The ejection hole 30 is formed so as to open toward the tip (circle P) of the flank 22b of the throw-away tip 22. Then, the ejection holes 26, 30 are connected to the supply port 34 formed on the lower surface side of the tool body 14 by the flow path 32 formed through the tool body 14. The supply port 34 is connected to a cooling liquid supply unit (not shown),
From here, the cooling liquid can be supplied toward the ejection holes 26, 30 at a predetermined pressure.
