With a patented Norton® SG blend of ceramic alumina and zirconia alumina grain, this NorZon Plus® 5SGZ CA Type 01/41 small diameter cut-off wheel is the fastest on the market, offering 10 times the speed of aluminum oxide cut-off wheels on 400 series stainless and both hard and soft carbon steels. The ultra-thin side reinforcement minimizes kerf loss while maximizing the cut rate and offering a precise cut on many materials. The performance-to-price ratio reduces the overall cost of grinding, and the high-quality resin promotes a long lifespan while allowing for a freer cut.
