| description | PROBLEM TO BE SOLVED: To provide a generic milling tool with which a pilot hole can be generated over its entire length at an unprecedented roundness.SOLUTION: There is provided an end mill including front cutting edges and circumferential cutting edges. One front cutting edge 24-1 passes over into a second front cutting edge 24-2 via a free surface intersecting line, and additional front cutting edges lying between the circumferential cutting edges in the cutting direction are offset relative to each other by a first angular pitch TW1 of 180°, and end before the middle. So that the end mill can be used in an especially advantageous manner for incorporating dimensionally and positionally precise pilot holes or chamfering, the first front cutting edge is offset relative to the second front cutting edge in the cutting direction by a second angular pitch TW2 ranging between 173° and 177°, preferably between 174° and 176°. The first front cutting edge is offset relative to the next additional front cutting edge in the cutting direction by a third angular pitch TW3 ranging between 90° and 94°, preferably between 91° and 93°.
【課題】パイロット穴を全長において今まで達成されていない真円度で開けることを可能にするための一般的なフライス工具【解決手段】１つの正面切れ刃２４−１は逃げ面交線を経由して第２正面２４−２切れ刃に移り変り、切削方向においてその間にある、互いに１８０?の第１分割角ＴＷ１ずれて配置されているさらなる正面切れ刃は中心部の前で終わる。形状および位置が正確であるパイロット穴あけまたは面取りにエンドミルをとりわけ有利に使い得るために、第１正面切れ刃は、第２正面切れ刃に対して切削方向に、１７３?から１７７?まで、好ましくは、１７４?から１７６?までの範囲にある第２分割角ＴＷ２でずれて配置されており、ここで、第１正面切れ刃は、切削方向に次のさらなる正面切れ刃に対して、９０?から９４?まで、好ましくは、９１?から９３?までの範囲にある第３分割角ＴＷ３でずれて配置されている。【選択図】図２ |
