Needing to buy a drill? Today we will teach you everything that is essential when purchasing this utensil that is practically mandatory in any home or professional environment!
The drill is the most useful and necessary power tool. It helps you place shelves, assemble furniture, fix cabinets and other objects that need to be hung. At different times, you will need to have a drill. In addition to this domestic utility, it can also be used for work with carpentry, handicrafts, as furniture assembler or handyman.
But what is the ideal model for each use? How to choose the drill that best suits your needs? In the next lines of this article, we will take all the doubts you may have about this tool!
First, the most important
- There are three most common types of drills on the market: impact, non-impact and screwdrivers. Some models have more than one function. Their recommended uses are different.
- As much as the most traditional use is domestic, on walls, drills can pierce concrete, wood, metal, plastic, glass, among others. But it is necessary to choose the appropriate model and the correct drills.
- Most drills cost between R $ 200 and R $ 300. A good model below this has an exceptional cost-benefit ratio. Above, it is necessary to have great specifications to be a good investment.

Many types of drills are available on the market. They can be more suitable for home or professional use, serve different types of surfaces and other specifications.
We selected the outstanding models that should certainly be taken into account when purchasing:
As you may have noticed, there are several different types of drill. What does each of them mean? What are the main usage recommendations for them?
Now, let’s take all your doubts about which drill is best for you! Thus, the ideal machine can be purchased for your personal or professional needs.
What is a drill and what is it for?
Have you ever needed to hang a painting on a wall? Assemble furniture? Place shelves in your home? Work with holes in wood, concrete or metal for any reason?
All of this requires the use of a drill. These machines work with drills that produce a great rotation as the trigger is pulled and, with that, cross the desired surface.
Then, a dowel or screw should be placed in the hole made and fix the desired object or material. Use is quite simple. It usually does not require a great deal of manual skill or handling knowledge. This changes only in professional situations.
It is very difficult not to use a drill in any domestic situation. So we say that this is the most useful and necessary power tool in the world today. The big question is how to choose the one that best fits the needs of each one!
Did you know that the drill was registered in 1889? Its first model launched in 1895. Despite this, the tool was still very precarious. The name behind the improvement of this tool is quite famous: Henry Ford.
For his car assembly line, Ford needed efficient drills. Thus, it encouraged the research, development and modernization of these tools. In 1917, Samuel Duncan Black and Alonzo Decker (recognize surnames?) Created the first electric model.
Impact drill, without impact or screwdriver?
In the models mentioned above, we show both impact and non-impact drills, in addition to screwdrivers. In addition, some of them have a dual function. What is the use of each of these types?
- Impact drills . They are the most recommended for home use. This is because they are the most recommended for drilling into walls (concrete, brick blocks and the like). In addition to the rotation, it makes small punches on the surface, facilitating drilling.
- Drill without impact . Use only your rotation to drill. You can even drill a wall with one of these, but this usually requires a Herculean effort. This type is recommended for work with wood, plastic and softer materials, in general.
- Screwdriver . It makes it easier to insert the screws, extinguishing the manual work of using the screwdriver. They are mainly professionals (for furniture assemblers, for example), but they also help with domestic service.
Below, a table with more specifications on each of the three types:
How to use the drills?
It is no use knowing just which drill is right for you. It is also necessary to understand the use of drills well. It is with them that the holes are drilled and choosing the right drill will make your job much easier.
Every drill comes with the chuck, part of the end that holds the drill, and the chuck key, which opens and closes the drill bit to replace the drill. Use is quite easy and intuitive.
From there, you need to know what the drills are for your job. Some drill models come with several of them, others require you to make purchases separately.
First, you need to know that there are drills for each type of material. We highlight concrete, wood, metal and glass. Using the wrong drill is unlikely to result in a job well done.
The second issue is the size of the required hole. Depending on the screws and bushings you have at hand and the need for the type of work, the drills will need to be larger or smaller, generating differences in the diameter of the perforations.
A set of drill bits for concrete, the most common material to be drilled, brings pieces with a diameter between 3 and 13 mm. You will need to assess the one that best fits your situation!

Electric drills or battery?
At first, the choice between an electric drill or battery can seem trivial. But in fact, in a deeper look, it can also be related to the type of work you are going to do.
For example: if you are going to use your tool in places that are difficult to access, which may not have easy plugs, you will need a battery model. Electric ones usually have short wires. Extensions, therefore, may not be sufficient.
Weight also influences: due to the lack of wires and electrical compartments, battery models will be lighter. In a long and repetitive job, it can make a difference.
The main advantage of an electric model is practicality. If the use is domestic, with easy access to the electricity grid, you will save yourself the constant work of recharging batteries and waiting for them to be ready for use.
In the case of battery drills, two types can be found. Lithium ion batteries are more modern, not susceptible to addiction and have better performance. It is a superior choice.
