Norton 66253364104 Surface Grinding Wheel 60 Grit Type 5

Product Description

The NORTON 66253364104 is a Type 5 recessed surface grinding wheel engineered for demanding material removal on ferrous metals and hard alloys. Built with a ceramic abrasive grain and a vitrified bond, it delivers consistent cut rates and long wheel life on hard-to-grind materials including stainless steel, tool steels, titanium, super alloys, and various grades of cast iron. The wheel measures 14 inches in diameter and 1-1/2 inches thick, with a 5-inch arbor hole and a one-side recess of 1/2 inch depth at 8 inches in diameter. At 60 grit with an I hardness code and medium grade classification, it is suited for aggressive stock removal while still leaving a controlled surface finish. The specification designation is 5SG60-IVS. Rated at a maximum of 1800 RPM.

This wheel is designed for use on surface grinders and cylindrical grinders in industrial and production-shop environments. Typical applications include grinding 400 series stainless steel, hard carbon steels, tool steels, titanium, super alloys, and cast iron including ductile and gray iron grades. The porous, semi-friable ceramic grain structure helps prevent heat buildup during heavy-duty grinding cycles, making it a practical choice for shops that process hard alloys or heat-sensitive workpieces. It is best suited for professional machinists, tool and die shops, and maintenance grinding operations.

• Rated material applications include 400 series stainless, tool steels, titanium, super alloys, and cast and ductile iron

Compatibility

Designed for use with surface grinders and cylindrical grinders. Rated material applications include 400 Series Stainless, Hard Carbon Steels, Tool Steels, Titanium, Super Alloys, Cast Iron, Ductile Iron, and Gray Iron.

Installation Notes

Grinding wheel mounting and dressing should be performed by a qualified machinist or grinding technician following ANSI B11.9 and OSHA 29 CFR 1910.215 safety standards. Always inspect the wheel for cracks or chips before mounting and perform a ring test. Ensure the grinder is fully de-energized and locked out before changing wheels. Never exceed the rated maximum spindle speed of 1800 RPM.
