The wrench is equipped with an optimized brushless motor that delivers a peak torque of 550N·m. Compared with traditional brushed motors of the same specification, the brushless structure eliminates carbon brush wear, improving operational efficiency by 30% and extending motor service life to over 600 working hours. The motor maintains stable torque output under continuous high-intensity operation, adapting to heavy-duty fastening tasks.
It is matched with a detachable 5.0Ah lithium battery, supporting 300+ continuous screw tightening operations on a single full charge. The full charging process takes 1.5 hours, which meets the demand for all-day outdoor operation without fixed power supply. The detachable battery design allows users to prepare spare batteries for extended work cycles.
The wrench is designed with three adjustable torque levels, paired with forward and reverse rotation control. Users can select appropriate torque parameters according to bolt specifications and operation requirements, adapting to different fastening and disassembly tasks of various bolts. The adjustment switch is placed within easy reach of the holding hand, supporting quick switching during operation.
The compact body weighs only 1.8kg, reducing arm load during long-term holding. The handle is covered with non-slip rubber material, which cuts vibration transmission by 25% compared with standard hard plastic handles. This design effectively lowers operator fatigue during long-hour continuous work, and improves holding stability in oily and dusty working environments.
Hanbon Hardware operates under the ISO 9001 quality management system. Its products are exported to more than 40 countries and served by over 20,000 dealers worldwide. Each impact wrench undergoes 1200+ torque and durability tests before delivery, covering motor performance, structural stability and battery safety. The production process aligns with prevailing global power tool safety manufacturing specifications.
This impact wrench is used for quick tightening and removal of automobile tire bolts in auto repair shops and fleet maintenance centers. It replaces manual wrenches to reduce physical labor of maintenance personnel, and improves work efficiency of tire replacement and chassis maintenance work.
It is suitable for fastening high-strength bolts on steel frames in construction sites. The high-torque output meets the torque requirements of steel structure engineering installation, and the cordless design adapts to high-altitude and open construction sites without fixed power supply.
For outdoor engineering sites, municipal maintenance and farm equipment repair work without fixed power supply, this cordless wrench can complete bolt disassembly and assembly work flexibly. Its long battery life supports full-day outdoor operation without frequent charging.
The wrench meets the high-efficiency fastening needs of large furniture, storage shelves and mechanical equipment assembly work. The adjustable torque function avoids bolt damage caused by excessive force, and improves assembly consistency for batch installation projects.
