The NORTON 66253364243 is a Type 1 surface grinding wheel engineered for precision stock removal on a wide range of ferrous and non-ferrous metals. Constructed with aluminum oxide abrasive and a vitrified bond, this wheel delivers consistent, free-cutting action with a coarse 46-grit profile and H hardness rating. It measures 14 inches in diameter, 1-1/2 inches thick, and carries a 5-inch arbor hole, making it suited for larger-capacity surface grinders and cylindrical grinders. Rated at a maximum of 1800 RPM, it is installed and operated by machinists and tool-and-die professionals working in production or job-shop environments.
This wheel is designed for surface grinding applications across a broad spectrum of materials including 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. Typical use scenarios include surface grinders, cylindrical grinders, and CNC cutting tool machines in both production and maintenance grinding operations. The porous structure of this wheel promotes coolant flow and chip clearance, reducing heat buildup during aggressive material removal passes.
Designed for use with surface grinders, cylindrical grinders, and CNC cutting tool machines. Compatible material applications include 400 series stainless steel, hard carbon steels, soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron.
Installation should be performed by a qualified machinist or grinding equipment operator following the machine manufacturer's wheel-mounting procedures and ANSI B11.9 safety guidelines for grinding machines. Always inspect the wheel for cracks or chips using the ring test before mounting, and never exceed the rated maximum of 1800 RPM. Power down and lock out the machine before changing wheels. Use appropriate blotters and flanges as required by the machine and wheel specifications.
