Norton 66253262504 Surface Grinding Wheel 60 Grit 12 in

Product Description

The NORTON 66253262504 is a Type 1 surface grinding wheel engineered for precision stock removal on ferrous and exotic metals. Built on a ceramic abrasive grain with a vitrified bond, this wheel delivers consistent cut rates and controlled wear, making it a go-to choice for surface grinders and cylindrical grinders in production and toolroom environments. The wheel measures 12 inches in diameter, 1 inch thick, with a 3-inch arbor hole. Grit is 60 with a J hardness code, placing it in the medium grade range. Maximum operating speed is 2070 RPM. Licensed grinding techs and toolroom machinists are the typical installers.

This wheel is suited for flat surface grinding applications across a wide range of demanding materials including 400 series stainless steel, hard carbon steels, tool steels, titanium, super alloys, cast iron, ductile iron, and gray iron. It is rated for use on CNC cutting tool machines, cylindrical grinders, and surface grinders. The porous, semi-friable ceramic structure supports free cutting action and resists loading, which is particularly valuable when working heat-sensitive alloys and hardened tool steels.

• 3-inch arbor hole accommodates common production grinder flanges
• Rated to 2070 RPM maximum operating speed

Compatibility

Designed for use with CNC cutting tool machines, cylindrical grinders, and surface grinders. Suitable for grinding 400 series stainless steel, hard carbon steels, tool steels, titanium, super alloys, cast iron, ductile iron, and gray iron. Series designation is 5SG Type 1 with specification code 5SG60-JVS.

Installation Notes

Grinding wheel mounting and dressing must be performed by a qualified grinding machine operator following ANSI B11.9 and OSHA 29 CFR 1910.215 safety standards. Inspect the wheel for cracks or chips using a ring test before mounting. Never exceed the 2070 RPM maximum operating speed marked on the wheel. Power down and lock out the grinder before removing or installing any wheel.
