Norton 66252843216 Type 27 Grinding Wheel 5 in 30 Grit

Product Description

The NORTON 66252843216 is a Type 27 depressed center grinding wheel designed for aggressive material removal on angle grinders. Built with a zirconia alumina abrasive in a coarse 30-grit grade, it delivers fast stock removal on steel, stainless steel, and other ferrous metals. The resinoid bond holds abrasive grains firmly during high-stress grinding passes, and the wheel is rated to a maximum of 12,225 RPM. At 5 inches in diameter and 1/8 inch thick, it fits standard angle grinders with a 7/8-inch arbor. Licensed tradespeople performing metal fabrication, weld grinding, and surface prep will find this wheel suited to demanding production and job-site work.

This wheel is intended for use on angle grinders in metal fabrication shops, welding operations, and industrial job sites. The Type 27 depressed-center profile allows flat and surface grinding applications where a raised hub improves clearance and control. It is appropriate for both residential and light commercial metalwork as well as heavier industrial grinding tasks. The coarse 30-grit rating makes it best suited for rapid material removal rather than finishing or blending operations.

Installation Notes

Installation should be performed by a qualified operator familiar with abrasive wheel safety per ANSI B7.1 standards. Always inspect the wheel for cracks or damage before mounting, and never exceed the marked maximum RPM. Ensure the grinder is unplugged or its power source is locked out before changing wheels. Use the correct flanges and never force the wheel onto the spindle.
