Diagonal pliers Knipex 77 42 130

Diagonal pliers Knipex 77 42 130 are precision cutting pliers designed for fine cutting work in electronics and fine mechanics. Made from high-grade special tool steel, forged and oil-hardened, these 130 mm pliers combine a pointed head and induction-hardened cutting edges to provide precise, durable performance with a cutting edge hardness of approximately 57–62 HRC.

Advantages

The robust, zero-backlash box joint ensures stable blade guidance while a low-friction double spring provides gentle and even opening for controlled operation. The polished or mirror-polished finish (finish 2) combined with a fine film of oil offers effective rust protection and prevents chrome peeling that could cause circuit faults. Cutting edges are additionally induction hardened for improved wear resistance.

Suitable for

• Fine cutting of wires and small components in electronics
• Precision work in fine mechanics and watchmaking
• Delicate cutting and trimming tasks in assembly and repair

How to use

Position the pointed jaws around the component or wire to be cut and apply steady pressure on the handles until the cut is complete. Use the pliers for precision and small-diameter conductors; avoid cutting hardened piano wire or materials beyond the specified capacity. After use, wipe the tool clean and store it dry to maintain the protective oil film and prevent corrosion.

Recommendations

For long-term performance, avoid exposure to corrosive environments and reapply a light film of oil after cleaning. Do not use the pliers for prying or as a hammer; use them only for cutting and gripping tasks within their intended fine-cutting application range.
