The electric drill is a very simple tool that will greatly facilitate our work. Broadly speaking it is only an engine, whose power will depend on the watts (usually), which will perform the task that in normal conditions should make our wrist. Let’s discover how to use an electric drill.
The electric drill usually attaches heads, to match any screw you are working with, and you can also attach “drill bits,” which allows you to drill holes in the surfaces.
You probably need for an electric drill:
Repetitive bolting jobs, such as in construction or assembly. Drilling holes in a wall or other surface.
How to use an electric drill?
The main thing you should know about an electric drill is that you can change the heads. A thread in the beak tightens most modern electric drills. Is that how it works:
- Loosen up.
- Place the head you need in the drill.
To tight. Make sure it is tight. You can tighten it a bit more by holding the large round part just behind the bit, then squeezing the trigger for a second, but be careful not to hurt yourself. Many home drills use keyless chucks, which means you can tighten them by hand. Some drills require the use of a “wrench” to tighten the beak. The key is usually stored in the top of the drill or the handle.
The electric drill has two other important components
There is a button, near the trigger, that tells the drill whether to move forward (to the right) or backward. There is also (in most simulations) a pair configuration. When the torque is set to its lowest (looser) setting, you will tighten the screw until you feel some tension, then start clicking quickly. When the torque is in its highest position, continue to tighten the screw until it comes out or until something bad happens (remove the screw, remove the eye, etc.).
There are different types of drill bits. The most common are commonly used, with a simple head, and can be used for most home projects. Others include swords or flat bits (for building frames with bolt holes in wood), masonry (for concrete), brad tips (for the pin or word jobs) and diamond carbide tipped bits (for drilling porcelain or other hard surfaces).
Tips for using an electric drill
- Use the correct size bit before drilling. To do this, hold your screw with a bit in front of it. See all the threads of the screw behind the bit. In other words, the bit must be the same size as the screw body, but smaller than its threads.
- If you drill a large hole, especially in metal, or with a precise center point, you may need to make a smaller “pilot hole” to help the hole and protect the material from cracks.
- In addition to all the drawbacks of using a screwdriver, power tools have more strength and power than hand tools. Being more powerful, they can damage more quickly their screws, walls, hands, eyes, etc. Be careful when using them, move slowly, wear eye protection.
When using a drill, remember that you can always enlarge the hole, but you can never make it smaller. If you are not sure what bit size to use, you’d better err by using a smaller bit than needed. The solution will be much simpler.
