For anyone DIY enthusiast A certain curiosity, determination and a good dose of creativity are essential. However, it is also very important to have the basic tools, including the drill. How to choose an ideal drill for each task or for each material to be worked, is therefore essential for the success of the work.

how to choose a drill

For a DIY enthusiast, having the right work tools will help. will allow any of your ideas to materialize. Hence the importance of having the necessary knowledge to know how to choose a drill. There are several criteria that we will use to define what is the ideal exercise for each task. One of them, perhaps the most important, is the material to work with. The second, and this is where we will begin our speech, concerns the conditions of the space in which we will work. Drills are initially divided according to their power source, into two large groups: those with cable and those with wireless. Once we have defined which of the two matches our goal, we will define criteria such as horsepower, brand, size, material of the tips, etc.

Cable drill

Corded drills will always have higher power and speed than cordless drills, which is why we must preferred if you have to drill extremely hard materials, like those found in masonry work: bricks, granite, concrete …

The direct and constant feed produces more power. At first, one might think that when faced with the dilemma of choosing a drill, the first answer would be to opt for a corded drill, for the reasons explained. However, you must take into account the limitations of the corded drill.

The main, and perhaps the only, is that this type of drill bit can only be used in spaces where we have direct and constant access to a power source. Consequently, work carried out in the open field, in gardens or on certain terraces could not be carried out with this tool.

It is good to understand why corded drills develop less power than their wireless brothers. The power of a corded drill is given by the number of watts it can consume the tool. The higher this value, the greater the power. Typically, this range is between 500 and 1000 watts. At more watts, we will have a drill that is more powerful and robust in its physical aspect since it must have a gearbox (like cars) and bearings.

In conclusion, at this stage of the talk about choosing a drill, we can say that the great advantage of corded drills is their power, which can be chosen from different ranges, depending on the work to be done.

Cordless drill

The cordless drill develops its power according to the voltage supplied by the battery. Drills used in DIY jobs have rechargeable batteries that range between 9.6 and 18 volts, although exceptionally they can go up to 32 volts.

Great cordless drill quality, is of course the portability and the ability to work in any space, even if we don’t have a power source, if we’ve been proactive and charged the battery to the max.

If we have opted for a cordless drill, the most important criterion for your choice will always be the battery life that the battery can offer. Let’s talk a bit about the different types of drilling batteries, their features and performance.

Nickel Cadmium Ni-cd

It is a heavy battery, which needs to be loaded frequently and has a memory effect. This is installed with screws, which is ultimately impractical. The memory effect is a difficult problem to solve, if one has not taken the precaution of letting the battery fill completely during its first charge.

is battery typeAlthough they are heavy and complicated to install and disassemble, they offer a great autonomy, up to six hours of continuous work.

Lithium

Lightweight battery, which is fast recharge and has no memory effect. Although its weakness is its cost, and the autonomy time, in the best case does not exceed 4 hours, the possibility of transporting several can possibly solve these problems.

NiMH / metal hydride

Behind this strange name hides a heavy battery, with a memory effect. Although it offers autonomy of more than six hours, its weight is its great flaw. This can eventually make the exercise difficult to maneuver.

Once we have opted for one of the two options, we must consider the type of material with which we will work. Although, as we have already stated, hard materials justify the use of a corded drill, it is not always possible to use one due to the location where the work will be done.

It is at this point that we need to evaluate the types of bits we will be using for each task. The material of the drill bit and the shape of the drill bit should be chosen according to the material we are drilling. Let’s look at some cases.

Wood

Nail low carbon steel drill bit, can provide us good service on wooden surface. If the holes are large in diameter, use flat head drills, which incorporate a dagger-shaped tip that acts as a guide for drilling. The drilling in wood must be fast because friction produces high temperatures and the risk of fire is imminent.

Concrete stone and ceramic

Drill bits for these materials are usually made in high carbon steel and they are usually shaped like an arrow. These bits are made with high impact and heat resistant alloys to withstand pressure without weakening.

Metals

They are generally used HSS drills (HSS), in which there are four varieties: laminated, rectified, rectified titanium Yes rectified cobaltThe latter being those which exhibit the greatest resistance to temperature and to the hardness of materials.

¿How to choose a drill? We hope the problem is resolved. We will be back in this space soon, with topics of interest in the DIY world. See you next time.
