Tronchese Knipex 78 91 125

Precision side-cutting pliers designed for ultra-fine cutting tasks in electronics and fine mechanics. The Knipex 78 91 125 features ground, very sharp cutting edges without bevel and precision-shaped tips that cut wires resting on a board from 0.2 mm diameter. The pliers include a stainless steel rivet joint, induction-hardened cutting edges, an opening spring and an opening limiter for controlled use. Available in INOX or special tool steel and supplied with a plastic handle for comfortable grip.

Advantages

The cutting edges are precision ground and induction hardened for long-lasting sharpness and a cutting edge hardness of approximately 64 HRC. A lead catcher prevents uncontrolled loss of cut wire ends. The joint with stainless steel rivet and extremely smooth movement reduce operator fatigue. The compact 125 mm length and lightweight construction provide good accessibility and handling for fine work.

Suitable for

• Ultra-fine cutting in electronics assembly and repair
• Fine mechanics and precision model work
• Cutting hard and soft wires from circuit boards (from 0.2 mm dia.)
• Soldering-preparation and cable trimming in tight spaces

Key specifications

• Overall length: 125 mm
• Weight: approx. 27 g
• Cutting edge hardness: approx. 64 HRC
• Cutting capacity (on board): from 0.2 mm diameter
• Material options: INOX or special tool steel
• Finish: burnished
• Features: induction-hardened cutting edges, lead catcher, opening spring, opening limiter

How to use

Hold the pliers by the insulated plastic handles and position the precision-shaped tips around the wire to be cut, ensuring the wire rests on the board if working on PCB-mounted leads. Squeeze the handles evenly to cut; the lead catcher will retain the cut wire end. Use the opening limiter and spring for controlled single-handed operation and to prevent over-opening.

Recommendations

For best results, use these pliers for straight, clean cuts on component leads and board-mounted wires. Avoid cutting hardened screws or nails. Clean and lightly lubricate the joint periodically and inspect cutting edges for wear; regrind only with suitable tooling to maintain edge geometry and hardness.
