ABSTRACT:
The shaft (1) of the drilling tool has a support (3) fixed in a cylindrical blind hole (2) by means of a fixing screw (10). The support has a rear cylindrical portion (3a) and a forward half-cylindrical portion (3b). The forward portion has a replaceable cutting insert (4) fixed in it by means of a clamping screw (8). This is screwed into a first thread (9) of the support, and this thread extends perpendicularly to the seating (5) provided for the replaceable cutting insert. The support has a second thread (9) running parallel to the first thread and this locates the fixing screw which is screwed into the support from below passing through an oblong hole (11) in the shaft. The base (2a) of the blind hole is provided with an adjusting screw (12) which is arranged so as to be displaced from its axil. The adjusting screw has a cylindrical centring shoulder (14) which is a snug fit in a hole (16) provided in the shaft (1) and adjoining the centring shoulder is provided at its forward end with a cylindrical spigot (15), the diameter of which is smaller than that of the centring shoulder, and this is a snug fit in a recess (17) provided in the cylindrical portion (3a) of the support (3). (Main Figure: FIG. 1).
