In high-intensity industrial fields including vehicle maintenance, heavy machinery assembly and steel structure construction, a dependable and high-power cordless impact wrench is vital to improve work efficiency and ensure project quality. Equipped with a brushless motor and delivering a maximum torque of 850N·m, the Changlu ET0513 Industrial Cordless Impact Wrench features professional craftsmanship. It serves as an excellent option for professional users and provides stable and long-lasting power for complex working conditions.
The ET0513 adopts a high-power brushless motor. Compared with conventional brushed motors, it effectively reduces wear and failures and improves energy conversion efficiency, running more steadily with lower noise. It maintains strong power output during prolonged heavy-duty work and enjoys a longer service life, performing well in harsh construction environments with dust and vibration. The tool offers three adjustable torque levels: above 510N·m for furniture assembly and pipe fastening, over 630N·m for vehicle repair and medium-sized equipment assembly, and up to 850N·m for disassembling heavy machinery and steel structure bolts. The multi-level torque design enables flexible switching between precision installation and heavy-duty disassembly, greatly expanding its application range.
This impact wrench also boasts excellent controllability. It has three speed settings of 1200rpm, 1800rpm and 2500rpm, paired with impact frequencies ranging from 1700ipm to 3000ipm. Low speed and low frequency ensure precise fastening and prevent bolt slippage, while high speed and high frequency accelerate disassembly and save working time. The one-button forward and reverse switch is easy to operate for all users. Its standard 1/2 inch anvil is compatible with most mainstream sockets on the market for great versatility.
In terms of battery life and portability, the ET0513 is fitted with a 21V high-voltage system and a 4000mAh large-capacity lithium battery. It supports fast charging and long endurance to meet the demands of all-day continuous work, even at outdoor sites without power supply. The built-in intelligent protection system guards against overcharging, over-discharging and short circuits for enhanced safety and durability. Weighing only 1.70kg, it comes with an ergonomic anti-slip grip to relieve fatigue during long-hour operation. The compact body allows flexible use in narrow spaces such as vehicle undercarriages and equipment interiors.
Manufactured in strict compliance with industrial standards, the wrench features a sturdy drop-resistant housing, an efficient heat dissipation system and a low-noise design. Its modular structure simplifies daily maintenance and cuts long-term costs. Widely applied in auto repair, heavy machinery upkeep, steel structure projects and general installation work, it is a reliable helper for professional operations.
Combining robust power, precise control, long battery life and industrial-grade durability, the Changlu ET0513 solves the common drawbacks of traditional power tools and fully meets the requirements of professional scenarios. It delivers consistent and efficient performance for daily construction and emergency repairs, making it an ideal power tool to boost working efficiency and guarantee construction quality.
