The lathe features a 3-1/9" bore spindle that is supported by 2 tapered and one ball bearing. The universal gearbox allows inch, metric, diametral, and module pitch threads without changing gears. The one-piece cast iron base allows heavier cuts by absorbing vibration. The machine also includes a convenient front removable chip tray for easy cleanup and an easy-to-use large foot brake. The chrome molybdenum headstock gears are hardened, ground and shaved for durabiity and long life. The five position automatic carriage stop provides excellent productivity.
