ABSTRACT:
The present invention concerns a combination tool for providing a bore in a workpiece and for introducing a fastener, especially a self-threading screw, into said bore. Said combination tool comprises a cylindrical core one end of which is provided with a stub shaft meant to be connected to a drive means and the other end of which carries a mounting member for a drill. A sleeve surrounds said core and carries a tightening member for said screw. Said sleeve is axially displaceable along said core from a first end position in which said drill protrudes through and outside of said tightening member into a second end position in which the drill is completely retracted inside of same. In said first end position the sleeve is rotatable relative to said core, but in said second end position it is stationary thereto both with respect to rotation and to axial displacement.
