Abstract
A peck feed drill incorporates a motor gear quill and a feed control assembly together on a moving race track shaped piston. External construction of the housing permits mounting of an indexing adaptor plug for attachment of drill bushings. Internal construction of the housing provides for passage of air to the various components to which control tool operation. Valves within the air logic circuitry are multi-functional to minimize the number of parts.
