Norton 69936662098 Surface Grinding Wheel 60 Grit 7 in

Product Description

The NORTON 69936662098 is a Type 1 surface grinding wheel designed for precision stock removal on ferrous metals. Built with aluminum oxide abrasive and a vitrified bond, it delivers consistent cut rates and controlled wear across extended grinding sessions. The wheel measures 7 inches in diameter, 1/2 inch thick, with a 1-1/4 inch arbor hole. Rated at a maximum of 3,600 RPM and carrying a J hardness code with a medium grade, it is suited for both wet and dry operation. Licensed machinists, tool-and-die makers, and CNC operators are the primary installers and users of this wheel.

This grinding wheel is rated for use on hard carbon steels, soft carbon steels, and tool steels. It is compatible with surface grinders, cylindrical grinders, and CNC cutting tool machines. The ruby-colored aluminum oxide grain and vitrified bond provide a non-porous wheel structure that resists loading on these material types. The 48A60-JVBE specification designation identifies the exact abrasive blend, grit size, hardness, bond, and structure for sourcing and replacement reference.

Key Features

• Vitrified bond construction provides a rigid, non-porous wheel structure
• J hardness code, medium grade — resists glazing on harder steels
• Supports wet and dry grinding operation
• Maximum rated speed of 3,600 RPM
• Type 1 straight wheel profile with no recess and no taper

Compatibility

Rated for use with surface grinders, cylindrical grinders, and CNC cutting tool machines. Material applications include hard carbon steels, soft carbon steels, and tool steels.

Installation Notes

Grinding wheel mounting and dressing should be performed by a qualified machinist or tool-room technician following ANSI B7.1 safety standards. Always de-energize and lock out the grinder before mounting or removing a wheel. Inspect the wheel for cracks or chips before installation using the ring test, and never exceed the maximum RPM stamped on the wheel or listed in the product specifications. Ensure the arbor hole fits the spindle without forcing, and use proper flange hardware rated for the wheel size.
