Norton 66253043416 Surface Grinding Wheel 8in 60 Grit

Product Description

The NORTON 66253043416 is a Type 1 straight surface grinding wheel designed for precision material removal on ferrous and non-ferrous metals. Built with aluminum oxide abrasive and a vitrified bond, this wheel measures 8 inches in diameter, 1/4 inch thick, with a 1-1/4 inch arbor hole. The 60 grit, medium-grade (Hardness Code I) construction delivers controlled stock removal without excessive surface loading. Rated to 3600 RPM maximum, it suits production grinding applications where consistent finish and wheel integrity matter. Licensed machinists, tool-and-die workers, and maintenance technicians are the primary installers of this wheel.

This wheel is engineered for use on surface grinders, cylindrical grinders, and CNC cutting tool machines. It performs across a wide range of workpiece materials including 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. The vitrified bond provides rigidity and free-cutting action suited for flat surface grinding operations in both job-shop and production environments.

Key Features

• Aluminum oxide abrasive for versatile ferrous and non-ferrous metal grinding
• Vitrified bond delivers rigid, free-cutting wheel action
• 60 grit medium grade (Hardness Code I) for controlled stock removal
• Porous wheel structure promotes coolant flow and reduces heat buildup
• Type 1 straight profile with no recess and no taper for direct arbor mounting
• Series specification 32A60-IVBE for traceability and replacement matching

Compatibility

Rated for use with surface grinders, cylindrical grinders, and CNC cutting tool machines. Suitable for grinding 400 series stainless steel, hard carbon steels, soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron workpieces.

Installation Notes

Grinding wheel mounting and dressing must be performed by qualified personnel following ANSI B11.9 and OSHA 29 CFR 1910.215 standards. Always power down and lock out the grinder before mounting or removing a wheel. Inspect the wheel for cracks or chips using the ring test before installation, and never exceed the 3600 RPM maximum rated speed. Ensure the arbor hole, flanges, and blotters are compatible with this wheel diameter and thickness before operation.
