What You'll Learn
Torque and power
Torque is the force that causes an object to rotate, and it is measured in Newton Metres (Nm). The higher the number in newton metres, the more twisting force the drill can deliver. The clutch setting is the most critical aspect to master when using a drill. The clutch setting is used to calibrate the clutch so that it can deliver a specific torque range. The greater the power tool torque, the higher the number on the collar.
Drills with high torque levels can be dangerous if you're not careful. If you are driving screws into a soft material like wood, it is recommended to turn down the torque. If you leave your drill at top torque, you may have less control over how deep you are driving the screw, which can cause you to overshoot and split the wood. When driving screws into harder materials, you will need to go slower and apply more torque.
Corded drills generally offer higher torque than cordless drills, making them suitable for heavy-duty applications. The absence of a power cord on a cordless drill allows for greater mobility and flexibility, making it a popular choice for working in tight spaces or outdoor environments where access to power outlets is limited.
The type of material you are working with will determine the torque level you need. Torque won't be an issue if you're mostly dealing with wood. Even drills with the lowest torque settings won't have much trouble drilling through wood. However, when connecting metal to metal, especially stainless steel, you will need to use a higher torque level.
