Diagonal Cutter Knipex High Leverage 160 mm, model 74 01 160 SB

Knipex High Leverage Diagonal Cutter 160 mm (model 74 01 160 SB) is a compact diagonal power cutter designed for precise cutting of soft and hard wires, including piano wire. The tool features a narrow head for access in confined spaces and forged, oil-hardened chrome-vanadium steel construction for extended service life. Induction-hardened cutting edges ensure reliable, clean cuts even on thin copper conductors.

Advantages

The high-leverage design provides high cutting performance with reduced physical effort through an optimized power conversion ratio. Inductively hardened precision cutting edges (approx. 62–64 HRC) give long-lasting sharpness for clean cuts on both soft and hard wires. The narrow head style enables work in hard-to-reach areas while the forged pivot axis and robust handles ensure durability during repeated use.

Suitable for

• Cutting electrical wires and thin copper conductors
• Trimming piano wire and other hard wires
• Maintenance, workshop and general-purpose electrical work
• Use in confined or hard-to-reach spaces

Key specifications

How to use

Position the wire as close to the tip of the cutting edges as practical for the cleanest cut. Apply steady pressure on the handles to use the high-leverage mechanism, keeping fingers clear of the cutting zone. Use appropriate personal protective equipment such as safety glasses when cutting hard wires or piano wire. After use, wipe the tool clean and store in a dry place to maintain the hardened cutting edges and joint function.

Usage recommendations

For best results with the Knipex High Leverage Diagonal Cutter, use it within its intended wire range: use the tip area for thin copper conductors and the main cutting zone for harder wires, and avoid cutting hardened rivets or materials beyond the tool's design to preserve edge hardness and tool life.
