Norton 66253246793 Surface Grinding Wheel 60 Grit 14in

Product Description

The NORTON 66253246793 is a Type 1 straight surface grinding wheel engineered for precision stock removal on ferrous and non-ferrous metals. Built with aluminum oxide abrasive and a vitrified bond, it delivers consistent cut rates and wheel integrity across extended grinding cycles. The wheel measures 14 inches in diameter, 1 inch thick, with a 5-inch arbor hole, and carries a 60-grit, medium-grade (I hardness) specification. Rated at a maximum of 2,320 RPM, it is sized for surface grinders and CNC cutting tool machines used in production and toolroom environments. Licensed grinding machine operators and tool-and-die professionals are the primary installers and users.

This wheel is suited for surface grinding applications on 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. It performs on surface grinders, cylindrical grinders, and CNC cutting tool machines in both job-shop and production settings. The 60-grit medium grade makes it appropriate for general-purpose material removal where surface finish is secondary to stock removal rate. Non-porous construction and a vitrified bond support stable performance under coolant flood or dry grinding conditions.

Key Features

• Aluminum oxide abrasive with vitrified bond for consistent cut and long wheel life
• 60-grit medium grade suited for general-purpose stock removal on steels and cast iron
• Type 1 straight profile with no recess — direct mount to standard surface grinder spindles
• Non-porous wheel construction supports both wet and dry grinding setups
• Maximum rated speed of 2,320 RPM — never exceed this rating in operation
• Wide material compatibility including stainless, carbon steels, tool steels, aluminum, and iron grades

Compatibility

Designed for use with surface grinders, cylindrical grinders, and CNC cutting tool machines. Compatible material applications include 400 Series Stainless, Hard Carbon Steels, Soft Carbon Steels, Tool Steels, Aluminum, Cast Iron, Ductile Iron, and Gray Iron as stated in manufacturer specifications.

Installation Notes

Mounting and dressing of grinding wheels should be performed by qualified personnel following ANSI B11.9 and OSHA 29 CFR 1910.215 guarding requirements. Before mounting, inspect the wheel for cracks using a ring test — do not mount any wheel that produces a dull thud rather than a clear ring. Ensure the machine spindle speed does not exceed the 2,320 RPM maximum rating stamped on the wheel. Always install the correct blotters and flanges as specified by the grinder manufacturer before tightening the arbor nut.
