Norton 66253043415 Surface Grinding Wheel 8in 60 Grit

Product Description

The NORTON 66253043415 is a Type 1 surface grinding wheel designed for material removal and finishing on ferrous and non-ferrous metals. Built with aluminum oxide abrasive and a vitrified bond, this wheel delivers consistent, controlled cutting action across a range of hard and soft metals. It measures 8 inches in diameter, 1/4 inch thick, with a 1-1/4 inch arbor hole. The 60-grit, medium-grade specification and H hardness code make it well suited for stock removal where a balance of cut rate and surface finish is required. Rated to 3600 RPM. Wheel color is gray. Conforms to the 32A60-HVBE specification.

This wheel is used in surface grinding, cylindrical grinding, and CNC cutting tool machine applications. It is appropriate for both production and maintenance grinding on a wide range of materials including 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. The porous, vitrified structure promotes coolant flow and chip clearance, reducing heat buildup during extended grinding passes on a surface grinder or cylindrical grinder.

Key Features

• Aluminum oxide abrasive for use on ferrous and non-ferrous metals including stainless, carbon steels, tool steels, and cast iron
• Vitrified bond with porous structure improves coolant penetration and chip evacuation
• 60 grit, medium grade provides balanced stock removal and surface finish control
• H hardness code (32A60-HVBE specification) for consistent wheel performance across compatible machines
• Type 1 flat wheel profile with no recess, no taper — straightforward mounting on standard arbors
• 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, soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron.

Installation Notes

Installation should be performed by a qualified grinding machine operator or maintenance technician. Before mounting, power down and lock out the machine per OSHA lockout/tagout procedures. Inspect the wheel for cracks or chips before mounting — never install a damaged wheel. Ensure the machine spindle speed does not exceed the 3600 RPM maximum rating marked on the wheel, and conduct a ring test prior to use per ANSI B11.9 grinding safety guidelines.
