Angle impact driver

Angled impact drivers can be useful when working in tight and confined spaces, where a traditional-style impact driver or screwdriver cannot fit. Impact drivers are like screwdrivers, but are designed to provide an additional force when tightening and loosening screws. One of the key features that you should consider when buying an impact driver is the max torque the device can support.

• Choosing the right battery: Cordless (or battery powered) tools have a variety of chemical battery 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.
