Abstract

22,498. Barnes, J. W. Oct. 12. Drills; sockets. - The ends of twist drills are made cylindrical and with domed or rounded ends 5 which engage a coned seat in the socket 7 to centre the drill. Annular clearance is provided between the tool shank and the socket to allow the shank to float to aline itself with the hole being drilled. The drill is held by a chuck as described in Specifications 7262/11 and 3817/12, the dogs 11 being pressed into grooves in the shank by a sliding sleeve 12.
