A cordless impact drill works similarly to a drill, except that when the driving motor detects resistance, the impact hammer mechanism is activated by pushing an internal spring back, causing the hammer to dive forward and strike the anvil.This mechanism significantly increases torque, allowing you to drill screws through dense, resistant materials with ease.One thing to keep in mind is that because they don’t have a clutch like a cordless drill you’ll have to experiment and practice drilling screws to get the right depth. Although there isn’t much of a learning curve here, it’s worth noting.When using an impact driver, you can connect bits by sliding a 1/4-inch fast connect chuck forward and attaching your bit. It is then secured in position, and screws or nuts can be drilled or fastened as needed.
