Features and Benefits
Bench lathes are used for light- to medium-duty work and are mounted onto a workbench or stand. They are capable of machining larger work than hobby lathes with swings of 9" to 13".
Variable speed pulleys are driven by a V-shaped belt system and a variable speed assembly, which has an infinite speed range regulated by the turn of a dial.
Single-phase refers to one phase line (coil) that connects to and runs voltage through the motor. Single phase lines are not as efficient as three-phase motors.
