Knipex 87 Series Cobra Quickset Hightech Waterpump Pliers are made from high-grade vanadium special tool steel, that has been forged and then oil-hardened, for a longer, robust working life These pliers combine the proven, reliable locking of the hinge bolt with an additional push function which makes it easier to work in very confined and inaccessible areas. The adjustment directly on the workpiece is possible by simply sliding the pliers handle. For pipes, nuts, sleeves, for various kinds of components: slide the Knipex Cobra QuickSet open completely, place the upper jaw on the component and push the lower handle of the pliers up the component. The spring-loaded hinge bolt locks securely into place and can only be moved again by pressing the QuickSet button. Thanks to the 25-fold fine adjustment, the Cobra QuickSet can be ideally adjusted to different sizes of the component. This fine adjustment also makes sure that the distance to the handles remains hand-friendly for every opening width. The Cobra QuickSet is further stabilised by the box joint design. Unlike pliers with mounted joints, no tilting forces arise when under strain. The handles stabilise each other in the joint.
