Gun drill machine – The reason why customers choose HI-TAK !

Proprietary gun drill machines (difference in machinery)

Our gun drill machines do not simply open deep holes. Our machines are designed with a focus on drilling precision. Through our experiences evaluating machinery designs to assess complex issues related to contracted machining, we continuously reevaluate our development and designs, including main axle, precision components (chip box, rotator mechanism, shock absorbers, etc.) towards creating the machinery capable of achieving optimal drilling.
