Cold saw blades are used to cut metal using a relatively slow rotational speed, usually less than 5000 surface feet per minute (SFM) (25 m/s), and a high chip load per tooth, usually between .001"–.003" (0.025–0.08 mm) per tooth. These blades are driven by a high power motor and high-torque gear reduction unit or an AC vector drive.
