Title: Combination drilling and skiving tool

Patent Application ·
OSTI ID:5466011

This invention pertains to a combination drilling and skiving tool including a longitudinally extending hollow skiving sleeve slidably and concentrically mounted on right-handed twist drill. Dogs or pawls provided on the internal periphery of the skiving sleeve engage with the helical grooves of the drill. During a clockwise rotation of the tool, the drill moves downwardly and the sleeve translates upwardly, so that the drill performs a drilling operation on a workpiece. On the other hand, the drill moves upwardly and the sleeve translates downwardly, when the tool is rotated in a counter-clockwise direction, and the sleeve performs a skiving operation. The drilling and skiving operations are separate, independent and exclusive of each other. 5 figs.
