Norton 66253160769 Surface Grinding Wheel 60 Grit 10 in

Product Description

The NORTON 66253160769 is a Type 1 surface grinding wheel built for precision stock removal on ferrous and non-ferrous metals. It measures 10 inches in diameter, 1 inch thick, with a 3-inch arbor hole. The wheel is constructed from aluminum oxide abrasive bonded with a vitrified bond and carries a 60-grit, medium-grade (Hardness Code I) specification designated 32A60-IVBE. Maximum operating speed is 2,485 RPM. Licensed HVAC techs, machinists, and toolroom operators working with surface grinders and cylindrical grinders rely on this wheel for flat surface finishing and tool reconditioning. The gray, non-tapered, porous structure promotes coolant flow and reduces heat buildup during extended grinding passes.

This wheel is rated for use on 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. It is intended for installation on surface grinders and cylindrical grinders, as well as CNC cutting tool machines. The 10-inch diameter and 3-inch bore make it a common fit for mid-size production surface grinders found in job shops, toolrooms, and maintenance facilities handling a wide range of ferrous and non-ferrous workpieces.

Key Features

• Aluminum oxide abrasive — suited for steels, cast iron, aluminum, and stainless steel applications
• Vitrified bond with porous structure promotes coolant retention and reduces thermal loading
• 60-grit medium grade delivers a balance of stock removal rate and surface finish quality
• Hardness Code I (medium) maintains consistent wheel breakdown on a broad range of workpiece hardnesses
• Type 1 straight wheel profile with no recess — direct mounting on standard surface grinder spindles
• 2,485 RPM maximum operating speed rated for production surface grinding use

Compatibility

Designed for use with surface grinders, cylindrical grinders, and CNC cutting tool machines. Rated for 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 specialist 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 ANSI guidelines. Power down and lock out the grinder before mounting or removing the wheel. Never exceed the 2,485 RPM maximum speed rating stamped on the wheel blotter.
