description PCT No. PCT/EP95/00841 Sec. 371 Date Dec. 26, 1996 Sec. 102(e) Date Dec. 26, 1996 PCT Filed Mar. 7, 1995 PCT Pub. No. WO95/25901 PCT Pub. Date Sep. 28, 1995The invention relates to a drill with a drilling shank, particularly with a screw shank comprising a self-tapping thread, and with a fork-shaped hard-material plate-shaped drilling tip disposed opposite the driving end of the shank, said drilling tip being inserted into a holder in the shank, said holder comprising two grooves, disposed diametrically with respect to each other in the shank, for accommodating prongs of the drilling tip. The shank terminates bluntly in an essentially radial end surface from which the grooves extend towards the driving end in such a manner that exclusively the prongs of the drilling tip, pressed axially into the grooves, both hold the drilling tip self-lockingly on the shank and also transmit the torque from the shank to the drilling tip.
