Abstract

615,263. Drills. LILLY, K.W. June 12, 1946, No. 17537. [Class 83 (iii)] A tubular drill for drilling bricks, tiles and the like has a pointed guiding attachment 6 slidably mounted in the end of the drill, the attachment having one or more projections 9 to engage the teeth 2 of the drill. The projections prevent continued drilling after a start has been made so that the attachment must be removed to enable drilling to be continued. The drill is plugged with a shank at one end in order that it may be held in a brace and holes are provided in the tubular wall to allow cuttings to escape.
