236 ISCAR DEEP HOLE DRILLING %u00bd%u0009Ejector System DTSThe ejector drilling system was developed in the 1960s and was first shown at the EMTE exhibition in 1965. The technology of ejector drilling of deep holes involves the use of a tool with two stems (two pipes); therefore, it is also called the DTS (Double Tube System). Ejector drilling provides practically the same results in terms of productivity, accuracy, and hole quality as deep drilling with internal and external coolant supply. An ejector system allows drilling on existing machining centers, horizontal boring machines, lathes, or turning centers, etc., by adding a pumping coolant station. With ejector drilling, it is not required to seal the gaps between the workpiece and the tool system, which simplifies setup and maintenance of the machine.Ejector drilling systems can be used to drill holes in a wide variety of workpieces, including interrupted holes such as crankshafts, track shoe, and more.ISCAR provides DTS drills for drilling holes with an inner diameter of 18.4 mm to 184 mm and a depth of up to 325 drill diameters.
