workpiece.
Double Tube System (DTS)
Double tube system
The DTS is characterized by its two tube construction and is therefore known as the double tube system. A sealing system and pressure head, Double tube Workpiece Guide

suitable for conventional general purpose machines such as lathes or machining centers. In general, because of less efficient chip evacuation than the STS, the recommended max drilling depth
is 1000mm. The unique DTC-R tube connector that is capable of supplying high pressure coolant can, however, successfully achieve drilling depths of up No need for seal to 2000mm.
