General Description of an Impact Driver
An impact driver is a tool that delivers a strong, sudden rotational and downward force. In conjunction with toughened screwdriver bits and socket sets, they are often used by mechanics to loosen larger screws (bolts) and nuts that are corrosively “frozen” or over-torqued. The direction can also be reversed for situations where screws have to be tightened with torque greater than what a screwdriver can reasonably provide.
Earlier Impact Drivers
Earlier Impact Drivers were basically manual impact drivers with screwdriver bits and adapters which consisted of a heavy outer sleeve that surrounded an inner core splined to it. The spline is curved so that when the user strikes the outer sleeve with a hammer, its downward force works on the spline to produce turning force on the core and any socket or work bit attached to it. The tool translates the heavy rotational inertia of the sleeve to the lighter core to generate large amounts of torque. At the same time, the striking blow from the hammer forces the impact driver down into the screw reducing or eliminating cam out. This characteristic is most beneficial for Philips screws which normally cam out as part of their design. It is less beneficial for flat head, also known as common screws, and is not beneficial at all for most other types of screws.
Another type of impact driver uses a motor to automatically deliver the downward and rotational forces. These have the advantage of greatly increased speed. They are most often used in construction and manufacturing to replace screwdrivers where speed and operator fatigue are an issue. In some situations however, this type falls short since current designs cannot deliver the heavy downward blow of a manual unit. This can be especially true on very stubborn fasteners.
Buyers must also be aware that some tools improperly advertised as impact drivers are actually just impact wrenches. The only way to verify that a motorized impact driver is truly what it claims to be (without taking it apart) is to try it before purchasing.
