Claims (5)
- 工具シャンクとその先端部に装着される切削ヘッドの内部に、両者を連通するクーラント供給路を有すると共に、該工具シャンクの基部側から切削ヘッド先端にわたる外周面に、直線状に長手方向に沿う1本の切屑排出溝を備え、
切削ヘッドは、先端面に、前記クーラント供給路に連通するクーラント供給孔と、前記切屑排出溝に連通する排出口とを有すると共に、外周面に、切屑排出溝上を橋架して全周にわたって連続する環状凸部が形成されてなることを特徴とするガンドリル。 - 前記環状凸部の複数本が平行配置してラビリンスシール部を形成してなる請求項1に記載のガンドリル。
- 切削ヘッドは、前記切屑排出溝が先端面に開放した主排出口に対し、径方向の略対向位置で先端面に開口した副排出口と、この副排出口からヘッド内部を通って切屑排出溝に至るバイパス流路孔と、径方向の略対向位置で先端面に開口した2つのクーラント吐出口とを備え、複数の切刃が前記主排出口と副排出口とに臨んで分配形成されると共に、前記環状凸部がバイパス流路孔の切屑排出溝への合流部よりもヘッド基端側に配置してなる請求項1又は2に記載のガンドリル。
- 工具シャンクの先端部に切削ヘッドの基端部が着脱自在に同軸状に連結されてなる請求項1〜3のいずれかに記載のガンドリル。
- 工具シャンクは、少なくとも切屑排出溝の形成部分が断面C状をなすシャンク本体の内側に、内部をクーラント供給路とするパイプ材が挿嵌され、該パイプ材の前端部が外周に設けた雄ねじを介してシャンク本体側に螺着されてなる請求項1〜4のいずれかに記載のガンドリル。
