Norton 66253043426 Surface Grinding Wheel 100 Grit

Product Description

The NORTON 66253043426 is a Type 1 surface grinding wheel designed for precision material removal on a range of ferrous and non-ferrous metals. Built with aluminum oxide abrasive and a vitrified bond, this wheel delivers consistent stock removal and a fine finish at a maximum operating speed of 3600 RPM. It measures 8 inches in diameter with a 1/4 inch face width and a 1-1/4 inch arbor hole. The vitrified bond structure is porous, promoting cool cutting and reduced glazing during extended runs. At 1.04 pounds, it is well suited for bench-mounted and CNC surface grinder setups where dimensional control matters. Grinding professionals and machinists are the primary installers and operators.

This wheel is rated for use on 400 series stainless steel, hard carbon steels, soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. It is intended for use with surface grinders, cylindrical grinders, and CNC cutting tool machines. The fine grade and 100 grit rating make it appropriate for finishing passes and light stock removal rather than aggressive rough grinding. The 32A Type 1 series designation identifies it as a straight wheel with no recess and no taper, making it compatible with standard surface grinder spindle setups.

Compatibility

Designed for use with surface grinders, cylindrical grinders, and CNC cutting tool machines. Suitable for material applications including 400 series stainless steel, hard carbon steels, soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron.

Installation Notes

Grinding wheel mounting and dressing should be performed by a qualified machinist or grinding professional familiar with ANSI B11.9 safety standards for grinding machines. Always power down and de-energize the machine before mounting or changing wheels. Inspect the wheel for cracks or chips using the ring test before installation, and never exceed the maximum rated RPM of 3600. Use appropriate flanges and blotters as specified by the machine manufacturer and applicable safety standards.
