Norton 66253363932 Surface Grinding Wheel 60 Grit 14in

Product Description

The NORTON 66253363932 is a Type 1 straight surface grinding wheel engineered for precision stock removal and surface finishing on ferrous and non-ferrous metals. Built with aluminum oxide abrasive and a vitrified bond, it delivers consistent cut rate and long wheel life under production grinding conditions. The wheel measures 14 inches in diameter, 1 inch thick, with a 5-inch arbor hole, and is rated at a maximum of 1800 RPM. At 60 grit and K hardness (medium grade), it strikes a balance between aggressive material removal and controlled surface finish. Grinding wheel technicians and machinists install and true these wheels on surface grinders and cylindrical grinders in job shop and manufacturing environments.

This wheel is suited for surface grinding applications on a wide range of workpiece materials, including 400 series stainless steel, hard and 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 vitrified bond and porous structure allow coolant penetration and chip clearance, making it effective in both wet and dry grinding setups where consistent material removal is required across production runs.

Key Features

• Aluminum oxide abrasive for reliable performance on steels, cast iron, and aluminum
• Vitrified bond with porous structure for coolant flow and chip clearance
• 60 grit, K hardness (medium grade) for balanced stock removal and finish quality
• Type 1 straight wheel profile, no recess, not tapered
• Rated to 1800 RPM maximum operating speed
• Series designation 32A60-KVBE for direct specification cross-reference

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, as specified by the manufacturer.

Installation Notes

Grinding wheel installation and dressing must be performed by a qualified machinist or grinding technician following ANSI B11.9 and OSHA 29 CFR 1910.215 safety standards. Always inspect the wheel for cracks or chips using the ring test before mounting, and never exceed the marked maximum RPM of 1800. Power down and lock out the grinder before changing wheels. Proper flange size, wheel blotters, and arbor fit must be confirmed prior to running the wheel.
