Norton 69014191849 Diamond Grinding Wheel 120 Grit 7in

Product Description

The NORTON 69014191849 is a Type 1A1 diamond surface grinding wheel designed for precision material removal in industrial and trade grinding applications. Built with synthetic diamond abrasive and a resinoid bond, this wheel delivers consistent stock removal on hard and difficult-to-grind materials. It measures 7 inches in diameter, 3/8 inches thick, and features a 1-1/4 inch arbor hole for secure mounting. The 120-grit fine grade is suited to controlled surface finishing and roughing operations where tight tolerances matter. Wet operation is specified, making it appropriate for coolant-assisted grinding setups. The wheel weighs 1.85 pounds.

This wheel is used in surface grinding operations on stationary surface grinders in machine shops, tool rooms, and production grinding environments. The Type 1A1 straight wheel profile fits standard surface grinder spindles with a 1-1/4 inch bore. The fine 120-grit rating positions it for finish-stage roughing and cut-off work on hard materials including carbide, ceramics, and hardened tool steels. It is part of the Norton Diamond series and carries a superabrasive concentration rating of 100 with a synthetic diamond (SD) abrasive depth of 1/4 inch. A licensed machinist or grinding technician typically handles setup and wheel changes on surface grinding equipment.

Compatibility

Designed for use on surface grinders accepting a Type 1A1 straight wheel with a 1-1/4 inch arbor bore, 7 inch diameter, and 3/8 inch width. Intended for wet grinding operation with compatible coolant systems.

Installation Notes

Wheel mounting must be performed by a qualified machinist or grinding technician following ANSI B7.1 safety standards for abrasive wheel use. Power down and lock out the grinder before inspecting, mounting, or removing any wheel. Conduct a ring test before installation and verify flange size, arbor fit, and rated wheel speed against the machine nameplate. Never exceed the maximum operating speed marked on the wheel.
