Norton 66252941206 Surface Grinding Wheel 46 Grit

Product Description

The NORTON 66252941206 is a Type 1 surface grinding wheel engineered for precision stock removal on ferrous and non-ferrous metals. Built with aluminum oxide abrasive and a vitrified bond, it delivers consistent cut rate and form retention across extended use cycles. The wheel measures 7 inches in diameter, 1/2 inch thick, with a 1-1/4 inch arbor hole, and is rated for a maximum of 3600 RPM. Hardness code I places it in the medium range, making it well suited to applications where wheel breakdown and workpiece finish must stay in balance. Licensed machinists, tool and die makers, and surface grinder operators are the primary users.

This wheel is designed for use on surface grinders, cylindrical grinders, and CNC cutting tool machines in both shop and industrial environments. Verified material applications include 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. The coarse 46 grit designation supports aggressive material removal rather than finish grinding. Wet operation is supported, which helps control heat buildup during heavy-duty cuts on hardened or heat-sensitive workpieces.

Key Features

• Aluminum oxide abrasive with vitrified bond for consistent cut and form stability
• 46 grit coarse grade optimized for high material removal rates
• Medium hardness (code I) balances wheel wear against workpiece surface finish
• Rated to 3600 RPM maximum operating speed
• Porous structure supports wet grinding and coolant flow
• Specification designation 32A46-IVBEP for direct cross-reference

Compatibility

Verified compatible 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.

Installation Notes

Installation should be performed by a qualified machinist or grinding machine operator following the machine manufacturer's mounting procedures. Always inspect the wheel for cracks or chips before mounting and perform a ring test per ANSI B11.9 guidelines. Power down and lock out the machine before changing wheels. Never exceed the 3600 RPM maximum speed rating marked on the wheel, and ensure the arbor hole fits the spindle without forcing.
