Description
先ネジを有しない木工用ドリル以外のドリルにおいては、ドリル本体が被切削材に引き込まれることはないが、穿孔深さを正確に一定とすることが必ずしも容易ではない。
上記構成とすることによって、一定深さの穿孔をしたときにストッパー本体3の先端が被切削材の表面に当接し、ドリル本体1の被切削材A方向への進行を防止し、正確に一定深さの穿孔をすることができる。このとき、ドリル本体1は被切削材Aの表面に当接して停止し、回転筒はドリル本体1とともに回転している。
図1は本発明に係るドリル用ストッパーを装着した木工用ドリル全体の正面図、図2はドリル用ストッパーのみの斜視図である。図3はドリル用ストッパーのみの断面図、図4はドリル用ストッパーの回転筒の断面図、図5はドリル用ストッパーのストッパー本体の断面図、図6はドリル用ストッパーを装着した木工用ドリルであって、穿孔の使用状態を示す一部縦断の正面図である。
以上述べた実施形態では、本発明に係るドリル用ストッパーを木工用ドリルに装着して使用する状態を説明したが、木工用ドリル以外のドリルに装着して、一定深さの孔を加工する場合に広く使用することができるものである。
Claims (1)
- ドリル本体に嵌挿しロック手段によってドリル本体に固定する回転筒と、該回転筒に対して中心位置で回転自在に装着されるカップ状のストッパー本体とで構成し、ドリル本体の先端がストッパー本体の先方に突出する状態で、回転筒をドリル本体に固定することによって一定深さの穿孔をしたときにストッパー本体の先端が被切削材の表面に当接してドリル本体の進行を防止するとともに、カップ状のストッパー本体の対向する二箇所の外周面に、軸方向に連続する面取りを施し、該面取り部分の周壁の一部を切除することによって窓孔を形成したことを特徴とするドリル用ストッパー。
