Norton 66253044173 Surface Grinding Wheel 8in 60 Grit

Product Description

The NORTON 66253044173 is a Type 1 surface grinding wheel designed for precision stock removal on ferrous and non-ferrous materials in industrial and tool-room applications. The wheel measures 8 inches in diameter by 3/4 inches thick with a 1-1/4 inch arbor hole. It is made from aluminum oxide abrasive bonded with a vitrified bond, graded at 60 grit and K hardness (medium), and rated for a maximum of 3600 RPM. The porous structure of the vitrified bond promotes coolant flow and chip clearance during grinding passes. Licensed grinding technicians and machinists install and dress this wheel as part of routine surface and cylindrical grinding operations.

This wheel is suited for surface grinding, cylindrical grinding, and CNC cutting tool machine applications. Compatible material applications include 400 series stainless steel, hard carbon steels, soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. It is a practical choice for tool rooms and production floor environments where consistent stock removal and surface finish are required across a range of ferrous and non-ferrous workpieces.

Compatibility

Designed 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

Installation should be performed by a qualified machinist or grinding technician following applicable ANSI B11 and OSHA grinding safety standards. Inspect the wheel for cracks or chips before mounting — never mount a damaged wheel. Power down and lock out the grinder before changing wheels, and always perform a ring test prior to installation. Run the mounted wheel at operating speed for at least one minute behind a guard before bringing it into contact with a workpiece.
