Diagonal pliers Knipex 79 22 120

Diagonal pliers Knipex 79 22 120 are precision cutting pliers designed for ultra-fine work in electronics and fine mechanics. Forged from chrome vanadium ball-bearing steel, they combine a compact 120 mm length with low weight and ergonomically optimised multi-component plastic handles for comfortable, accurate handling.

Advantages

Very precisely ground and sharp cutting edges with very small bevels provide exact cutting on delicate electronic components; a variant without bevel is available for flush cutting. The cutting edges are induction hardened to approximately 64 HRC for long-lasting sharpness. The pliers are around 20% lighter than conventional electronics pliers and feature a bolted joint with carefully manufactured joint surfaces for even, low-friction movement across the full opening range. A smooth-running double spring ensures gentle and consistent opening.

Suitable for

• Ultra-fine cutting work in electronics
• Precision tasks in fine mechanics
• Cutting wires, leads and small components

Key specifications

• Brand: Knipex
• Model / MPN: 79 22 120
• Length: 120 mm
• Weight: approx. 56 g
• Material: chrome vanadium ball-bearing steel

How to use

Hold the pliers by the multi-component handles with a light but firm grip. Position the cutting edges precisely on the wire or component to be cut, keeping the cut as close to the workpiece as required. Apply steady pressure until the cutting edges sever the material, then allow the double spring to reopen the pliers. For flush cutting, use the variant without bevel if available. Observe standard ESD precautions when working with sensitive electronic components.

Usage recommendations

Keep the cutting edges clean and free of residues; avoid cutting hardened wire or materials beyond the tool's intended use to preserve edge hardness and sharpness. Store the pliers dry and lubricate the bolted joint occasionally for long-term smooth operation.
