Diagonal pliers Knipex 78 03 125 ESD

The Knipex 78 03 125 ESD diagonal pliers are precision cutting tools made of stainless steel with dissipative, electrically discharging handles. At 125 mm overall length and approximately 55 g weight, they are intended for ultra-fine cutting tasks in electronics and fine mechanics where ESD protection is required. The tool features very sharp, ground cutting edges without bevel for flush cutting and precision-shaped tips that can cut wires resting on a board from 0.2 mm diameter. The joint uses a stainless steel rivet and the pliers include an opening spring and an opening limiter for controlled operation.

Advantages

These ESD-safe diagonal pliers combine stainless steel construction with dissipative handles to reduce electrostatic risk. The ground, very sharp cutting edges allow flush cuts without leaving significant burrs, while the precision-shaped tips enable accurate cutting close to circuit boards. The stainless steel rivet joint and extremely smooth movement reduce operator fatigue. The built-in opening spring and opening limiter provide consistent, controllable action.

Suitable for

• Ultra-fine cutting in electronics assembly and repair
• Fine mechanical work requiring precise flush cuts
• ESD-sensitive environments and printed circuit board (PCB) work
• Hobbyist and professional tasks where compact, accurate cutters are needed

How to use

Use the pliers to cut component leads and small wires close to the board by positioning the precision-shaped tips at the desired cutting point and applying steady pressure until the wire is severed. For flush cuts, ensure the cutting edges meet cleanly against the workpiece surface. The opening spring returns the jaws after each cut; the opening limiter prevents overextension. Maintain a firm but comfortable grip on the dissipative handles to allow controlled cutting action.

Recommendations

Store and use the pliers in an ESD-protected area when working on electrostatic-sensitive components. Keep the cutting edges clean and avoid cutting hardened wire or materials beyond the specified application to preserve edge hardness (approx. 54 HRC). Regularly inspect the joint and cutting edges and replace the tool if chips or excessive wear appear.
