Professional Grade 21V Cordless Impact Wrench Kit with 4.0Ah Battery and Charger for Construction

It's not the lightest tool on the market at about 3.2 kilos, so you'll feel it on an overhead job after a while, but the brushless motor and 21V system basically mean you get consistent torque throughout the battery's charge cycle, which matters more for sustained work than a few grams of weight savings.

The 300n.M max torque is better for general construction fastening than for breaking seized bolts on heavy equiment—we usually stock these for framing crews who need reliable driving into dimensional lumber rather than automotive guys fighting rust.

You get two 4.0Ah batteries in the kit, and the charger takes about an hour or so to top one off form empty, which is pretty standard for this class, though we've had some customers mention they wish teh charging temperature range was wider than 10°C to 40°C when working outdoors in winter.

What it does is deliver up to 2800 RPM and 3200 impacts per minute, and the variable speed trigger on these is actually smoother than some of the competitor models we've handled, giving you decent control for starting screws before you hammer home.

The warranty is 6 months, which isn't but reflects the price point—most buyers go with this for smaller framing companies or DIY-heavy crews who aren't running them eight hours a day, and the OEM/ODM customization option is available if you want your branding on housing or a different battery configuration.
