DeHoff 20 Series

High-torque gundrilling applications

With a drilling capacity of 2 inches (50.8 mm), the DeHoff 20 Series is designed for higher torque drilling applications. It uses a High-Torque Gearbox that enables the operator to change the spindle torque with the pull of a lever, instead of a time-consuming belt and pulley changeover. The 20 Series also features a larger ballscrew and higher torque servo, enabling it to deliver up to twice the torque of a standard duty machine.

Each 20 Series machine includes our robust coolant system and a Microsoft Windows®-based controls package. Various fixturing options and workpiece counter rotation are also available.
