Abstract: A crimping tool for crimping an electrical contact toward engagement with an electrical conductor, including a housing, a pair of crimping dies, a die support arrangement supporting a first one of the crimping dies in a stationary position on said housing, and a displacing mechanism for displacing the other crimping die between open and closed positions relative to the stationary crimping die. The displacing mechanism includes a rotary drive shaft, a crimping arm having a first end portion connected with the movable crimping die member, and a rotary-to-reciprocatory motion converting mechanism adjacent the other end of the crimping arm for transforming the rotary motion of the drive shaft to a reciprocatory motion of the crimping arm, thereby to displace the movable crimping die between the open and closed positions.

Abstract: A drill cutting attachment for severing an electrical conductor includes a housing, a stationary cutting blade connected with the housing, a movable cutting blade pivotally connected with the stationary cutting blade for displacement about a given cutting pivot axis between open and closed positions relative to the stationary cutting blade, and a pawl and ratchet arrangement for displacing the movable cutting blade from the open position toward the closed position, thereby to sever an electrical conductor positioned between the blades. The pawl and ratchet arrangement includes a transport pawl member that is longitudinally reciprocated by a rotary drive shaft via either an eccentric and crank arm drive arrangement, or a cam and follower drive arrangement. The drive shaft has a free end with a hexagonal cross-sectional configuration for connection with the chuck of an electric drill, and an attachment sleeve connects the housing with the electric drill body.
