Diagonal pliers Knipex 77 22 115 ESD

The Knipex 77 22 115 ESD diagonal pliers are precision cutters designed for fine cutting tasks in electronics and fine mechanics. They are forged from high-grade special tool steel, oil-hardened and finished with a mirror polish and a fine film of oil to provide effective rust protection without peeling chrome. The tool features a sturdy, zero-backlash box joint and cutting edges that are induction hardened to approximately 62 HRC. The pliers have two-colour dual-component black/grey ESD-dissipative handles and a round head without bevel.

Advantages

The pliers combine precise cutting performance with durability: induction-hardened cutting edges (~62 HRC) maintain sharpness, while the mirror polish plus oil film prevents corrosion without causing circuit faults from peeling plating. The zero-backlash box joint and low-friction double spring ensure smooth, even opening. ESD-dissipative handles reduce electrostatic discharge risk in sensitive environments.

Suitable for

• Fine cutting work in electronics
• Delicate tasks in fine mechanics
• Use in ESD-sensitive workplaces
• Precision trimming of small wires and components

Key specifications

• Model: 77 22 115 ESD, round head, without bevel
• Length: 115 mm
• Weight: 80 g
• Material: High-grade special tool steel, forged, oil-hardened
• Cutting edge hardness: approx. 62 HRC (induction hardened)
• Handles: Two-colour dual-component, black/grey, dissipative (ESD)
• Joint: Sturdy box joint with zero backlash

How to use

Position the cutting edges around the workpiece close to the joint for clean, precise cuts. Use short, controlled pressure when cutting small wires or components to avoid deformation. After cutting, allow the pliers to open and close freely; the low-friction double spring provides gentle, even opening action. Store the tool in a dry place to maintain the protective oil film.

Usage recommendations

For ESD-sensitive work, ensure the user follows workplace ESD protocols and uses grounding measures as required. Regularly inspect cutting edges for wear and keep the tool clean and lightly oiled to preserve rust protection and cutting performance.
