Diagonal pliers Knipex 79 42 125

Diagonal pliers Knipex 79 42 125 are precision cutters designed for ultra-fine cutting tasks in electronics and fine mechanics. Forged from chrome vanadium ball-bearing steel and fitted with ergonomically optimised multi-component plastic handles, these 125 mm pliers combine durability with a comfortable grip. The pliers are approximately 20% lighter than conventional electronics pliers and feature a bolted joint with carefully manufactured joint surfaces for even, low-friction movement across the entire opening range.

Advantages

Very precisely ground, sharp cutting edges with very small bevels provide exact cutting on delicate electronic components; an option without bevel is available for flush cutting. The cutting edges are induction hardened to about 64 HRC for long-lasting sharpness. A smooth-running double spring ensures gentle and even opening, while the light weight and precise bolted joint improve handling in tight spaces.

Suitable for

• Ultra-fine cutting work in electronics
• Delicate tasks in fine mechanics and watchmaking
• Cutting small wires and component leads in circuit boards
• Applications requiring precise, low-deformation cuts

How to use

Hold the pliers by the multi-component handles and position the pointed head so the cutting edges contact the material close to the joint for maximum leverage and clean cuts. Apply steady pressure to close the blades; for flush cutting, use the bevel-free variant if available. After use, wipe the cutting edges clean and store the pliers in a dry place to avoid corrosion.

Recommendations

Use these diagonal pliers for precision trimming of component leads and fine wires; avoid cutting hardened wire or materials exceeding the pliers’ intended capacity to preserve the cutting edge and hardness.
