Abstract
A tapping collet is actuated by engagement with a mating surface of a collet holder for holding a tap having a round shank portion and a square shank portion. The collet has a plurality of independent gripping jaws circumferentially disposed at essentially 90 degree intervals about a centerline axis through the collet. The gripping jaws have an inner face parallel to the centerline axis and an outer face which defines an outer surface for engaging a collet holder mating surface. Resilient material is disposed between the gripping jaws for holding the jaws in the desired spaced relation. The gripping jaws comprise a step portion which extends radially inward and defines a second inner diameter opening to engage the flat sides of the square shank portion of a tap inserted into the collet. The continuous outer diameter seal is disposed circumferentially about the outer surface of the collet and a continuous inner diameter seal is disposed circumferentially within a first inner diameter opening of the collet.
