Claims

[Claims for Utility Model Registration] (1) In a milling tool in which a cutting tip is attached to the outer periphery of the tip of a tool body that is rotated about an axis, the tool body A first cover that covers the tool and opens toward the tool tip side is disposed in a rotatable state around the tool axis, and a first notch is provided at the tip of the first cover through which the cut portion of the workpiece material can pass. a second cover that opens toward the tool tip is fixed to a part of the outer periphery of the first cover, and a cut portion of the work material can pass through the tip of the second cover; , and when viewed in the feed direction of the workpiece,
A second notch is formed whose shape is substantially the same as the first notch, and the inner circumferential surface of the first cover and the tool body are formed in an area of the first cover that is not covered by the second cover. forming a first discharge port that communicates a first chip storage chamber defined between the outside of the first cover; a second portion defined between the outer circumferential surface of the cover;
A second discharge port is formed that communicates the chip storage chamber with the outside of the second cover, and the second discharge port is formed at the tip of the tool body so as to face the rake surface of the cutting blade tip with a gap therebetween. A milling tool characterized by being provided with a chip guide member that narrows an opening on the tool tip side of the cover. (2) The milling tool according to claim 1, wherein the first cover is equipped with a soft shielding material that shields the first notch. (3) The milling tool according to claim 1, wherein the second cover is equipped with a soft shielding material that shields the second notch. (4) A soft shielding material that shields the first notch is attached to the first cover, and a soft shielding material that shields the second notch is attached to the second cover. The milling tool according to claim 1, characterized in that:
