Abstract

　切り屑の排出が円滑にでき高穿設性能のコアカッターを提供することを目的とし、当該コアカッターＣは、筒状の胴部１と、その先端で周方向に所定間隔に配設された複数の切刃２を有し、複数の切刃２のうちの少なくとも一つが内切刃２Ａとして、残りが外切刃２Ｂとして各機能するものであり、前記胴部１の厚みを耐変形性能が維持できる程度に薄く構成するとともに、先端に肉厚方向に貫通する貫通溝３を先端側に開口して設け、該貫通溝３内にその周方向の寸法に等しい寸法を有し前記胴部１と別体のチップからなる前記切刃２を挿着するとともに、前記切刃２の回転方向前方に、外周面が先端方にゆくに従って内周面に近づくような形態を備えた該外周面によって切り屑排出用のギャレット４を形成し、前記切刃２の前記貫通溝３への挿着を、切刃２の軸方向先端部の内径端が前記ギャレット４の軸方向先端部の周面と一致するか略一致するような状態で溶着でおこなった。
