An impact driver is a tool that uses a rotary hammering action to drive screws or bolts.
It is different from a drill because it has a mechanism that allows it to transmit more torque to the screw or bolt. This makes it ideal for use in tight spaces or when there is insufficient clearance to use a regular drill.

When do you use an impact driver?
An impact driver is the ideal tool for driving screws or bolts into hard materials such as concrete, brick, or stone. It is also useful for driving large screws or bolts that would be difficult to drive with a regular drill.
How does an impact driver work?
An impact driver has a hammering action that enables it to deliver more torque to the screw or bolt. This makes it ideal for use in tight spaces or when there is insufficient clearance to use a regular drill.
