Pulttisakset Knipex CoBolt 71 31 200

The Knipex CoBolt 71 31 200 bolt cutter pliers are compact, heavy‑duty cutting pliers designed for precise shearing of soft and hard wire, including piano wire. Forged from chrome‑vanadium steel and oil‑hardened, the tool features induction‑hardened cutting edges with an approximate hardness of 64 HRC. The model includes a gripping surface below the joint for holding and pulling wires from about 1.0 mm diameter.

Advantages

Precision cutting edges and the most efficient joint design deliver high cutting performance while keeping the tool compact. Induction hardening raises the cutting edge hardness to around 64 HRC for long service life when cutting bolts, nails, rivets and similar materials up to 5.2 mm diameter. The chrome‑vanadium forged construction and oil hardening ensure durability and resistance to wear.

Suitable for

• Cutting bolts, nails and rivets up to 5.2 mm diameter
• Shearing soft and hard wire, including piano wire
• Gripping and pulling wires from approx. 1.0 mm diameter
• Maintenance, electrical and general workshop tasks requiring precise cuts

How to use

Position the cutting edges around the material to be cut, keeping the tool perpendicular to the workpiece for a clean shear. For wires, place the material close to the joint to use the leverage and reduce required force; use the gripping surface below the joint to hold or pull wires from about 1.0 mm diameter. Apply steady pressure to close the handles until the cut is complete. Inspect the cutting edges periodically for wear and avoid cutting hardened steel beyond the specified capacity.

Recommendations

The tool is intended for cutting tasks up to the stated 5.2 mm diameter. Do not use the pliers on materials harder than recommended or for prying; store in a dry place and keep cutting edges clean and lightly oiled to maintain performance and service life.
