Abstract

738,048. Hand drills. BRENNER MASCHINENUND WERKZEUGBAU GES., F May 6, 1953, No. 12646/53. Class 83 (3). A device for adapting a portable drilling machine 1 to drill large holes in masonry &c. comprises a carrier 6 connectible tc the machine by the clamping-jaws 11 of the machine handle 3, an internallytoothed ring 7 rotatable on a stationary pin 9 and on which a core drill 14 can be mounted, and a toothed wheel 5 on the machine spindle 4 driving the ring 7 at reduced speed. In a modification, the toothed ring 6, Fig. 5, is concentric with the machine spindle 4 and is driven by the gear 5 through pinions 26, 27 rotating on stationary axes. A drill, such as the centre drill 16, may be mounted in a socket 17 attached to the ring 7. Drills and cutters.-The annular masonry cutter 14 is inserted in an appropriate groove 12 of the ring 7 and locked by a bayonet coupling 13. The cutter has inserted blades 21 and is cut away to allow cuttings to escape.
