cutting tool machines in both shop and production environments. It is suited for grinding 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. The 80 grit, medium-grade aluminum oxide abrasive strikes a balance between material removal rate and surface finish quality, making it a practical choice for tool rooms, machine shops, and maintenance grinding applications.

Compatibility

Designed for use with surface grinders, cylindrical grinders, and CNC cutting tool machines. Suitable for grinding 400 series stainless steel, hard carbon steels, soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. The 1-1/4 inch arbor hole fits standard spindle configurations on these machine types.

Installation Notes

Grinding wheel mounting and dressing should be performed by a qualified machinist or grinding equipment operator following ANSI B11.9 and OSHA 29 CFR 1910.215 standards. Always inspect the wheel for cracks or chips before mounting and perform a ring test. Machine must be powered off and locked out before changing wheels. Never exceed the 4140 RPM maximum speed rating marked on the wheel or its packaging.
