Norton 66253262511 Surface Grinding Wheel 12in 60 Grit

Product Description

The NORTON 66253262511 is a Type 1 surface grinding wheel engineered for high-performance stock removal on hard ferrous metals and exotic alloys. Built with ceramic abrasive grain and a vitrified bond, this wheel operates at a maximum of 2070 RPM and delivers consistent, controlled cutting action across demanding applications. At 12 inches in diameter, 1 inch thick, and with a 5-inch arbor hole, it fits standard surface and cylindrical grinder spindles used in production and tool-room environments. The medium grade and I hardness rating provide a balanced combination of wheel life and free cutting action. Weighing 7.98 pounds, it is a substantial wheel suited for sustained grinding passes.

This wheel is rated for use on 400 series stainless steel, hard carbon steels, tool steels, titanium, super alloys, cast iron, ductile iron, and gray iron. It is designed for use with CNC cutting tool machines, cylindrical grinders, and surface grinders. The porous, semi-friable ceramic grain structure supports coolant flow and reduces heat buildup during aggressive material removal cycles, making it well suited for precision surface grinding in both job shop and production environments.

Key Features

• Ceramic abrasive grain for aggressive, consistent stock removal on hard and exotic alloys
• Vitrified bond with porous structure promotes coolant penetration and heat dissipation
• Medium grade, I hardness (5SG60-IVS specification) for balanced wheel life and cutting efficiency
• Type 1 flat wheel profile, no recess, fits standard surface and cylindrical grinder arbors
• Semi-friable grain continuously exposes fresh cutting edges during use
• Rated for 400 series stainless, tool steels, titanium, super alloys, and iron grades

Compatibility

Designed for use with CNC cutting tool machines, cylindrical grinders, and surface grinders. Rated for grinding 400 series stainless steel, hard carbon steels, tool steels, titanium, super alloys, cast iron, ductile iron, and gray iron.

Installation Notes

Installation should be performed by a qualified grinding machine operator or maintenance technician. Power down and lock out the grinder before mounting or removing any wheel. Inspect the wheel for cracks or chips before mounting and perform a ring test per ANSI B7.1 guidelines. Verify the machine spindle speed does not exceed the 2070 RPM maximum rating stamped on the wheel before operation.
