Pince coupante diagonale Knipex 77 42 115

Diagonal pliers Knipex 77 42 115 are compact precision cutters designed for fine cutting work in electronics and fine mechanics. Made from high-grade special tool steel, forged and oil-hardened, they feature induction-hardened cutting edges and a pointed head without bevel. The 115 mm length and low weight make them suitable for tight spaces and detailed tasks.

Advantages

The pliers have a sturdy, zero-backlash box joint and a low-friction double spring for gentle and even opening. Cutting edges are induction hardened to approximately 62 HRC, while the pointed head has a cutting edge hardness of approximately 57 HRC. A polished or mirror-polished finish (finish 2) with a fine film of oil provides rust protection and prevents chrome flaking that could cause circuit faults.

Suitable for

• Fine cutting in electronics and fine mechanics
• Cutting wires and small components in tight spaces
• Precision work requiring minimal backlash and controlled opening

How to use

Hold the pliers by the insulated plastic handles and position the pointed cutting edges around the wire or component to be cut. Apply steady pressure to close the jaws and cut cleanly through the material. Use the low-friction double spring to open the pliers gently between cuts for precise, repeatable operation. For safety, keep fingers clear of the cutting edges and wear appropriate eye protection when cutting.

Recommendations

For long life and consistent performance, keep the cutting edges clean and free of debris, avoid cutting hardened materials beyond the tool’s intended use, and store the pliers dry. If the finish is mirror-polished (finish 2), the fine oil film will protect against corrosion; reapply a light oil film if needed after cleaning.
