Claims

[Claim for Utility Model Registration] A concave groove that opens to the tip and outer circumference of the tool body is formed on the outer periphery of the tip of the cutter body that is rotated about the axis, and the cutting tip is inserted into the groove into the clamp member. Therefore, in the milling tool which is detachably attached to the cutter body, a substantially cylindrical cover which covers the cutter body and whose tip is open toward the tip side of the cutter body is provided on the outer peripheral surface of the cutter body. a suction port which is arranged to be rotatable relative to the main body, a chip storage chamber is formed between the inner peripheral surface of the cover and the outer peripheral surface of the cutter main body, and the suction port communicates with the chip storage chamber in the cover; forming a distal end opening of the concave groove at the distal end of the clamp member facing the distal end side of the tool body, between the rake face of the cutting edge tip and the inner circumferential surface of the distal end of the cover. A milling tool characterized by being provided with a chip guide portion that covers each part while leaving a gap therebetween.
