Cordless impact drivers are designed for the quick insertion and removal of screws as well as drilling holes.
Due to the much higher level of torque they produce compared with cordless drill drivers, they are particularly suited to the following:
Driving large screws, bolts and other fasteners
Cordless impact drivers are ideal for applications such as:
Driving lag bolts and screws. These are very large fasteners which are often used to bear a great deal of weight (holding together decking, or mounting a heavy object on a wall)
Installing items such as cabinets, using long screws
Repetitive driving
Because they can deliver high torque and speed simultaneously, cordless impact drivers are often used for tasks involving the repetitive driving of screws or fasteners. Examples include:
Laying decking
The assembly of metal frame constructions
Working on tougher materials
Due to the high level of torque produced by the impact function, cordless impact drivers are also a popular choice when working on tough materials such as hardwood, metal and plastic.
