Combining zirconia alumina and premium aluminum oxide abrasives, the BlueFire ZA ZA Type 27/42 cutting wheel lasts two to three times longer than aluminum oxide wheels. To provide a high cut rate with minimal kerf loss, the wheel features ultra-thin side reinforcing. Perfect for making clean, slender cuts on 400 series stainless and both hard and soft carbon steels, the wheel offers a high-performance bond to ensure free cutting. The well-balanced design reduces vibrations, which makes the wheel easy to handle and puts less strain on the grinder.
