Norton 66253160137 Surface Grinding Wheel 10in 60 Grit

Product Description

The NORTON 66253160137 is a Type 1 straight surface grinding wheel designed for precision stock removal and surface finishing on a wide range of ferrous and non-ferrous metals. Built with an aluminum oxide abrasive grain and a vitrified bond, this wheel delivers consistent cut rate and form holding throughout its service life. It measures 10 inches in diameter, 3/4 inches thick, with a 3-inch arbor hole, and carries a 60 grit, medium grade (hardness code I) specification. Maximum operating speed is 2,485 RPM. The Series 32A designation indicates a specific aluminum oxide formulation suited for general-purpose precision grinding. Toolroom technicians, surface grinder operators, and machining professionals are the primary users of this wheel.

This wheel is intended for use on surface grinders, cylindrical grinders, and CNC cutting tool machines. It is well suited for grinding 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. The 60 grit medium grade combination makes it appropriate for applications that balance material removal rate with surface finish quality, such as flat surface grinding of machine components, toolroom work, and production grinding operations where moderate stock removal is required.

Key Features

• Aluminum oxide abrasive grain — effective on steels, tool steels, cast iron, and aluminum
• Vitrified bond provides rigidity and consistent cut rate with good form retention
• 60 grit medium grade balances material removal and surface finish quality
• Porous structure promotes coolant flow and chip clearance during grinding
• Series 32A specification (32A60-IVBE) for repeatable performance across production runs
• No recess, no taper — standard Type 1 straight wheel geometry for direct machine mounting

Compatibility

Designed for use with surface grinders, cylindrical grinders, and CNC cutting tool machines. Compatible material applications include 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 machine operator or toolroom technician following ANSI B7.1 safe mounting standards for abrasive wheels. Always inspect the wheel for cracks or chips before mounting and perform a ring test. Power down and lock out the grinder before changing wheels. Never exceed the 2,485 RPM maximum operating speed marked on the wheel.
