Norton 66253043757 Surface Grinding Wheel 8in 60 Grit

Product Description

The NORTON 66253043757 is a Type 1 surface grinding wheel designed for precision flat-surface and tool grinding applications. Built from aluminum oxide abrasive with a vitrified bond, this wheel measures 8 inches in diameter, 1/2 inch thick, with a 1-1/4 inch arbor hole. It carries a 60-grit, medium-grade designation and a hardness code of I, making it well-suited for moderate material removal on soft carbon steels, tool steels, and super alloys. The semi-friable grain structure allows controlled breakdown during use, helping maintain a consistent cut and surface finish. Rated at 3600 RPM maximum, it is a standard choice for surface and cylindrical grinding setups.

This wheel is used in both shop and production environments where flat-surface grinding accuracy is required. Typical applications include surface grinders, cylindrical grinders, and CNC cutting tool machines. It performs best on soft carbon steels, tool steels, and super alloys where a medium-grade wheel provides the right balance of cut rate and finish quality. The white aluminum oxide construction and non-porous, vitrified bond deliver consistent performance across repeated dressing cycles, making it a reliable option for tool rooms and production grinding operations.

Key Features

• Vitrified bond construction for rigidity and reliable performance through repeated dress cycles
• 60 grit, medium grade, hardness code I for balanced stock removal and surface finish
• Non-porous, Type 1 flat wheel profile with no recess and no taper
• Rated to 3600 RPM maximum operating speed
• Compatible with surface grinders, cylindrical grinders, and CNC cutting tool machines

Compatibility

Designed for use with surface grinders, cylindrical grinders, and CNC cutting tool machines. Suitable for grinding soft carbon steels, tool steels, and super alloys. Fits machines with a 1-1/4 inch arbor hole.

Installation Notes

Grinding wheel installation and dressing should be performed by a qualified machinist or grinding technician. Before mounting, inspect the wheel for cracks or chips using the ring test per ANSI B11.9 guidelines. Power down and lock out the grinder before changing wheels. Never exceed the 3600 RPM maximum speed rating marked on the wheel.
