Abstract

431,711. Drills and sockets. FERODO, Ltd., and MITTON, C., Sovereign Mills, Chapelen-le-Frith, Derbyshire. Jan. 20, 1934, No. 2095. [Class 83 (iii)] A drilling tool comprises a rotatable body portion, cross - slotted diametrically along part of its length and screw-threaded upon its outer surface, a screwthreaded collar and a bit having a flat shank the narrow sides of which are threaded and which is adapted to enter said cross-slot to any desired extent and to be secured therein by the screwed collar, the end face of the body portion from which the bit projects being formed as a stop or abutment to limit the depth of drilling. The flat cutting bit c with depth graduations h and threaded edges i is fitted into the slot e in the body portion d, Fig. 9, with the internally screwed sleeve b turned so that a pair of slots on its inner surface correspond with the slot in the body and allow free movement of the cutter in an axial direction. A part turn of the sleeve b then brings it against the collar a and locks the bit in position. The shoulder j of the body portion may have a facing surface or may be adapted for counter-sinking or counterboring.
