The Double Tube System (DTS) - The double tube system involves a boring bar or drill tube which is threaded to a drilling tool. Inside of this outer drill tube is an inner tube which creates a void between the O.D. of the inner tube and I.D. of the outer drill tube. Pressurized coolant is then forced through the void where a portion of the coolant is allowed to exit through slots in the inner tube while the majority of the coolant is directed to the tools cutting edge. These two coolant flows create a vacuum in the inner tube that exhausts the chips through the I.D. of the inner tube. The double tube system can be adapted to standard milling and turning machine tools. The addition of a high volume coolant system is needed for proper chip evacuation.
