Product Overview

The KNIPEX High Leverage Concreters' Nippers (Part No. 99 11 250) are the gold standard for professionals tying steel reinforcing bar (rebar) in concrete construction. Engineered to twist and cut thick binding wire in a single, fluid operation, these 10-inch (250mm) nippers drastically reduce the physical strain of highly repetitive wire-tying tasks.

What sets the 99 Series apart is its highly efficient high-leverage joint design, which reduces the manual effort required to cut by up to 25% compared to conventional concreters' nippers of the same size. Combined with an extra-slim head profile designed to reach deep-mounted reinforcing steel and cutting edges induction-hardened to approximately 61 HRC, this tool delivers unmatched durability and performance in harsh construction environments.

Key Features

• High-Leverage Design: The optimized joint geometry positions the rivet closer to the cutting edge, providing maximum mechanical advantage and saving up to 25% of cutting effort.

• Twist & Cut in One Move: Specifically engineered to firmly grip, twist, and seamlessly cut binding wire from the roll in one quick, ergonomic motion.

• Slim Head Profile: The elongated, highly tapered head design allows technicians to easily reach, tie, and snip wire on deep-mounted, densely packed steel rods.

• Induction-Hardened Edges: The cutting edges are additionally hardened to approximately 61 HRC, ensuring long-lasting sharpness even when repeatedly cutting tough binding wire.

• Premium Construction: Forged from high-grade special tool steel and multi-stage oil-hardened for extreme structural rigidity under heavy shock and torsion.

• High-Damping Design: The cutting stroke is highly damped after cutting the wire, significantly reducing the shock traveling into the user's tendons and muscles.

Ideal Use Cases & Applications

• Concrete & Foundation Work: The primary application is rapidly tying and cutting binding wire to secure rebar grids and cages prior to pouring concrete.

• Fencing & Wire Mesh: Excellent for agricultural and commercial fencing contractors who need to twist and cut heavy-gauge tie wire on chain-link or woven wire fences.

• Masonry & Hardscaping: Used heavily by bricklayers and hardscapers for securing wire mesh lath on walls before applying mortar or stucco.

• Auto Body & Collision Industry: To cut the head off rivets

Common Questions (FAQs)

Q: How does this differ from standard end-cutting nippers? 
A: Standard end nippers are primarily designed just to cut or pull nails. Concreters' nippers feature a specific jaw shape designed to grip and twist wire tightly before cutting it, and the 99-series features an extra-slim head to reach into deep rebar cages.

Q: Are the handles on this model insulated for electrical work?
A: No. While the handles are coated in a comfortable red plastic for grip, they are not VDE-tested or insulated against live electrical currents. They are intended for mechanical wire tying and cutting.

Q: Can it cut hardened steel wire or just soft tie wire?
A: The induction-hardened cutting edges (61 HRC) are incredibly tough. While optimized for soft to medium-hard binding wire (up to 3.3mm), it is fully capable of cutting hard wire up to 1.8mm in diameter without damaging the jaws.
