    1. Self-tapping threaded bush having an external thread (1), which comprises the pitch T, and having a cutting slot (3) extending in the axial direction and at right angles to the axis of the threaded bush, and a chamfer (11, 12) at the screw-in end of the threaded bush, which can be screwed into a smooth bore of a work piece, the thread profile of the cutting slot (3) cutting into an internal thread in the bore, characterised in that the beginning of the external thread (1) at the front surface (7) of the screw-in end substantially has a defined position in relation to the cutting slot (3) to obtain a defined cutting edge profile, regardless of the type of material of the work piece, in the bore of which the threaded bush is inserted.

    The invention relates to mechanical engineering. The aim of the invention is to increase the reliability of the connection. Figure 1 shows a self-tapping insert, a general view; 2 - cutting edge in the chamfer area | fig.Z - the same when turning 90; Fig. 4 shows a self-cutting insert with a concave face; Fig. 3 shows a self-bolt with an enlarging insert. The self-cutting insert includes a housing 1 with an internal 2 and an external 3 thread with a chamfer 4 at the lead-in part and a cutting slot 5. The cutting spitz is made with a depth greater than the height of the chamfer by an amount not exceeding the length of two steps of the external thread The bottom 6 of the cutting slot is inclined to the axis 7 self-tapping insert and is located between the depression 8 and the protrusion 9 of the external thread, while the bottom tilt angle is 0.5 step T of the external thread, and the slope coincides with its direction. . Chamfer 4, depending on the material in which the self-cutting insert is screwed, may have a shaped shape: concave (Fig. 4) for brittle materials and thick for soft materials. To obtain different screwing moments, the insert changes the position of the spitz relative to the external thread, which influences the pePP8 profile. i
    10 bite the edges. Figure 2 shows the slotting of the slot when the protrusion (ridge) 9 of the thread is located at the intersection of the end plane 10 and the plane 11 of the slot; in FIG. 3, when the protrusion is above the end plane by 1/4 of the thread pitch. Formula 1 and 3 above 1. Self-cutting insert, comprising a housing with internal and external threads with a chamfer on the lead-in part and a cutting spitz, characterized in that, in order to increase the reliability of the connection, the cutting slot is complete depth greater chamfer height by an amount not exceeding the length of the two steps of the external thread. 2. Insert pop. 1, characterized in that the bottom of the cutting slot is inclined to the axis of the self-cutting insert and is located between the hollow and the protrusion of the external thread. 3. The insert according to claim 2, characterized in that the angle of inclination of the bottom is 0.5 step of the external thread. 4. The insertion of claim 2, distinguished by the fact that the slope of the bottom coincides with the direction of the external thread.
