21V Cordless Impact Wrench with 420 Nm Torque

This 21 V cordless impact wrench delivers up to 420 Nm of maximum torque for removing lug nuts and heavy fasteners on cars, motorcycles, pickup trucks and trailers. Its brushless motor provides efficient power delivery and longer tool life. The 2-in-1 work head converts between impact wrench and drill modes without tools. At 1.7 kg it remains manageable for extended use.

4-Speed Control with Reverse Auto-Stop

Four variable speed settings let you match rotation rate to the task, and the trigger stops the tool instantly when released for added safety. The reverse auto-stop function halts rotation once a fastener breaks loose, protecting threads and preventing dropped nuts. This feature can be disabled when continuous reverse drive is needed. An integrated LED illuminates the work area in low light.

10-Cell Lithium Battery and Broad Compatibility

The pack uses ten lithium cells for high capacity, reducing mid-job recharge cycles and charging fully in hours. The system is compatible with DEWALT 20V MAX and Milwaukee M18 batteries, so users invested in those platforms can share packs across tools. The 1/2-inch chuck accepts standard impact sockets and drill bits. Builders needing higher torque or specialised industrial certifications should look elsewhere.

Questions about this item

How often will the 21V lithium battery need replacement with daily use?

The pack contains 10 lithium cells; typical cordless-tool packs last two to three years before capacity drops enough to warrant a new battery.

What stops the motor first during continuous high-torque work?

The 420 Nm brushless motor will hit thermal protection before the 1/2 inch chuck or gearbox reaches a mechanical limit.

How hot and loud does the tool get after an hour of non-stop fastening?

The nylon housing stays warm but not hot, and the brushless motor runs quieter than brushed models; no decibel or surface-temperature figures are published.
