Flat round nose pliers Wiha 27422 — professional electric insulated hand tool

Flat round nose pliers Wiha 27422 — professional electric insulated hand tool combine a dual-profile jaw with electrical insulation to support precise bending, shaping and holding of wires and small components. The tool is designed for electrical and electronic work where access to tight spaces and controlled manipulation are required, providing a flat gripping face and a rounded nose for forming loops and gentle curves without damaging conductor insulation.

Advantages

The pliers offer two complementary gripping surfaces—flat and round—enabling both secure holding and accurate bending. Electric insulation reduces the risk of accidental contact with live conductors when used within its rated protection limits. Precision-machined jaws ensure consistent alignment and reduce slippage when handling thin wire or small parts. The ergonomic handle shape supports extended use with reduced hand fatigue and improves control during delicate tasks.

Suitable for

• Bending and forming copper, aluminum and small gauge wires
• Creating loops and curved wire ends for connectors and terminals
• Holding small components during assembly and repair
• Electrical maintenance, installations and electronic assembly work

Key specifications

• Dual-profile jaws: flat surface and rounded nose for versatile manipulation
• Insulated handles designed for electrical work to reduce risk of contact with live parts
• Precision-ground jaw faces for consistent grip and low slippage
• Compact geometry suitable for access into confined or recessed areas
• Ergonomic handle design to improve comfort and control

How to use

Grip the pliers by the insulated handles and position the jaw profile that best matches the task: use the flat face for secure holding and straight bends, or use the rounded nose to form loops and curved shapes. Align the wire or component between the jaw faces, apply steady pressure to hold or bend, and make incremental adjustments to achieve the required shape. For operations near live circuits, verify that the work is de-energized where possible and follow safety procedures related to insulated tools.

Recommendations

Regularly inspect the insulation and jaw condition before use; do not use if insulation is damaged or if jaws are excessively worn. Use the pliers within their intended mechanical and electrical limits, and keep the tool clean and dry. When working on electrical systems, comply with applicable safety regulations and use appropriate personal protective equipment.
