The 2-speed gearbox has a low of 0-450 and a high of 0-1,500rpm plus 20 torque settings that allow for accurate screwdriving.

Whether you're a professional contractor or a DIY enthusiast, our impact drivers and wrenches are sure to become essential tools in your toolkit. I would just like to add that I have a rather large collection of cordless Drills and their batteries from NiCad to Lithium from the earliest days of this technology. The same concerns don't apply on DC from a battery, or indeed from an airline which was the traditional power source. With features like variable speed settings and quick-change chucks, impact drivers are versatile and easy to use. Cela des mois que je l'utilise : la gâchette n'accelère pas trop vite donc peut être utilisée pour des petites vis, comme pour des grosses vis.Thus using any torque numbers from an impact driver in your quest for a clutched driver is a mistake. Impact drivers have a large amount of torque, but they are not designed to be used like regular drills or hammer drills.

The corded hammer drill I bought 25 years ago is still working as it did when I bought it, the cordless I bought then is useless now. This means they last for a while (and fast to recharge) and the batteries are generally ready to use when needed. To greatly simplify, AC electric motors work best at constant speed and torque, outside of that there is more current flowing through the cable than the power rating indicates - they're taking power from the mains at some points and actively giving it back at others. Es como el taladro de impacto que se usa para cambiar las ruedas de los coches en los talleres, y es algo espectacular, cómo y efectivo.
