Norton 66252843791 Gemini Xxl Type 27 Grinding Wheel 7in

Product Description

The NORTON 66252843791 is a Type 27 depressed center grinding wheel designed for aggressive stock removal on ferrous metals. Built under the Gemini XXL product line, it measures 7 inches in diameter by 1/4 inches thick with a 5/8 inch to 11 inch arbor. The wheel uses a ceramic-coated premium aluminum oxide abrasive grain rated at extra coarse grit, paired with a high-performance bond that delivers a rapid cut rate and extended wheel life. It is suited for use with standard angle grinders and is a dependable choice for fabrication and weld work environments where throughput matters.

This grinding wheel is intended for use on 400 Series stainless steel, hard carbon steel, and soft carbon steel. Typical applications include flashing, beveling, smoothing, and weld bead removal in fabrication shops, field welding operations, and metal finishing environments. The depressed center profile provides clearance for the grinder body, making it practical for flush and recessed grinding in tight workspaces. It is commonly installed on right-angle grinders used by ironworkers, welders, pipefitters, and general fabricators.
