Diagonal pliers Knipex 77 02 115 — steel, plastic handles, 115 mm

The Knipex 77 02 115 diagonal pliers are a compact cutting tool 115 mm in length, made from high-grade forged steel with plastic handles. Designed for precision cutting of soft and hard wire, cable ties and small components, this 80 g tool is intended for electronics work, fine mechanics, electrical installation and general repair. Induction-hardened cutting edges and corrosion-resistant finishes provide durability and reliable performance in both workshop and field environments.

Advantages

The pliers offer precision cutting edges with a hardness of approximately 60–62 HRC, ensuring clean cuts and long life. A sturdy, zero-backlash box joint and load-optimised geometry deliver a direct working feel, while a low-friction double spring ensures gentle and even opening. A polished or mirror-polished finish combined with a fine oil film provides effective rust protection without risk of chrome flaking that could cause circuit faults. Narrow handle sleeves extend to the head for secure guidance between thumb and index finger.

Suitable for

• Cutting soft and hard wires in electronics and fine mechanics
• Trimming cable ties and small plastic components during installations
• Precision work in electrical installation and maintenance
• General repair tasks requiring a compact, precise cutter

How to use

Hold the pliers by the plastic handles with the cutting edges aligned to the material to be cut. Position the wire or component close to the head for the cleanest cut and apply steady pressure until the cut is complete. Use the low-friction double spring to open the tool between cuts; do not force the jaws beyond their intended capacity. After cutting, wipe off residues and keep the cutting edges free from debris to maintain precision.

Usage recommendations

Use the Knipex 77 02 115 for fine cutting tasks within its capacity—avoid cutting hardened steel beyond the rated hardness of the cutting edges. Regularly clean and lightly oil the pivot and cutting surfaces to preserve the corrosion-resistant finish and cutting performance. Store the pliers dry and inspect the joint and edges before precise electronics work to prevent contamination or damage.
