21V Brushless Electric Impact Wrench with 500W Motor and Lithium Battery for Cordless Use

This 21V brushless electric impact wrench combines a powerful 500W motor with a lightweight lithium battery, giving you the torque you need for automotive repairs, construction fastening, and workshop tasks without being tethered to a power outlet. The brushless design reduces friction and wear, helping the tool maintain consistent performance over time. With a 12.4mm chuck, it accepts standard impact-rated sockets and bits, making it a versatile addition to any toolbox. Multiple model options allow you to choose the torque output that matches your workload, from light-duty to heavy-duty applications.

Power System and Motor Design

The impact wrench uses a brushless motor, which delivers efficient power transfer and requires less maintenance than traditional brushed motors. The 21V lithium battery provides reliable energy storage, supporting cordless operation across various jobsites.

Brushless Motor

The 500W brushless motor generates strong rotational force while running cooler and more efficiently than brushed alternatives. This reduces energy loss and extends the runtime per battery charge, making it suitable for repetitive fastening and loosening tasks.

21V Lithium Battery

The 21V lithium battery pack powers the tool without needing a cord, allowing you to work in garages, construction sites, or outdoor areas where power outlets are unavailable. The battery is rechargeable and included with the purchase.

Chuck and Bit Compatibility

The 12.4mm chuck accepts standard hex-shank impact bits and sockets. This size is common among electric impact wrenches, ensuring you can find replacement accessories easily at most hardware suppliers.

Performance and Torque Options

The tool is available in multiple configurations that vary by maximum torque, voltage compatibility (EU or US), and battery cell count. This flexibility lets you select the model that best fits your specific application needs.

Maximum Torque Range

Depending on the model chosen, the impact wrench delivers maximum torque values between 301 and 309 Nm. Higher torque models are suited for loosening rusted or overtightened bolts, while lower torque settings prevent over-fastening on delicate materials.

Regional Voltage Compatibility

Models are offered with EU or US power specifications, ensuring the battery charger and tool work with local electrical standards. Check your region before ordering to ensure compatibility.

Battery Cell Options

Some models come with a 5-cell battery pack, while others include a 10-cell pack for extended runtime. The pack size affects how long you can work before needing a recharge, with the 10-cell option offering longer operation per charge cycle.

Uses and Applications

This impact wrench is designed for tasks that require high fastening torque, such as tyre changes, machinery assembly, and structural bolting. Its portability and power make it appropriate for both professional and DIY use.

Automotive Repair

Use the wrench to remove and install lug nuts, suspension bolts, and engine mounts. The impact mechanism reduces the physical effort needed to break free stubborn fasteners, speeding up workshop workflow.

Construction and Assembly

In construction settings, the tool can drive lag bolts into timber, secure metal brackets, or fasten scaffolding components. The cordless design allows movement around the jobsite without dragging extension leads.

Home Workshop and DIY

For home enthusiasts, the impact wrench handles furniture assembly, shed building, and general maintenance tasks. The brushless motor keeps noise and vibration lower than older brushed tools, improving comfort during use.

Value and Maintenance

The brushless motor reduces internal wear, meaning fewer part replacements over the tool's lifespan. The lithium battery holds charge well when not in use, and the tool requires minimal routine care beyond cleaning and occasional chuck inspection.

Low Maintenance Operation

Because the brushless motor has no brushes to replace, the main moving parts are sealed and lubricated for life. Keep the air vents clear of dust and debris to prevent overheating.

Why Choose This Impact Wrench

This tool combines a 500W brushless motor with a 21V battery system in a package that suits professional and serious DIY users. The choice of torque output and battery capacity lets you match the tool to your usual workload without paying for unnecessary power.
