Norton 66253160405 Surface Grinding Wheel 60 Grit 10 in

Product Description

The NORTON 66253160405 is a Type 1 surface grinding wheel engineered for demanding material removal on hard ferrous metals and alloys. Built with ceramic abrasive grain and a vitrified bond, this wheel delivers consistent cut rate and form retention across extended production runs. It measures 10 inches in diameter, 1 inch thick, with a 3-inch arbor hole, and is rated to a maximum of 2485 RPM. The 60-grit, K-hardness (medium) specification suits aggressive stock removal while maintaining controlled surface finish. Licensed tradespeople operating surface grinders and CNC tool-grinding equipment are the primary installers and operators of this wheel.

This wheel is suited for surface grinding, cylindrical grinding, and CNC cutting tool machine applications. Its ceramic grain and semi-friable structure make it a strong match for difficult-to-grind materials including 400 series stainless steel, hard carbon steels, tool steels, titanium, super alloys, cast iron, ductile iron, and gray iron. The porous, vitrified bond structure promotes coolant flow and chip clearance, reducing heat buildup at the workpiece during heavy-duty grinding cycles in both job shop and production environments.

Key Features

• Ceramic abrasive grain with vitrified bond for consistent cut rate and wheel life
• Semi-friable grain structure self-sharpens during use, reducing dress frequency
• Porous wheel body promotes coolant penetration and chip evacuation
• 60 grit, K hardness (medium grade) for aggressive stock removal on hard alloys
• Type 1 straight wheel profile with no recess, compatible with standard surface and cylindrical grinder flanges
• Rated for use on 400 series stainless, tool steels, titanium, super alloys, and cast iron families

Compatibility

Designed for use with surface grinders, cylindrical grinders, and CNC cutting tool machines. Rated material applications include 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-KVS.

Installation Notes

Grinding wheel mounting and dressing must be performed by qualified personnel following ANSI B7.1 safety standards for abrasive wheel use. Before mounting, inspect the wheel for cracks using the ring test and verify that the machine spindle speed does not exceed the wheel's 2485 RPM maximum rating. Always power down and lock out the grinder before changing wheels, and use properly sized, undamaged flanges with blotter pads. Eye and face protection, along with appropriate guarding, is required during all grinding operations.
