Norton 69014192313 Surface Grinding Wheel 12in 120 Grit

Product Description

The NORTON 69014192313 is a Type 1A1 diamond surface grinding wheel designed for precision surface grinding operations on hard and superhard materials. It measures 12 inches in diameter and 1 inch thick, with a 5-inch arbor hole. The wheel uses Armored Synthetic Diamond (ASD) abrasive at a 120 grit rating, classified as a fine grade. The resinoid bond holds the abrasive at a 75 concentration level with a 1/4-inch superabrasive depth. The hardness code is R, placing it in the soft wheel hardness range. This wheel is rated for both wet and dry operation and suits roughing and cut-off material applications. It conforms to specification ASD120-R75B99-1/4.

This wheel is used in surface grinding applications where tight tolerances and fine surface finishes are required on carbide, ceramic, glass, or other hard materials. It is well suited to precision machine shops, tool and die operations, and industrial grinding environments. The Type 1A1 straight wheel profile is compatible with standard surface grinder spindle setups. Wet operation is recommended when coolant systems are available to extend wheel life and control heat. Dry operation is permissible where coolant is not used.

Installation Notes

Surface grinding wheels must be installed by a qualified machine operator or maintenance technician familiar with abrasive wheel safety. Before mounting, inspect the wheel for cracks or chips using the ring test per ANSI B7.1 standards. Power down and lock out the grinder before changing wheels. Never exceed the maximum RPM rating marked on the wheel or machine spindle, whichever is lower.
