Abstract

950,625. Drills. L. A. MORTENSEN. Dec. 5, 1960 [Nov. 1, 1960], No. 41789/60. Heading B3C. A drill for drilling tiles, concrete &c. comprises a shank 8, slotted at 10, a cutter 12 soldered in the slot, and a helical wire 20 for removal of cuttings, engaged in a hole 18 in the shank, and loosely surrounding the latter. The ends 16 of the shank are bent in opposite directions to allow cuttings to pass from the cutting edges to the lowermost part of the wire. The wire 20 may have a single winding, as shown, or a double winding may be provided, in which case the wire is soldered in slot 10, and a winding is produced by each end of the wire, and hole 18 is omitted.
