摘要： A rotary cutting tool that is composed of a tool shank with at least one chucking groove or chip flute and one exchangeable cutting insert. At the tip of the shank a recess for accommodating the cutting insert is provided. The tool shank, on its circumference, has a limb with a bearing surface that is inclined relative to the tool axis and that corresponds to a likewise inclined bearing surface on a wing of the cutting insert. The inclination of the bearing surfaces produces an axial force that retains the cutting insert on the tool shank. The abstract of the disclosure is submitted herewith as required by 37 C.F.R. §1.72(b). As stated in 37 C.F.R. §1.72(b): A brief abstract of the technical disclosure in the specification must commence on a separate sheet, preferably following the claims, under the heading “Abstract of the Disclosure.” The purpose of the abstract is to enable the Patent and Trademark Office and the public generally to determine quickly from a cursory inspection the nature and gist of the technical disclosure. The abstract shall not be used for interpreting the scope of the claims. Therefore, any statements made relating to the abstract are not intended to limit the claims in any manner and should not be interpreted as limiting the claims in any manner.
摘要翻译：一种旋转切削工具，其由具有至少一个夹紧槽或切屑槽的工具柄和一个可更换的切削刀片组成。在柄的尖端处设置有用于容纳切削刀片的凹部。工具柄在其圆周上具有带有相对于工具轴线倾斜的支承表面的肢体，并且其对应于在切削刀片的机翼上同样倾斜的支承表面。轴承表面的倾斜产生将切削刀片保持在工具柄上的轴向力。披露摘要根据37 C.F.R.的要求提交。 §1.72（b）。如37 C.F.R. §1.72（b）：说明书中的技术性披露的简要摘要必须在单独的表格上开始，最好是在权利要求之后，在“披露摘要”标题下。摘要的目的是使专利和商标办公室和公众一般从粗略检查中快速确定技术披露的性质和要点。摘要不得用于解释权利要求的范围。因此，与摘要有关的任何陈述不旨在以任何方式限制权利要求，也不应被解释为以任何方式限制权利要求。

摘要： There is now provided a twist drill and a method for producing a twist drill which method includes forming a flute of a twist drill. The drill has drill material and a tip portion with a cutting lip. The drill has a land structure and a flute to remove chip residue. The land structure has a flute wall and a cutting edge structure that is disposed longitudinally along the flute wall. The cutting edge structure has a first portion at the drill tip portion and a second portion disposed away from the drill tip portion. The flute wall extends further into the land structure at the second portion of the cutting edge structure than at the tip portion to provide a greater amount of drill material at the tip portion than at the second portion of the cutting edge structure. The flute wall extends further into the land structure at the second portion of the cutting edge structure than at the tip portion to provide a greater flute volume per length at the second portion of the cutting edge structure than at the drill tip portion. The method provides for forming a drill with a grinding tool to form different angular transitions of the cutting edge structure.

摘要： The invention relates to a drill bit (2), having main cutting edges (4a, 4b) which are connected together by a transversal cutting edge (6). An open surface (7) which extends into a flute (8) lies adjacent to each main cutting edge. The drill bit (2) is ground, in particular, during a continuous three-dimensional grinding process in such a way that the open surface (7) forms a continuous curved surface which follows a radius of curvature (R) running from the main cutting edge (4a) in the direction of the flute (8). The continuous grinding process, in comparison to a conventional two-stage process, produces an improved drill bit geometry which is devoid of ridges (16). The ridge-free configuration reduces the mechanical stress during drilling to a minimum.
摘要翻译：本发明涉及一种具有通过横向切割刃（6）连接在一起的主切削刃（4a，4b）的钻头（2）。延伸到凹槽（8）中的开放表面（7）邻近每个主切削刃。特别地，钻头（2）在连续的三维磨削过程中被研磨，使得开口表面（7）形成连续的曲面，该曲面遵循从主切削行进的曲率半径（R）边缘（4a）沿着凹槽（8）的方向。与传统的两级方法相比，连续研磨工艺产生了没有脊（16）的改进的钻头几何形状。无脊部结构将钻孔过程中的机械应力降至最低。

摘要： A twist drill or rotary cutting device, in particular a drill, comprising a tool head or cutting insert consisting of a hard cutting material and a tool shaft which clamps the tool head between two clamp extensions that project axially from said tool shaft in such a way that the tool head is interchangeable. In the fixed position, the interconnected clamping surfaces of the tool head and the clamping extensions of the tool shaft lie on the surface of a truncated cone shaped fixing peg running coaxially with the longitudinal axis of the tool shaft. The fixing peg tapers in the insertion direction, facing the chuck end of the tool shaft.
