Norton 66252916212 Surface Grinding Wheel 7in 60 Grit

Product Description

The NORTON 66252916212 is a Type 1 surface grinding wheel designed for precision material removal on hard ferrous metals and specialty alloys. Built with a ceramic abrasive grain and a vitrified bond, it delivers consistent stock removal and long wheel life. The wheel measures 7 inches in diameter, 0.5 inches thick, with a 1-1/4 inch arbor hole, and is rated for a maximum of 3600 RPM. At 60 grit with a G hardness code and medium grade, it is suited for aggressive cutting action while maintaining controlled surface finishes. The porous, semi-friable structure promotes cool cutting and efficient swarf clearance.

This wheel is intended for use on surface grinders, cylindrical grinders, and CNC cutting tool machines in professional shop environments. It is designed to grind 400 series stainless steel, hard carbon steels, tool steels, titanium, super alloys, cast iron, ductile iron, and gray iron. It supports both wet and dry operation, making it adaptable to coolant-equipped or dry-grind setups. Typical users include tool-and-die machinists, maintenance shops, and production grinding operations working with high-alloy or high-hardness workpieces.

Key Features

• Ceramic abrasive grain for high material removal rates on hard and specialty alloys
• Vitrified bond provides rigidity, porosity, and consistent wheel performance
• Porous, semi-friable structure promotes cool cutting and swarf evacuation
• Rated for wet and dry operation — compatible with flood coolant or dry grinding
• Type 1 flat wheel geometry with no recess — straight mounting profile
• Series 3SG Type 1, specification 3SGR60-GVP2, purple wheel color for easy grade identification

Compatibility

Designed for use with surface grinders, cylindrical grinders, and CNC cutting tool machines. Suitable for grinding 400 series stainless steel, hard carbon steels, tool steels, titanium, super alloys, cast iron, ductile iron, and gray iron. Arbor hole size of 1-1/4 inches fits standard spindle configurations for this wheel diameter class.

Installation Notes

Installation should be performed by a qualified machinist or grinding machine operator. Before mounting, inspect the wheel for cracks or chips using the ring test; never mount a damaged wheel. Power down and lock out the grinder before changing wheels, and ensure the machine spindle speed does not exceed the 3600 RPM maximum rated speed stamped on the wheel. Follow ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels during mounting and operation.