Below, see a table with the advantages and disadvantages of each model:
What extra functions can a drill have?
There are some functions that a drill brings that can make your job easier. Among them, the most important are reversible turning and speed adjustment.
None of them are mandatory or will influence if you intend to have a home tool for eventual use. But having a tool with these features can make your life easier in certain situations.
The reversible swing allows the drilling process to be easier. This is because changing the direction of the drill improves friction with the material, preventing saturation. There will be a very small time gain in the service.
Another advantage is when the drill is removed from the hole. Eventually, it can get a little stuck and the inversion of the direction of rotation will make it come out easily.
In a model with no speed adjustment, drilling occurs steadily as the finger pulls the trigger. There is no control over how fast the drill will turn, it depends on what it will find ahead.
When this system exists, however, the speed gain also happens. However, this is a system that should be used with caution: sometimes the drill can get stuck in a wall because it has found foreign materials inside it, for example.
If you are drilling through a wall and notice that the drill bit is no more than a certain depth, stop and assess whether the chosen location is not where pipes or electrical conduits go. This is very important to avoid accidents!
The simplest models are the cheapest. Therefore, impactless drills will be at the bottom of the price scale. With much luck, you will find some model in the range of R $ 70, but most will be above R $ 100.
Drills of good quality, whether impact, without impact or with more than one function, will cost between R $ 200 and R $ 300. Models of quality below that present exceptional cost-benefit!
Don’t be alarmed: for professional use and in extreme situations, there are drills up to R $ 7,000. High quality domestic models that accompany items such as suitcases, brushes and great drills can reach the four digits.
Where to buy?
Building material houses, such as Telhanorte, usually bring many options. Electrical stores can be cheaper and more proliferated in smaller neighborhoods and cities.
If your option is to purchase over the Internet, in addition to the e-commerces of the aforementioned stores, we recommend the Amazon. Both bring a huge range of models, allowing you to choose the one that makes the most sense for you.
Purchasing criteria: Factors to take into account when buying a drill
In addition to everything we have already mentioned, there are some criteria that may be important at the time of purchase. We chose some of them so that you can make a good comparison:
- Rotations per minute
- Additional items
Below, we will explain in more detail the importance of each one!
Most electric drills are not bivolt. So you need to know what the standard voltage in your city is – 220 or 110 volts – to make the right choice. An error here can make your tool useless.
A 220 volt device does not work in a place with a standard voltage of 110. A 110, worse still, will burn in a place of 220. Battery models usually have bi-volt chargers, but also be sure to check this information. So, you won’t have a headache after purchasing
Drills are not exactly light tools. The standard weight will be between 1 and 2 kg. And this is not irrelevant information: you can spend a lot of time needing to hold it without support during use.
If you believe you are unable to do so, look for lighter models. The same goes for if the use is repeated a lot, for hours a day. The more time you spend wielding the drill, the more difficult it will be to work efficiently.
Again, we remember that battery models are usually lighter than electric ones. If you have doubts on how to use a drill, check out this video from the Manual do Mundo channel, which has all the possible tips.
A tool for home use does not need a very high power. Something between 350 W and 450 W is enough. This will prevent unnecessary consumption of electricity or battery with the service being done in the same way.
Models above that, which can reach 750 W or more, are more suitable for professionals. When a drill is connected for a long time in a row, it needs to have a higher power to withstand the stride.
So be careful with the announcement of very high powers for home models. Sometimes this draws more attention than exerts a real improvement in the use of the product.
Rotations per minute
This is a question that is directly related to power. The more powerful a drill is, the faster it will be able to turn. The numbers can reach up to 1300 revolutions per minute.
However, the same as we said above can be applied here. These very high numbers may call the attention of the unsuspecting, but they do not have much influence on domestic use. You will place a shelf in your room with almost the same efficiency.
The difference really starts to happen when we talk about professional use. There, the speed of rotation can save time in an hour service.
Handling a drill can be tricky. While the finger is on the trigger, it cannot be moved sideways, or “bent”. This can cause the hole to come out diagonally, making it unsuitable for use.
Therefore, some brands have invested in more ergonomic models. They fit better to the human body and provide comfort during use. This reduces the chances of shaking or any other affectation from tiredness.
An ergonomic highlight is the armrest bar that is not being used. If you are going to use the tool for a long time or don’t have the strength to drill holes without shaking, it’s a great choice!
Be sure to check if the chosen model offers extra items. For example, the presence of a briefcase can be important for safer storage. Cardboard boxes tend to wear out over time and can lead to an accident.
Also see if your drill comes with extra drills or not, what sizes and materials are recommended. Saving when purchasing these accessories can be a determining factor for the purchase.
A complete kit for drilling will be very useful in your life. And not having to make a new purchase for every job will save time and money!
