1. A dieless crimping tool comprising:
a working head including:
a head frame having a nest, an opening permitting access to the nest, the nest being monolithically formed into the head frame and having a substantially flat base portion and a pair of substantially flat side walls extending from the base portion at an angle relative to the base portion, the nest is configured to receive a crimping member, the nest being accessible from the opening such that the crimping member can pass through the opening and be received in the nest;
a monolithically formed movable indentor having a body, a front face extending from the body, and an impact surface having a pair of walls extending from the front face so that the impact surface is spaced away from the front face, wherein a geometry of the indentor substantially aligns with a geometry of the nest such that when the indentor is in an impacting position, the base portion of the nest is configured to receive the impact surface of the indentor and the pair of walls of the impact surface align with the pair of side walls of the nest; and
a carriage positioned within the head frame and having a pair of spaced apart legs integrally formed into or secured to the indentor body, each leg having a track guide arm configured to be operatively coupled to a guide configured to guide movement of the carriage; and
a tool frame including a piston releasably coupled to the indentor to selectively move the carriage along the guide such that the indentor is movable between a home position and the impacting position.
