Diagonal pliers Knipex 77 12 115 ESD

The Knipex 77 12 115 ESD diagonal pliers are precision cutters designed for fine cutting work in electronics and delicate mechanical tasks. At 115 mm overall length and weighing approximately 80 g, these pliers combine a forged, oil-hardened special tool steel construction with a mirror-polished finish and induction-hardened cutting edges for reliable, long-lasting performance in ESD-sensitive environments.

Advantages

Electrically dissipative handles reduce electrostatic charge build-up, making the tool suitable for ESD-protected areas. The sturdy, zero-backlash box joint and low-friction double spring provide gentle and even opening action. Mirror polish with a fine oil film offers effective corrosion protection without risk of chrome flaking that could cause circuit faults. Cutting edges are induction hardened to approximately 62 HRC for sustained sharpness. The two-colour dual-component grips (black/grey) ensure a secure and comfortable hold.

Suitable for

• Fine cutting work in electronics and circuit board assembly
• Precision tasks in fine mechanics
• Work in ESD-protected areas
• Cutting thin wires and leads with controlled results

Key specifications

• Model: 77 12 115 ESD

How to use

Position the diagonal pliers so the wire is aligned close to the cutting edge for a precise cut. Apply steady pressure on the handles until the cutting edges meet and sever the material. For best results with fine wires and leads, make a single clean cut rather than multiple partial cuts. Use the bevel and round head design to capture cut wire ends and prevent uncontrolled loss of cut pieces.

Recommendations

Use these pliers in ESD-safe workstations and avoid contact with corrosive chemicals; keep the mirror-polished surfaces lightly oiled for long-term rust protection. Do not use the pliers on hardened wire or materials beyond their rated cutting capacity to prevent damage to the cutting edges.
