The Fast Cut Bi-Metal Hole Saws contain an extra cobalt HSS tooth material for enhanced heat and wear resistance, along with a new 5.5 TPI positive rake tooth design, to ensure a smoother and faster cut when compared against our previous Constant Pitch Hole Saw. Specifically designed to cut stainless steel, metals and mild steel sheet, the Fast Cut Saws will also cut through wood, plastic, plaster and other materials. The 5.5 TPI positive rake tooth form provides less torque for a smoother, faster cut in all materials.
