摘要： In a semi-finishing cutter, rectangular tips and square tips are disposed in a staggered pattern in an axial direction in second to fourth step portions, so a single cutting edge is formed by a pair of one of the rectangular tips and one of the square tips. It is therefore possible to effectively reduce a frequency of contact with a blade root. A cutting speed of the semi-finishing cutter may be increased and a cutting feed may be made faster, so work in a semi-finishing process may be performed efficiently. The rectangular tips and the square tips have simple shapes, so known commercially available throwaway tips may be used. Accordingly, it is possible to provide the semi-finishing cutter in an easy-to-use form without increasing the cost.
摘要翻译：在半精加工刀具中，矩形尖端和方形尖端在第二至第四台阶部沿轴向布置成交错图案，因此单个切割刃由一对矩形尖端和正方形之一形成提示。因此，可以有效地降低与叶片根部的接触频率。可以提高半精加工刀具的切削速度，并且可以使切削进给更快，因此可以有效地进行半精加工工序。矩形尖端和方形尖端具有简单的形状，因此可以使用公知的市售的一次性顶端。因此，可以在不增加成本的情况下以易于使用的形式提供半精加工刀具。

摘要： In a rough cutting cutter, square tips and rectangular tips are disposed in a staggered pattern in an axial direction in second to fourth step portions, so a cutting edge is formed by a pair of one of the square tips and one of the rectangular tips. It is therefore possible to effectively reduce a frequency of contact with a blade root. Furthermore, in the second to a fifth step portions, ARs (rake angles in the axial direction) and RRs (rake angles in a radial direction) of the square tips and the rectangular tips gradually increase in order from a tip end to a back end of a tool body. It is therefore possible to suppress chatter vibration during machining and is possible to reduce roughness of a cut surface of a work material.
摘要翻译：在粗切割机中，方形尖端和矩形尖端在第二至第四台阶部沿轴向以交错图案设置，因此切割边缘由一对方尖端和一个矩形尖端形成。因此，可以有效地降低与叶片根部的接触频率。此外，在第二至第五阶段部分中，正方形尖端和矩形尖端的AR（轴向的前角）和RR（径向的前角）从尖端到后端的顺序逐渐增加的工具体。因此，能够抑制机械加工时的颤动振动，能够降低作业材料的切断面的粗糙度。

摘要： In FIG. 2, a diameter Dd of drilling edges of a drill is selected smaller than a valley diameter d1 of a male thread of a tap portion, and an inner diameter D1 of a female thread is defined by the valley diameter d1 of the male thread. Therefore, a predetermined radial gap is formed between the male thread 30 formed by the tap portion and the drill. When a tap with the drill is reversely rotated to be pulled out from the female thread after cutting the female thread, the tap released from the restriction may deflectively displace in the diameter direction upon pulling out the male thread of the tap portion from the female thread. However, the drill hardly contacts with the female thread, so that the occurrence of the defective product due to the contact is suppressed.

摘要： A shrink-fit tool unit increases the transmission force of rotary power and also improves workability when inserting the rotary tool into the tool holder. A tool holder and a rotary tool to be used for the shrink-fit tool unit are also disclosed. Since a first engaging part and a second engaging part are configured to engage with each other simply by inserting a cylindrical terminal area of a rotary tool, typically, a thread forming tap, into a chuck of the tool holder, even when the machining load receiving from a work piece act both in forward and reverse directions relative to the circumferential direction, it is possible to increase the transmission of rotary power.

摘要： A helical flute has a constant lead part and a gradually increased lead part. The constant lead part has an axial length ranging from 0.3×LA to 1.2×LA and includes at least entirety of a leading part, so that the cutting performance of a cutting edge at the leading part and shape of chips (curled shape, etc.) are stable. In the constant lead part, because a lead is the smallest and a helix angle is large, a rake angle of the cutting edge is large, so that an excellent cutting quality is obtained and the chips become curled well. Meanwhile, in the gradually increased lead part, because of the lead gradually increased toward a shank, the chips are rapidly discharged toward the shank.
摘要翻译：螺旋槽具有恒定的引导部分和逐渐增加的引线部分。恒定引线部分具有从0.3×LA到1.2×LA的轴向长度，并且包括至少整个前端部分，使得切屑的前端部分和切屑形状（卷曲形状等）的切割性能）是稳定的。在恒定引线部分中，由于引线最小，螺旋角大，所以切削刃的前角大，因此切削质量优异，切屑变得卷曲良好。同时，在引导部分逐渐增加的情况下，由于引线朝向柄方向逐渐增加，芯片迅速向柄方向排出。
