The X1 On-Truck Brake Lathe from Pro-Cut International features a low-range gearbox that provides 30 percent more torque than the company's standard car lathes and is powered by a 48V DC variable speed motor that can handle bus and truck axles. It is mounted on a four-wheel, four-axis adjustable trolley with a working range of 18" to 34". The X1 comes with three adapters, adjustable tool arms, and a 190mm feed screw that allows users to match-machine even extra-large rotors. It includes a 2-year parts and labor warranty.
