Abstract

　ガンドリルとして、切削部位へ吐出されたクーラントを切屑と共に切屑排出溝へ集中して排出でき、切屑詰まりによる切削穴内周の傷付きや加工精度の低下を防止でき、回転負荷の軽減による切削効率の向上と長寿命化を図り得るものを提供する。 　工具シャンク１と切削ヘッド２の内部にクーラント供給路１０，２０を有し、工具シャンク１の基部側から切削ヘッド２先端にわたる外周面に１本の切屑排出溝３を備え、切削ヘッド２の先端面２ｃにクーラント供給孔２１ａ，２１ｂと切屑排出溝３２に連通する排出口２２ａ，２２ｂを有し、切削ヘッド２の外周面に切屑排出溝３上を橋架して全周にわたって連続する環状凸部４ａ…が形成されてなる。
