The present invention relates to a tool bar cooling device, and more particularly to an innovative structural type revealer for a tool bar cooling device that can alternately use different heat dissipating media.

According to the conventional cutting (drilling) processing machine, a cutter bar structure for holding a cutter is usually arranged at the working end of the machining spindle, and the combination between the conventional cutter bar and the cutter is usually a cone shape between the two. The structure is used for the purpose of guiding the clamping. However, in such a combination, when the axis of the arbor and the tool often cannot accurately correspond to each other linearly, it is not suitable for processing with high precision requirements.

Moreover, the appearance and size of the arbor produced by each arbor manufacturer are different, so the knives are cooled. There is also a problem that different brands cannot be applied between the machine and the arbor. Therefore, the conventional cooling jacket structure is indeed a bad design for a lot of money.
