One of the most important things an electric drill does is making holes, especially in hard surfaces like plastic, walls, and wood. The hole will later become a place for nails or screws to be installed.
In the past, people used their muscles to power drills. Of course, the work of making holes with the drill takes a long time and is tiring. But now there are electric drills that use electricity to power them.
No wonder that currently there are various kinds of electric drills with various forms and functions. If you’re looking for an electric drill, the tips below will help you choose the right one.
1. Find out the Types of Electric Drills
There are many different kinds of electric drills on the market, so you can find one that works for you. Because of this, it is very important to know ahead of time what kinds of electric drills will work best for the work and objects that will be done.
Hand Drill
A hand drill also called a drill driver, is a type of electric drill that is used quite often. It is small, which makes it look useful, and it comes in a set with several drill bits.
Hand drills can do more than just make holes. They can also be used to tighten and loosen bolts, and cut, and sharpen things that are already sharp. Some hand drills have clutches that can be changed so that the bolts or materials being used don’t get broken.
Portable Electric Drill
As the name suggests, portable electric drills are a kind of electric drill that is small and easy to carry around. Not only that, but portable electric drills are light, small, and easy to hold. This makes them good for women and people who are just starting.
Compared to other types of electric drills, the price is also pretty low. Even so, you shouldn’t use a portable electric drill to make holes in hard surfaces or large sizes. This is because it has very little engine power. But portable electric drills can be used to tighten bolts on furniture or other small things that have already been put together.
Concrete Drill
A concrete drill or impact drill is an electric drill that is suitable for heavy work such as carpentry, screw planting, and dismantling because it has more power than a hand drill. This drill works by stomping while turning bolts to provide ease in installing long screws.
Even some types of concrete drills have been equipped with a hammer drill function that will provide a stronger pounding when installing bolts. With its great power, using a concrete drill needs to be done carefully so as not to damage the bolt thread.
2. Note the Torque Value
Another thing to consider when choosing an electric drill is the torque value. Torque refers to the ability of an electric drill to tighten bolts measured in units of newtons per meter (N/m). The greater the torque value of the electric drill, the stronger the drill is in tightening the bolt.
For an industrial or professional scale, it is better to choose an electric drill with a torque value of up to 70 N/m. While at the household level, simply choose an electric drill with a torque between 20 to 49 N/m.
3. Speed Settings Available
When choosing an electric drill, you might want to think about whether or not it has different speed settings. The speed setting on an electric drill has something to do with how well and quickly the work gets done.
For example, if you want to make holes in wood, you should use an electric drill that turns at about 2,000 rpm. And to make holes in metal, use an electric drill with a speed of more than 2,000 rpm.
The size of the drill bit on the electric drill can also change how fast it spins. If the drill bit is small, it’s best to choose a machine that can spin as fast as possible.
4. Choose a Drilling Machine that has a Rotation Variation Movement
The drill bit is designed to be able to rotate both clockwise and counterclockwise. This is what is meant by “variation of rotation movement.” The different speeds of rotation on this drill bit make it easy to put screws in or take them out of the hole.
5. Choose an Electric Drill from a Trusted Brand
When shopping for an electric drill, it’s also important to make sure it comes from a trusted brand. Most of the time, the brand is known for its quality and durability.
Make sure that the electric drill has a warranty as well as the brand. So, if the electric drill breaks, you can get your money back.
These are some things you can do when you go to buy an electric drill. Also, make sure the item you buy is real and comes from a store you can trust. The information above should be helpful.
