The proposed tool comprises sampling tube (11), and sampling unit (1) which is provided with handle and connecting element (12). Typically the sampling tube (11) can be used as a drill. Its end is ground to have an angle (alpha) of 20-70 degrees. Also, the edge of the tube is ground sharp. The other end of the sampling tube (11) is a regular polygon, preferably a hexagon, with an extension (12) through which n number of ribs (B1,B2,...Bn) form a clamping stem (122), which preferably extends to the 1st rib B1 and is fixed permanently. The handle and connection element (12) has a coupling stub (123), preferably of cylindrical shape, which extends from the nth rib (Bn) of the coupling stem (122). Inside it, there is a cavity, suitable for joining with the extrusion unit (2). Outside, there is provision for joining the wash-through syringe (2), preferably in the form of a LUERLOCK screw-thread. The discharge unit (2) is complete with discharge rod (2), fixing and discharge cap (22) fitted to the connection stub (123). The fixing extension (221) to be attached to the discharge rod (21). Preferably a half-spherical depression (223) is provided for permanently fixing the discharge rod (21) into the locating extension. |
