The chuck is formed on a conical end portion of a cylindrical, rotatable element, and is capable of accurate alignment by economical manufacturing methods. The chuck also carries a cam surface for producing reciprocative motion to the drill bit. The rotatable element is mounted for pivotal motion about a horizontal axis and a second axis normal to the horizontal axis.
