  Shoemaker's drill.



   The Schuhmachorbohror forming the subject of the present invention is shown in the drawing in Fig. 1 in view and in Fig. 2 in section.



   In the wooden handle, a sleeve a provided with a nut thread on the inside is fastened in any known manner. In this sleeve a lateral opening c is provided at the bottom of the bore, into which the lower part d of the drill f, bent at right angles, is inserted. To hold the drill in the sleeve a, a centrally drilled nut e is used, which is placed over the drill and screwed into the sleeve a with the aid of a wrench.



   With this arrangement, the drill is secured against rotation as a result of the lower part reaching into the opening of the sleeve a, and a broken drill can be replaced easily and quickly.
