摘要： There has been a demand for a drill capable of stably carrying out a cutting process even for a high-strength fiber composite material, such as a carbon fiber reinforced plastic (CFRP). A drill (1) according to an embodiment of the present invention includes a bar-shaped drill body (3), a major cutting edge (15) which is located at a front end of the drill body (3) and has a straight-line region (21) in a front view, a rake surface (9) located along the major cutting edge (15), and a chip discharge flute (7) being extended spirally around a rotation axis (X1) of the drill body (3) in a direction from the rake surface (9) toward a rear end of the drill body (3). The rake surface (9) has a flat region (27) located along the straight-line region (21).

摘要： Provided is a drill that achieves a shape of chips curled without a needle-like projection and accordingly shortened in overall length and that more smoothly discharges the chips to further improve a tool life. Since a cross section orthogonal to an axial center C of a drill 10 has a first convex curve CL1 corresponding to a convexly-curved cutting edge portion 12a and a first concave curve CL2 corresponding to a concavely-curved cutting edge portion 12b intersecting with each other at an intersection A, chips generated from a cutting edge 12 are curled and formed into a shape having no needle-like projection and accordingly relatively shortened in overall length and are smoothly discharged with enhanced discharge property and, therefore, the tool life of the drill 10 is further improved.

摘要： A drill (1) has at least one cutting edge (2). A projecting shape of a passing area of a ridgeline of the at least one cutting edge (2) when the at least one cutting edge (2) is rotated around a tool axis (Tax) forms a line-symmetric and discontinuous line along a parabola, two parabolas, an ellipse or two ellipses. The projecting shape is drawn on a projection plane parallel to the tool axis (Tax).

摘要翻译：本发明提供一种钻头，其实现了在没有针状突起的情况下卷曲的切屑形状并且因此总长度相应地缩短并且更平稳地排出切屑以进一步提高工具寿命。由于与钻头10的轴心C正交的截面具有与凸弯曲切削刃部12a对应的第一凸曲线CL1和与相互交叉的凹曲面切削刃部12b对应的第一凹曲线CL2 在交点A处，由切削刃12产生的切屑卷曲并形成为不具有针状突起的形状，因此总长度相对缩短，并且顺利地排出，具有增强的排出特性，因此钻头的工具寿命 10进一步改进。
