Norton 66253246913 Surface Grinding Wheel 14in 46 Grit

Product Description

The NORTON 66253246913 is a Type 1 vitrified aluminum oxide surface grinding wheel engineered for aggressive material removal on ferrous and non-ferrous metals. At 14 inches in diameter, 1 inch thick, with a 5-inch arbor hole, this wheel runs at a maximum of 2320 RPM. The 46-grit, H-hardness (coarse grade) specification makes it well suited for high-stock-removal passes where surface finish is secondary to speed and efficiency. The vitrified bond provides consistent cutting action and good wheel breakdown characteristics throughout the wheel life. At 11.43 pounds, the wheel carries the mass needed to maintain contact pressure on large workpieces without flex.

This wheel is designed for use on surface grinders, cylindrical grinders, and CNC cutting tool machines in production and job-shop environments. Rated material applications include 400 Series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. It is a non-porous, non-tapered, flat wheel with no recess, making it straightforward to mount and dress. The Series 32A designation identifies it within the NORTON product family for this wheel specification.

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 workpieces.

Installation Notes

Installation should be performed by a qualified grinding machine operator or maintenance technician following ANSI B7.1 safe mounting procedures. Inspect the wheel for cracks or chips before mounting and perform a ring test; never mount a damaged wheel. Power down and lock out the machine before changing wheels. Always verify that the machine spindle speed does not exceed the 2320 RPM maximum rating marked on the wheel, and dress the wheel before the first cut on a new mount.
