Diagonal pliers Knipex 74 02 250

The Knipex 74 02 250 diagonal pliers are heavy-duty cutting tools forged from chrome vanadium steel and oil-hardened for extended service life. At 250 mm length, they combine a high cutting performance with ergonomic handling; the cutting edges are induction hardened to approximately 64 HRC to ensure precise cuts even on hard wires such as piano wire. These pliers are suitable for electrical and general workshop use where robust, reliable cutting is required.

Advantages

High cutting performance with minimal effort achieved by optimised cutting edge angle and transmission ratio. Precision cutting edges are induction hardened (approx. 64 HRC) to cut all sorts of wire, including piano wire. Manufactured from chrome vanadium heavy-duty steel, forged and oil-hardened for durability. The 250 mm length provides a balance between leverage and access for a wide range of cutting tasks.

Suitable for

• Cutting copper conductors up to 16 mm²
• Cutting aluminium conductors up to 35 mm²
• Cutting various hard and soft wires, including piano wire
• Electrical installation and general workshop cutting tasks

How to use

Position the cutting edges around the wire close to the joint you intend to cut. Apply steady, controlled pressure on the handles to make a clean cut; the tool’s transmission ratio and hardened cutting edges reduce the effort required. For thicker conductors, ensure the correct section size (copper up to 16 mm², aluminium up to 35 mm²) and cut in one decisive motion where possible to avoid deforming the conductor. Keep hands clear of the jaws while cutting and store the pliers in a dry place after use.

Recommendations

Use the pliers only within the specified conductor size limits. Do not use for cutting live electrical conductors. Regularly clean and lightly oil the joint to maintain smooth movement and check cutting edges for wear; replace the tool if the cutting performance deteriorates.
