Norton 66253044101 Surface Grinding Wheel 8 in 60 Grit

Product Description

The NORTON 66253044101 is a Type 1 surface grinding wheel designed for precision material removal on hard ferrous metals and specialty alloys. Built with a ceramic abrasive grain and vitrified bond, this wheel delivers consistent stock removal and extended wheel life. It measures 8 inches in diameter by 3/4 inches thick with a 1-1/4 inch arbor hole, and is rated at a maximum of 3600 RPM. The 60 grit, Medium grade (Hardness Code I) construction is suited for aggressive yet controlled grinding passes on production and toolroom applications. Licensed machinists, tool-and-die makers, and industrial maintenance technicians are the primary installers and operators.

This wheel is well suited for surface grinding and cylindrical grinding operations on 400 Series stainless steel, hard carbon steels, tool steels, titanium, super alloys, cast iron, ductile iron, and gray iron. It is compatible with surface grinders, cylindrical grinders, and CNC cutting tool machines. The porous, semi-friable ceramic grain structure supports cool cutting action, making it especially effective on heat-sensitive materials such as titanium and high-alloy tool steels.

Key Features

• Ceramic abrasive grain for high material removal rates on hard and exotic alloys
• Vitrified bond provides rigidity and precise form holding during grinding passes
• 60 grit, Medium grade (Hardness Code I) balances cut rate and surface finish
• Porous structure promotes coolant flow and reduces heat buildup at the workpiece
• Semi-friable grain continuously self-sharpens to maintain cutting efficiency
• Rated to 3600 RPM maximum operating speed

Compatibility

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

Installation Notes

Mounting and dressing of grinding wheels must be performed by qualified personnel following ANSI B11.9 and applicable OSHA standards for abrasive wheel machinery. Always inspect the wheel for cracks or chips before mounting and perform a ring test. Guard the wheel to the machine manufacturer specifications and never exceed the rated maximum RPM. Power down and lock out the machine before changing wheels.
