Norton 69014191906 Type 11V9 Diamond Grinding Wheel

Product Description

The NORTON 69014191906 is a Type 11V9 diamond grinding wheel designed for precision grinding of hard and superhard materials. It measures 3-3/4 inches in diameter with an overall thickness of 1-1/2 inches and accepts a 1-1/4 inch arbor hole. The wheel uses Armored Synthetic Diamond (ASD) abrasive bonded in a resinoid matrix at a concentration grade of 75, rated at 150 grit for a very fine finish. The face angle is set at 70 degrees with a 3/8 inch face width and a 1/16 inch superabrasive depth. This wheel is suitable for both wet and dry operation and is intended for use by tool grinders, machinists, and industrial maintenance technicians working with carbide, ceramic, or hardened tool steel.

This wheel is suited for tool room and production grinding applications where a very fine surface finish is required on cutting tools, carbide inserts, and similar hard materials. The Type 11V9 cup wheel geometry makes it a standard choice for grinding tool faces, rake angles, and relief profiles on end mills, drills, and lathe tooling. It is compatible with bench grinders and pedestal grinders equipped with the appropriate flanges and guards for the 3-3/4 inch diameter. Both wet coolant and dry operation setups are supported, though wet grinding is generally preferred to extend wheel life and reduce heat at the workpiece.

Installation Notes

Installation should be performed by a qualified machinist or tool grinder familiar with abrasive wheel safety. Always power down and lock out the grinder before mounting or removing any wheel. Inspect the wheel for cracks or damage before mounting and verify that the grinder spindle speed does not exceed the maximum rated speed marked on the wheel. Use the correct flanges and guards as required by ANSI B11 and applicable OSHA abrasive wheel standards.
