Electric Torque Wrench

Electric Torque Wrench – Detailed Description

An electric torque wrench is a precision power tool designed to apply a specific torque to a fastener (bolt, nut, or screw) using an electric motor. Unlike standard impact wrenches that rely on hammering action, electric torque wrenches deliver controlled, consistent torque, ensuring secure fastening without damaging components.

Power Source

Corded: Operates on direct electricity (110V/220V), ideal for continuous heavy-duty use.

Cordless (Battery-Powered): Uses rechargeable lithium-ion batteries, offering mobility and flexibility in the field.

Torque Control

Equipped with a torque control system (digital or mechanical), allowing precise settings within a defined torque range (e.g., 100–6000 Nm).

Many models feature digital displays for exact torque adjustment and monitoring.

Motor

High-performance brushless or brushed electric motor delivers consistent power.

It Brushless motors provide higher efficiency, less heat, and longer tool life.

Gearbox / Reduction Mechanism

Multi-stage planetary gear system reduces speed and increases torque output.

Ensures smooth, accurate, and vibration-free operation

Advantages

✅ High torque output with precision.

✅ Eliminates over-tightening or under-tightening.

✅ Reduces operator fatigue compared to manual wrenches.

✅ Quiet and vibration-free compared to pneumatic impact tools.

✅ Digital torque monitoring ensures reliability and repeatability.
