The 1/4' hex drive impact drivers we supply are available in both cordless and powered versions. Impact drivers are similar to screwdrivers but with the added feature of providing rotational and downward force to help tighten and loosen screws. An impact driver is ideal when some additional force is required for either tightening or loosening.
- Choosing your power source: The first choice is between a mains (110v or 240v) or a cordless tool. 240v tools are used with normal mains power whilst 110v tools are used on construction sites for safety reasons.
- With regards to cordless (battery powered) tools there are a variety of chemical types; Li-ion is the latest technology, prior to that it was Ni-MH and Ni-Cad was the original. The higher the Ah (Ampere hours) the longer the interval between charges; the fewer times you recharge a battery the longer it will last. Some cordless tools can also come without batteries - sometimes referred to as naked, bare units or body only. These tools are supplied without a battery or charger and more often than not without any accessories; as a result they are significantly cheaper in price.
- Additionally there is often a choice between single, 2 or 3 speed gears. Most professional impact drivers have a variable speed function.
