The Knipex Cobra Hightech Water Pump Pliers, No. 87 01 125, give users superior grip while not being hard to adjust in confined areas. The pliers’ gripping surface has special hardened teeth, with a tooth hardness of approximately 61HRC, allowing for low wear and stable gripping. The box-joint design offers high stability because of the double guide and the reliable catching thanks to its hinge bolt, which permits no unintentional shifting. The tool has a guard that prevents the user’s fingers from being pinched and it comes constructed of chrome vanadium electric steel.
