Combining a patented SG ceramic alumina with a NorZon zirconia alumina, the NorZon Plus SGZ CA Type 28 saucer wheel ensures a high cut rate at an affordable cost. This wheel offers outstanding durability and delivers a performance rate up to two to three times higher than competitors' high-performance zirconia or ceramic wheels. Use this wheel with a right angle grinder for stock removal, weld smoothing and beveling jobs on 400 series stainless, as well as hard or soft carbon steels.
