The Cobra 87 03 125

The Knipex Cobra 87 03 125 is a 5-inch adjustable plier designed for precision mechanics, hobby tasks and home use. Its push-button adjustment lets you set the jaw directly on the workpiece without trial and error. A built-in pinch guard stops fingers from being caught during operation. The box-joint design adds stability through a double guide.

Button adjustment versus slip-joint

Traditional slip-joint pliers require multiple attempts to find the right opening. The Cobra replaces that process with a single button press and fine adjustment for optimum handle width. Self-locking jaws grip pipes and nuts without slipping, so less hand force is needed. The hinge bolt catches reliably to prevent unintentional shifting while you work.

Users needing one-hand sizing in tight spots

This tool suits anyone who values fast, one-hand adjustment in confined spaces or an emergency kit. Hardened teeth at approximately 61 HRC resist wear during repetitive gripping. Buyers who need larger capacity or insulated handles for electrical work should look at other models. The chrome-plated chrome vanadium steel construction resists corrosion in general use.

Questions about this item

What is the overall length of the 87 03 125 Cobra pliers?

The pliers measure 125 mm in total length, making them compact enough for tight spaces and emergency tool kits.

How do you adjust the jaw on the 87 03 125 Cobra pliers, and what step do people often miss?

Position the upper jaw on the workpiece, press the push button, then close the lower jaw; the common mistake is trying to pre-set the jaw width before placing it on the workpiece.

When will the gripping teeth on the 87 03 125 Cobra pliers need replacement?

The teeth are hardened to approximately 61 HRC for low wear; under normal use they last the life of the tool and are not designed to be replaced separately.
