Impact wrench Hoozar IW20BL 1/2" brushless 18V with 4.0Ah battery, 600 N·m torque

The Hoozar IW20BL 1/2" brushless impact wrench is a cordless, battery-powered tool with an 18V nominal voltage and a single 4.0Ah lithium battery. It provides up to 600 N·m of torque through a compact 1/2" drive, enabling fastening and loosening of bolts and nuts in automotive, workshop and construction environments. The brushless motor and variable speed control support efficient torque delivery while extending motor life and preserving battery runtime.

Advantages

The brushless motor design reduces maintenance and increases efficiency compared with brushed motors, while the 18V battery system and 4.0Ah capacity provide a balance of runtime and portability. With a rated peak torque of up to 600 N·m and a compact 1/2" square drive, the tool offers high tightening and loosening performance in a form factor suited to confined spaces. Variable speed control allows tailored power output for different fastener sizes and materials.

Suitable for

• Automotive repair and tire changing
• General workshop assembly and disassembly
• Construction site fastening and maintenance
• Mobile repair and field service tasks

Key specifications

• Power type: Cordless, battery-powered (18V nominal)
• Motor: Brushless
• Battery capacity: 4.0 Ah (one battery included)
• Drive size: 1/2" square drive
• Maximum torque: Up to 600 N·m
• Speed control: Variable speed trigger

How to use

Fit the appropriate 1/2" socket to the square drive, insert the charged 4.0Ah battery into the tool and select the desired speed via the variable trigger. Position the socket over the fastener, apply steady pressure and squeeze the trigger to start. Release the trigger to stop. For tightening, apply controlled bursts and check fastener torque as required using a torque wrench when precision is necessary. For loosening, ensure secure footing and a stable grip to control reaction torque.

Usage recommendations

Use recommended socket sizes and impact-rated accessories to avoid damage. Keep the battery charged and store it in a dry, moderate-temperature place. Allow the motor to cool if working on continuous heavy-duty tasks and follow standard safety practices: wear eye protection, keep bystanders clear, and secure workpieces before operating the tool.
