Diagonal pliers Knipex 79 22 125 ESD

The Knipex 79 22 125 ESD diagonal pliers are precision cutters for ultra-fine work in electronics and fine mechanics. With a total length of 125 mm, a jaw length of approximately 10 mm and a jaw thickness of 6.5 mm, these pliers are designed for exact cutting of delicate electronic components in ESD-sensitive environments. The cutting edges are very precisely ground, induction hardened to approximately 64 HRC and are available with very small bevels for exact cuts; a version without bevel is available for flush cutting. The tool is forged from chrome vanadium ball-bearing steel and features dissipative, electrically discharging handles to reduce the risk of electrostatic discharge.

Advantages

The pliers combine very sharp, precisely ground cutting edges with induction hardening for long cutting life and consistent performance. They are approximately 20% lighter than conventional electronics pliers, which improves handling during fine work. A bolted joint with carefully manufactured joint surfaces ensures even, low-friction movement across the entire opening range, supported by a smooth-running double spring for gentle, even opening. Ergonomically optimised multi-component handles provide comfortable use in ESD-sensitive applications.

Suitable for

• Ultra-fine cutting tasks in electronics assembly and repair
• Fine mechanics work requiring precise wire and component cuts
• Use in ESD-sensitive environments and clean rooms
• Situations requiring lightweight, precise hand tools for repetitive tasks

Key specifications

How to use

Hold the pliers by the multi-component handles and position the cutting edges precisely at the point to be cut. Apply steady, controlled pressure to perform an exact cut on wires or small components. After cutting, allow the double spring to open the pliers gently; avoid applying sideways force to the blades. Use the pliers for their intended precision tasks and avoid cutting hardened wire unless specified by the manufacturer.

Usage recommendations

Use these diagonal pliers in ESD-protected areas and on grounded workstations. Keep the cutting edges clean and free of residues to maintain cutting performance; inspect and, if necessary, have the blades professionally re-sharpened or replaced when wear affects cutting quality.
