A crimp tool for creating a crimp connection between a coaxial cable having an inner conductor, an outer conductor, and a coaxial connector having an outer conductor part, employing an anvil to hold the outer conductor part, the anvil having a recess with an arcuate face of a first radius of curvature, and anvil arm points at each end of the arcuate face, and employing a die to apply the crimping force, the die having a recess with an arcuate face of a second radius of curvature, wherein said die recess extends over an internal angle of approximately 180°, terminating in two parallel arms, where a radial force is applied from outside on the outer conductor part over at least a part of the circumference of the outer conductor part, such that a cold weld is achieved.
