Speed and Torque
Speed and torque |
||||
|
|
||||
 |
A cordless drill driver is operated using the speed control trigger. | |||
 |
Squeezing the trigger starts the chuck turning. The further you pull the trigger in, the faster the tool will go, but the less torque it will deliver.
The more you release the trigger, the slower the drill driver will go, but the more torque it will deliver. This is because the motor’s power is a combination of torque and speed, so the two have an inverse relationship (meaning that when one increases, the other decreases and visa versa). |

 |
Releasing the trigger completely stops the drill driver. | |||
What RPM should I look for? |
||||
 |
A cordless drill driver can have a high RPM (Rotations Per Minute) but it will not necessarily complete tasks quicker than one with a low RPM, unless it also has a high level of torque.
If you want to work with tougher materials and larger screws, then look for a cordless drill driver with a high level of torque and high rpm. |
