An object of the present invention is to provide an implant hole forming drill that accurately drilled to a depth that was indeterminate the depth of the buried hole of artificial tooth root for the implant to be formed in the jawbone (fixture). A drill shaft portion 3 having a drill bit 3a provided on the end side, and a drill shaft body 2 the tool attachment shaft 4 is once provided on the distal side for attachment to a rotary driving tool, said drill shaft body a stopper mounting portion 5 provided in an intermediate portion of the second shaft line direction, and a cylindrical stopper member 7 mounted rotatably about the axis of the stopper mounting portion 5, the stopper mounting portion 5 is a tubular stopper member 7 is a configuration with implant hole forming drill to hold at a position which forms the depth of the artificial tooth root for purposes of buried. .BACKGROUND【課題】顎骨に形成するインプラント用の人工歯根(フィックスチャー)の埋設穴の深さを定まられた深さに正確に掘削するインプラント穴形成用ドリルを提供することである。【解決手段】端側にドリル刃3aを有するドリル軸部3が設けられ、かつ回転駆動工具に取り付けるための工具取付け軸4が末端側に設けたられたドリル軸本体2と、該ドリル軸本体2の軸線方向の中間部に設けられたストッパー取付け部5と、該ストッパー取付け部5の軸線回りに回転自在に取付けられた筒状ストッパー部材7とを備え、ストッパー取付け部5は筒状ストッパー部材7を目的の埋設用の人工歯根の深さを形成する位置で保持する構成としたインプラント穴形成用ドリルである。【選択図】図1
