- 穿孔するための打撃ドリルビットであって、
打撃ユニットに連結するために後端部に連結部分を有すると共に当該ドリルビットの回転軸線(CL1)を画定するドリルボディと、該ドリルボディの前端部内に埋め込まれる再研磨可能な複数の超硬ボタン(7、9、10)とを具備し、上記前端部は連結部分に対して固定されており、各ボタンは上記ドリルボディに埋め込まれた後方取付部分(20)を有する超硬ボディを具備し、その前端(18)はドリルボディから突出しており、上記超硬ボタンの前端はほぼ半球状に湾曲していると共に半径(R2)によって画定され、該半径(R2)の原点(C)は実質的に縁部(22)を含む平面(P)の軸線方向後方に配置され、上記前端は上記縁部(22)から開始する表面(18A)を有するドリルビットにおいて、
上記ボタン(7、9、10)は該ボタンの直径(D)の50%以上である距離(L2)だけ上記ドリルビットボディから突出し、上記表面(18A)と上記縁部(22)との間の円錐中間表面(21)は断面において上記後方取付部分(20)の包囲表面(25)に対して約13°〜19°の鋭角(α)を成すことを特徴とする打撃ドリルビット。 - 上記距離(L2)は上記ボタンの直径(D)の52%以上である請求項1のドリルビット。
- 上記超硬ボタンの湾曲した前方端部(18)は、円錐表面(22)に連絡し、次に上記ボタンの最大の直径(D)を画定する平面(P)を含む位置において上記ボタン(7、9、10)の包囲表面(25)に連絡する請求項2に記載のドリルビット。
- 上記半径(R2)は上記後方取付部分(20)の半径(R1)の約85%〜115%である請求項1に記載のドリルビット。
- ドリルボディに埋め込まれる後方取付部分(20)と、前記ドリルボディから突出する前端(18)とを有する、打撃岩盤ドリルビット用の再研磨可能な超硬ボタンであって、
当該超硬ボタンの前端(18)はほぼ半球状に湾曲し且つ半径(R2)により画定され、該半径(R2)の原点(C)は実質的に縁部(22)を含む平面(P)の軸線方向後方に配置され、上記前端は上記縁部(22)から開始する表面(18A)を有する再研磨可能なボタンにおいて、
当該ボタンは該ボタンの直径(D)の50%以上の距離(L2)だけドリルビットボディから突出するのに適しており、上記表面(18A)と上記縁部(22)との間の円錐中間表面(21)が断面において上記後方取付部分(20)の包囲表面(25)に対して約13°〜19°の鋭角を成すことを特徴とする再研磨可能なボタン。 - 上記距離(L2)は上記ボタンの直径(D)の52%以上である請求項5に記載の再研磨可能なボタン。
- 当該超硬ボタンの湾曲した前方端部(18)は、円錐表面(22)に連結し、次に上記ボタンの最大の直径(D)を画定する平面(P)を含む位置において上記ボタン(7、9、10)の包囲表面(25)に連絡する請求項6に記載の再研磨可能なボタン。
- 上記半径(R2)は上記後方取付部分(20)の半径(R1)の約85%〜115%である請求項5に記載の再研磨可能なボタン。
