Hunter's new OCL430MD hub-mounted rotor lathe is the ideal solution for shops that service medium-duty trucks and commercial vehicles. The OCL430MD offers all of the speed and productivity features of Hunter's popular OCL400 brake lathe, but includes more robust lathe components to service larger truck rotors. With a reinforced cutting arm and rugged tool holders, the new lathe resurfaces rotors up to 17.5 inches in diameter and up to 3.5 inches in thickness. A 1.5-hp, 230 VAC motor provides the additional torque required for medium-duty truck service.
