Norton 66253043716 Surface Grinding Wheel 8in 46 Grit

Product Description

The NORTON 66253043716 is a Type 1 surface grinding wheel designed for precision stock removal and surface finishing on ferrous and non-ferrous metals. Constructed with aluminum oxide abrasive and a vitrified bond, this wheel measures 8 inches in diameter, 1/2 inch thick, and carries a 1-1/4 inch arbor hole. The 46-grit, coarse-grade specification makes it well suited for aggressive material removal passes where surface finish is secondary to stock removal rate. Maximum operating speed is rated at 3600 RPM. The gray vitrified wheel is porous in structure, which aids in chip clearance and coolant flow during wet grinding operations. Licensed machinists, tool-and-die makers, and grinding machine operators are the primary installers and users of this wheel.

This wheel is intended for use on surface grinders, cylindrical grinders, and CNC cutting tool machines in both shop and production environments. Stated material applications include 400 Series stainless steel, hard carbon steels, soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. The coarse grit and medium hardness rating make it a practical choice for initial material removal cycles on tough ferrous alloys. It is packaged individually with a minimum order quantity of one unit.

Key Features

• Aluminum oxide abrasive with vitrified bond for consistent cutting action and wheel integrity
• 46 grit, coarse grade for high stock removal on ferrous and non-ferrous metals

• Maximum operating speed of 3600 RPM
• No recess, no taper — standard Type 1 flat wheel profile
• Specification designation 32A46-KVBE for direct cross-reference and replacement ordering

Compatibility

Rated for use with surface grinders, cylindrical grinders, and CNC cutting tool machines. Confirmed material applications include 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 qualified personnel following ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels. Always power down and lock out the machine before mounting or removing a wheel. Inspect the wheel for cracks or chips before installation and perform a ring test per manufacturer and ANSI guidelines. Never exceed the rated maximum RPM of 3600 under any operating condition.
