Norton 66252906907 Surface Grinding Wheel 7in 60 Grit

Product Description

The NORTON 66252906907 is a Type 5 recessed surface grinding wheel engineered for aggressive stock removal on hard ferrous and exotic metals. Built on a ceramic abrasive grain with a vitrified bond, this wheel delivers consistent cut rates and long wheel life on demanding materials including stainless steel, tool steels, titanium, super alloys, and cast and ductile iron. At 7 inches in diameter and 1 inch thick with an I hardness code and medium grade, it is rated for use at a maximum of 3600 RPM. The semi-friable ceramic grain self-sharpens under load, reducing the frequency of dressing cycles. Installation and operation require a licensed machinist or qualified grinding technician.

This wheel is designed for use on surface grinders and cylindrical grinders in industrial and toolroom environments. Typical applications include precision surface grinding of 400 series stainless steel, hard carbon steels, tool steels, titanium, super alloys, and gray, ductile, and cast iron. The porous structure and vitrified bond allow coolant penetration and efficient swarf evacuation, making this wheel well suited for wet grinding operations where heat control and surface finish are critical. The blue wheel color is characteristic of the SG ceramic grain series.

Key Features

• Ceramic abrasive grain for high material removal rates on hard and exotic alloys
• Vitrified bond with porous structure promotes coolant flow and reduces heat buildup
• Semi-friable grain self-sharpens, extending dress intervals between cycles
• Type 5 profile with one-side recess: 3 inch recess diameter, 0.5 inch recess depth
• I hardness code, medium grade for balanced wheel life and cut aggressiveness
• Compatible with surface grinders and cylindrical grinders up to 3600 RPM maximum

Compatibility

Designed for use with surface grinders and cylindrical grinders. Suitable for grinding 400 series stainless steel, hard carbon steels, tool steels, titanium, super alloys, cast iron, ductile iron, and gray iron as specified by the manufacturer.

Installation Notes

This wheel should be mounted and operated by a qualified machinist or grinding technician following ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels. Always power down and lock out the grinder before mounting or changing wheels. Inspect the wheel for cracks or chips before installation and perform a ring test to confirm structural integrity. Never exceed the maximum rated speed of 3600 RPM, and always use the correct flanges and blotters for the wheel bore size.
