Types of Crimping Pliers


Hand Crimping Pliers

Hand crimping pliers are similar to combination pliers. The jaws feature a series of special profiles designed to squash (deform) the crimp connectors in the best way for secure wire connection.

The drawback with these types of pliers is that the pressure applied to deform the crimp is directly related to the strength of the person squeezing the pliers together – this could lead to insecure joints which can be a major fire hazard.

When many crimps need attaching, there would be inconsistent results and the last crimp may not be as secure as the first due to user fatigue.

For repetitive work, consistency is very important, this is where ratchet crimping pliers are ideal.
