Knipex 74 05 250 Side Cutter

The Knipex 74 05 250 diagonal pliers are heavy‑duty cutting tools made from forged chrome‑vanadium steel with oil hardening. At 250 mm overall length and approximately 440 g weight, they combine durability with comfortable handling. Precision cutting edges are induction hardened to about 64 HRC for long life and reliable performance when cutting a wide range of wires, including piano wire. The tool delivers high cutting performance with minimal effort due to the optimized coordination of cutting edge angle and transmission ratio. The 250 mm size is suitable for copper conductors up to 16 mm² and aluminium conductors up to 35 mm².

Advantages

The pliers feature precision cutting edges induction hardened to approx. 64 HRC for extended wear resistance. Forged chrome‑vanadium heavy‑duty steel with oil hardening provides high strength and toughness for continuous, demanding use. Optimized cutting edge geometry and transmission ratio reduce user effort while maintaining clean, precise cuts. A plastic handle ensures a secure grip and comfortable handling during extended tasks.

Suitable for

• Copper conductors up to 16 mm²
• Aluminium conductors up to 35 mm²

How to use

Position the diagonal pliers so the wire is seated as close as possible to the cutting edge. Apply steady pressure to the handles until the wire is cut through in one clean action. For thick conductors use the central part of the cutting edge and avoid twisting motions. After cutting hard materials such as piano wire, inspect the cutting edges for damage and remove any metal debris from the joint area.

Recommendations

Use the pliers only for cutting tasks for which they are specified. Do not use them to cut hardened bolts, rivets or very abrasive materials beyond the stated capacities. Keep the tool clean and lightly lubricate the joint periodically to maintain smooth operation and long service life.
