Norton 66252843788 Type 27 Grinding Wheel 6 in 24 Grit

Product Description

The NORTON 66252843788 is a Type 27 depressed center grinding wheel designed for aggressive material removal on angle grinders and right-angle grinding tools. The wheel measures 6 inches in diameter and 0.25 inches thick, with a 7/8-inch arbor hole. It uses a coarse 24-grit zirconia alumina abrasive bonded with a resinoid bond system, delivering fast stock removal on steel, stainless steel, and other ferrous metals. Licensed trades and fabricators rely on this wheel for weld grinding, surface prep, and edge cleanup in both shop and field applications. Maximum rated speed is 6,600 RPM.

This wheel fits standard 6-inch angle grinders with a 7/8-inch arbor. It is suited for heavy-duty grinding tasks in metal fabrication, structural steel work, shipbuilding, and maintenance welding. The Type 27 depressed-center profile provides clearance for flat and contoured surface grinding, making it practical for work in tight areas and along weld seams. The coarse 24-grit cut rate is appropriate for rapid stock removal rather than finishing passes.

Installation Notes

Installation should be performed by qualified personnel following ANSI B7.1 grinding wheel safety standards. Always inspect the wheel for cracks or damage before mounting, and never exceed the rated 6,600 RPM maximum speed. Ensure the grinder guard is in place before operation, and wear appropriate PPE including a face shield. Match the wheel arbor hole and diameter to the grinder spindle before mounting.
