1. Battery |
||||
 |
Every cordless impact driver is powered by a rechargeable battery. | |||
2. Speed control trigger |
||||
 |
The battery’s electrical current is transferred to the motor through the speed control trigger. When you pull the speed control trigger, a switch inside the tool conducts electricity from the rechargeable battery to the motor. | |||
3. The motor |
||||
 |
A motor converts the battery’s electrical current into the rotational energy needed to turn the chuck. This power is a combination of torque and speed, and is measured in watts. | |||
4. Gearbox, hammer and anvil |
||||
 |
The motor’s power is transferred through the gearbox to a hammer and anvil mechanism.
When a high level of torque is needed to drive in screws, the hammer begins striking the side of the anvil which then delivers a strong rotational force to the screwdriver bit to help drive in the screws. For a more in depth guide, see our section: |
