Built with NorZon Plus abrasive grain, this wheel delivers consistent cut rate and longer service life compared to standard aluminum oxide wheels. It measures 5 inches in diameter, 1/4 inch thick, and features a 7/8 inch arbor hole. Rated at 12,225 RPM, it is designed for use with 4-1/2 inch to 5 inch angle grinders. Licensed tradespeople and fabricators working with structural steel, pipe, and ferrous metals rely on this wheel for weld grinding, surface preparation, and edge work.

This wheel is suited for professional metalworking applications in fabrication shops, construction sites, pipeline work, and industrial maintenance. The Type 27 depressed center profile provides clearance for flat surface grinding and lets the operator maintain a low grinding angle for controlled material removal. Sold individually with a minimum order quantity of 25, making it practical for shop stocking or crew-level procurement. Best suited for grinding mild steel, structural steel, and other ferrous metals.
