2 inch drilling capacity
With a drilling capacity of 2 inches (50.8 mm), the DeHoff 20 Series is designed for higher torque drilling applications.
The DeHoff 20 Series 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.
The DeHoff Advantage:
Hardened and ground steel box ways with hand-scraped saddle, gibs, and straps provide long-term drilling accuracy and reliability.
Robust coolant system
High-pressure coolant system is suitable for either oil or water-soluble coolants up to 2,500 psi (172 bar) or 160 gpm (606 L/min).
PC-Based machine controls
Embedded PC-based control system features Microsoft Windows OS and a 12-inch (305 mm) color display.
Versatile workpiece handling
Custom fixturing and automated part loading options available.
