Norton 66253160778 Surface Grinding Wheel 60 Grit 10in

Product Description

The NORTON 66253160778 is a Type 1 straight surface grinding wheel engineered for precision stock removal on a range of ferrous and non-ferrous materials. Built with aluminum oxide abrasive and a vitrified bond, it delivers consistent, controlled cutting action across applications that demand dimensional accuracy. The wheel measures 10 inches in diameter, 1 inch thick, with a 3-inch arbor hole, and carries a 60-grit medium-grade specification suitable for general-purpose surface grinding. Maximum operating speed is 2485 RPM. Weighing approximately 6.1 pounds, it is sized for industrial surface and cylindrical grinders used in production and toolroom environments. Licensed grinding technicians and machinists are the primary installers.

This wheel is rated for use on 400 Series stainless steel, hard carbon steels, soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. It is designed for use on surface grinders, cylindrical grinders, and CNC cutting tool machines. The 60-grit medium grade balances material removal rate with surface finish quality, making it well suited to roughing and semi-finish passes on flat or cylindrical workpieces in both production shops and toolroom settings.

Key Features

• Aluminum oxide abrasive for reliable performance on steel, cast iron, and aluminum
• Vitrified bond provides rigidity and consistent wheel form throughout the wheel life
• 60-grit medium grade balances stock removal with achievable surface finish
• L hardness code (medium) helps maintain free-cutting action on a wide range of workpiece hardnesses
• Porous structure promotes coolant flow and chip clearance during wet or dry grinding
• Type 1 straight profile with no recess fits standard surface and cylindrical grinder spindle configurations
• Series designation 32A60-LVBE provides direct cross-reference for specification-controlled purchasing

Compatibility

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

Installation Notes

Mounting and dressing of grinding wheels should be performed by qualified personnel following ANSI B11.9 and OSHA 29 CFR 1910.215 guidelines. Before mounting, ring-test the wheel for cracks and verify that the machine spindle speed does not exceed the 2485 RPM maximum marked on the wheel. Power down and lock out the grinder before changing wheels. Never exceed the rated maximum RPM, and always use the correct blotters and flanges supplied or approved by the machine manufacturer.
