Norton 66253043651 Surface Grinding Wheel 8in 60 Grit

Product Description

The NORTON 66253043651 is a Type 1 surface grinding wheel engineered for aggressive stock removal on ferrous and exotic metals. Built with ceramic abrasive grain and a vitrified bond, it delivers consistent cut rates and thermal resistance across extended grinding sessions. The wheel measures 8 inches in diameter, 1/2 inch thick, with a 1-1/4 inch arbor hole, and runs at a maximum of 3600 RPM. The G hardness code and medium grade designation make it well-suited to precision surface grinding applications where wheel life and form retention are priorities. It carries a blue color designation and a semi-friable grain structure that self-sharpens under load.

This wheel is designed for use on surface grinders, cylindrical grinders, and CNC cutting tool machines in production and toolroom environments. Rated material applications include 400 Series stainless steel, hard carbon steels, tool steels, titanium, super alloys, cast iron, ductile iron, and gray iron. It is appropriate for both job shop and manufacturing floor use where consistent finish quality on difficult materials is required. Machinists and tool grinders in industrial maintenance, fabrication, and precision machining shops are the primary installers.

Key Features

• Ceramic abrasive grain with semi-friable structure for self-sharpening behavior under grinding pressure
• Vitrified bond provides rigidity and coolant compatibility for wet or dry grinding
• Type 1 straight wheel profile fits standard surface and cylindrical grinder spindles
• 60 grit medium grade balances aggressive material removal with acceptable surface finish
• Rated for 400 Series stainless, tool steels, titanium, super alloys, and cast and ductile iron
• Porous wheel structure promotes chip clearance and reduces heat buildup at the workpiece

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 is 5SG Type 1 with specification code 5SG60-GVSP.

Installation Notes

Grinding wheel mounting and dressing must be performed by qualified machinists or tool grinders following ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels. Always inspect the wheel for cracks or chips before mounting and perform a ring test per manufacturer and ANSI guidelines. Power down and lockout the grinder before changing wheels, and confirm the machine spindle speed does not exceed the 3600 RPM maximum rating marked on the wheel. Use appropriate flanges, blotters, and arbor hardware specified for Type 1 straight wheels.
