Claims

[Scope of Claim for Utility Model Registration] A substantially cylindrical cover covering the cutter body is disposed on the outer circumferential side of the cutter body having a cutting tip provided on the outer periphery of the tip, so as to be rotatable relative to the cutter body, A chip guide member is disposed at the tip of the cutter body and faces the rake face of the cutting blade tip with a gap, and the chip guide member is arranged to guide the chips generated along the rake face of the cutting blade tip. The chips are sucked into the chip storage chamber between the inner surface of the cover and the outer peripheral surface of the cutter body through the gap between the chip guide member and the rake surface of the cutting tip, and are then sucked through the discharge port provided on the cover. A milling tool with a chip suction mechanism configured to discharge chips, characterized in that the chip guide member is provided so as to be movable in the circumferential direction of the cutter body.
