Product Introduction

Unrivaled Breakaway Torque for Heavy Industry

The high torque cordless impact wrench is the ultimate power solution for professionals dealing with stubborn, rusted, or high-tensile fasteners. Engineered for heavy industrial use, this tool delivers a staggering breakaway torque exceeding 1200Nm, making it capable of handling tasks that previously required pneumatic lines. The high-efficiency brushless motor is designed to withstand extreme current draws during peak impact cycles, ensuring that the tool doesn't stall when encountering maximum resistance in structural steel or heavy equipment maintenance.

At the heart of its destructive power is a massive hammer and anvil mechanism forged from premium-grade molybdenum steel. This ensures maximum kinetic energy transfer with every blow, while the brushless controller precisely manages the motor's timing to synchronize with the mechanical impacts. Unlike traditional wrenches, our model features a multi-stage power selection system, allowing users to drop the torque for smaller bolts while retaining the ability to unleash full power for structural lug nuts or large diameter anchors. This digital control prevents over-tightening and protects the integrity of the fastener.

Ergonomics play a vital role in managing the immense forces generated by this tool. We have integrated an advanced vibration-isolation system that separates the handle from the motor housing, significantly reducing the shock felt by the operator's wrist and arm. The 1/2" square drive features a robust friction ring (hog ring) or detent pin system for secure socket retention, essential for safety when working at heights or in busy workshops. The reinforced aluminum gear housing provides superior heat dissipation, ensuring the tool remains within safe operating temperatures during back-to-back heavy-duty applications.

This wrench is built for the harshest environments, from outdoor construction sites to greasy automotive bays. The housing is made of chemical-resistant materials that won't degrade when exposed to common industrial solvents or oils. Integrated LED lighting provides a wide-angle beam to illuminate the entire work area, ensuring accurate socket placement even in the dark undercarriages of heavy trucks. For industrial technicians and heavy equipment mechanics, this cordless impact wrench provides the freedom of mobility without compromising on the raw power required for the toughest jobs.
