Grinding discs increase the temperature enough to permanently discolor the steel. Up to 10X faster cuts with a circular saw blade for maximum productivity and efficiency, resulting in up to 60 seconds faster cuts in both metals and stainless steels versus standard grinding discs Advanced Laser Cut Stabilizer Vents trap noise and vibration for maximum stability, keeping the blade cool for straight, accurate cuts FOXBC industrial circular saw blades feature precision teeth made from fine grain ceramic carbide, durability and precision under the toughest conditions to keep your saw cutting cleanly for the best results.
