Knipex 74 22 250 High Leverage Diagonal Cutters with Plastic Handles

The Knipex 74 22 250 High Leverage Diagonal Cutters are professional-grade tools engineered for demanding cutting tasks in industrial and workshop environments. Forged from high-quality chromium-vanadium heavy-duty steel and oil-hardened, these pliers are built to withstand continuous, heavy-duty use. The design incorporates a high-leverage joint that optimizes the transmission ratio, allowing for high cutting performance with significantly reduced physical effort.

Advantages

These diagonal cutters offer exceptional durability and precision thanks to their induction-hardened cutting edges, which reach a hardness of approximately 64 HRC. This makes them capable of cutting various types of wire, including piano wire, with ease. The 250 mm length provides an extended lever arm, ensuring optimal force transmission for tougher materials. The ergonomic plastic handles are designed to provide a secure and comfortable grip, reducing hand fatigue during prolonged operation.

Suitable for

• Cutting hard wire and piano wire
• Heavy-duty industrial and workshop applications
• Cutting copper conductors up to 16 mm²
• Cutting aluminium conductors up to 35 mm²

When it may not be suitable

These cutters are not intended for use on live electrical components, as the plastic handles do not provide certified insulation for high-voltage work. Additionally, they may be oversized for delicate electronic assembly tasks where smaller, more precise tools are required.

Key specifications

• Length: 250 mm
• Material: Chromium-vanadium heavy-duty steel
• Cutting edge hardness: Approx. 64 HRC
• Handle type: Plastic
• Cutting capacity: Copper up to 16 mm², Aluminium up to 35 mm²

How to use

To use the cutters, place the wire as close to the joint as possible to maximize the leverage effect. Apply steady pressure to the handles to perform the cut. Ensure the wire is positioned correctly between the cutting edges to prevent slipping. Always keep the tool clean and free of debris to maintain the integrity of the cutting edges.

What to consider before purchase

• Verify the required cutting capacity for your specific wire types
• Ensure the 250 mm size fits your workspace and storage requirements
• Confirm that non-insulated handles are acceptable for your intended work environment

Usage recommendations

Regularly wipe the cutting edges with a light oil to prevent corrosion and ensure smooth operation. Avoid using the pliers as a hammer or prying tool, as this can damage the precision-ground edges.
