摘要： A twist drill includes a cutting portion and a drill body. The cutting portion has a chisel edge, a segment relief surface, a chamfer relief surface and at least two flutes extending longitudinally to the drill body. Each flute has a rake surface and a gash extending away from the chisel edge. The cutting portion further has at least two cutting segments, each cutting segment having a first curved cutting edge, a second curved cutting edge and a chamfer cutting edge.

摘要： A cutting head has a resilient male coupling member. The cutting head has a central resilience slit that extends between two major surfaces and opens out to the male coupling member and at least one lateral resilience slit that extends between the two major surfaces and opens out to a base surface. The central resilience slit and the at least one lateral resilience slit each have forwardmost points, located forward of the base surface. Also, a cutting tool that has a tool holder with the cutting head secured thereto. The tool holder has an insert pocket that includes a forward facing holder base abutment surface that has a female coupling member. In a locked position, the male coupling member is resiliently retained in the female coupling member. All points on the male coupling member are under deflection.
摘要翻译：切割头具有弹性阳联接构件。切割头具有中心弹性狭缝，其在两个主表面之间延伸并且向外伸出到阳联接构件和至少一个横向弹性狭缝，其在两个主表面之间延伸并且向基部表面敞开。中心弹性狭缝和至少一个侧向弹性裂缝各自具有位于基部表面前方的最前面的点。此外，具有固定有切割头的刀架的切削工具。工具架具有插入口袋，其包括具有阴联接构件的向前保持器底座邻接表面。在锁定位置，阳联接构件弹性地保持在阴联接构件中。阳联接构件上的所有点都处于偏转状态。
