本发明涉及一种具有套筒状基体（1）的自攻螺纹嵌件以及一种用于制造螺纹嵌件的方法。 主体（1）沿着纵向轴线（I）从第一端面（2）延伸到第二端面（3），并且具有在锥形区域（7）中减小的外径。 在基体（1）中具有通道开口（4），该通道开口设有封闭的内壁。 此外，基体（1）具有内螺纹（6）和外螺纹（7）。 在外螺纹（5）的锥形区域（7）中设置有至少一个切割槽（8），该切割槽由基体（1）中的凹槽限定，该凹槽基本上通过基体（1）与锥体 被限定，其具有圆锥底面（11），锥形圆锥面（12）和对称轴（II）。 对称轴（II）与锥形底面（11）的交点或者位于由第一端面（2）限定的平面内或者沿远离第二端面（3）的方向偏移。 切割角度（α）可以大于对称轴线（II）的倾斜角度（β）。

The invention relates to a self-tapping threaded insert with a sleeve-like basic body (1) and a method for producing a threaded insert. The base body (1) extending along a longitudinal axis (I) of a first end face (2) to a second end face (3) and has an outer diameter that decreases in a conical portion (7). In the base body (1) has a through opening (4) is provided with a closed inner wall. Next, the base body (1) has an internal thread (6) and an external thread (7). In the tapered portion (7) in the external screw thread (5) has a cutting groove (8) at least is provided which is defined by a recess in the base body (1) whose shape substantially by the sectional area of ​​the base body (1) having a cone-shaped body is defined, the a conical base surface (11), a tapered conical surface (12) and an axis of symmetry (II) has. The intersection of the axis of symmetry (II) with the conical base surface (11) lies either in the through the first end face (2) defined plane or is in the direction from the second end side (3) offset away. A cutting angle (α) may be greater than an inclination angle (β) of the axis of symmetry (II).
