Le carottier (A) selon la présente invention comporte un corps de trépan cylindrique (1), des dents de coupe (2) disposées à l'extrémité inférieure du corps de trépan (1) et une tige (4) disposée à l'extrémité supérieure du corps de trépan (1) de façon à être maintenue par une foreuse. Le carottier est en outre pourvu d'un élément de compression déformable (6) disposé dans la partie creuse du carottier (1), faisant saillie radialement vers l'intérieur et pouvant subir une déformation radiale vers l'extérieur.
(JA)  穿孔完了後に前記切抜き廃材をコアドリル内部に確実に保留させて、下方への落下等を防止可能なコアドリルを提供することを目的とする。本発明にかかるコアドリルは、円筒状のコア体1と、該コア体1の下端に配設され切刃2と、前記コア体1の上端面に配設されドリリング装置側に取着するためのシャンク部4とを有するコアドリルAにおいて、前記コア体1の内周面に、該コア体の内径側に突出し且つ外径側に弾性を具備して変形可能に配設された押圧部材6を備えている。
