Abstract

258,692. Patterson, W. W., and Feet, T. E. July 3, 1925. Drills; taps.-An attachment to a drill for enabling countersinking or tapping to be performed comprises a sleeve 1, Fig. 1, having cutting teeth 3 and secured slidably but non-rotatably to the drill 2 by means of a screw 5 and two internal projections which enter the places of the drill. In a modification the cutting sleeve 10, Fig. 4, has a helical cutting edge and is formed in halves for ease in manufacture, one of the halves having a projection a, Fig. 9, for engaging a flute of the drill. A surrounding sleeve 11 and a screw 12 hold the cutter on the drill. Washers 8, 13, may be mounted above the cutting sleeves to vary the length of drill projecting from the lower end. In a further modification the cutting sleeve serves as a tap for the hole formed by the drill 2, the sleeve then being very thin and provided with an external screw-thread. Reference has been directed by the Comptroller to Specifications 25372/11, 26907/11, 109,102, 126,906, and 130,285.
