How Does the Torque Numbering Sequence on a Drill Work?
The torque numbering sequence is a simple way of letting you choose the strain you want to put on a nut or bolt before the drill lets the clutch slip. This prevents accidental shearing of the bolt or the bolt pulling the nut through the material.
How Do You Change the Torque Setting on a Drill?
Changing the torque setting on most drills is a straightforward process. But you still need to know the torque limits of the screw or bolt you are tightening.
What Are the Important Factors That Contribute to the Torque Setting?
As you increase the torque setting, the drill will respond by making it more difficult to control. You will also want to use a lower setting on small screws and bolts. Each drill is different, so it is a good idea to practice before committing to a setting.
Can You Leave Your Drill on One Torque Setting?
You can leave your drill on one setting, and many people have a preferred torque. Large bolts on thick screws on dense woods and metals will all need a higher torque. The middle torque setting should cover most situations, but if in doubt, test it out.
What Other Factors Contribute to the Torque Setting?
The torque setting on a drill is an indication of when the clutch will cut out. These divisions are not a representation of torque as they are a percentage of what the drill can do. Drills big or small will have the same numbers, yet no one drill is the same.
Are All Drills the Same?
Electric drills are as diverse as the situations that you need them for. Some drills need higher speeds to get through a tough material without ripping it up. Others have hammer modes for getting through thick concrete.
What Would You Use the Clutch Setting For?
You will want to use the lowest setting on thin plastics, woods, and metal to avoid pull-through. It is better to start with a lower torque setting than what you need.
