Please! for making a big hole on your wall to hang your 20 KG painting, do not use a 5 volts Power Drill, as it will do not bring any good but will damage both of your wall and the device. In the same way, if you do not want your cupboard to get cracked up, do not use a 20 volts power drill to make simple drilling to knuckle up a nail.

We often get confused among options of what volt of Power Drill should we get, when we see so many varieties are available in the market, and we end up getting the wrong type of drill for us. As the performance of drill is directly related with the drill voltage, when we get our self the wrong type of drill and tend to pursue our task, we get a pretty much faulty outcome, which does not damage us economically but also psychologically as the efforts and time go all in vain. So, here I will try to focus on the relationship between voltage and performance of the device and what voltage should we get to have our task done.

What is Voltage?

Well before proceeding further, let me clear some basics about voltage. We often get confused about voltage as many of us do not know what this thing is actually. Voltage is the capacity of how much power an electric device can deliver while performing a task. The higher the voltage, the higher the capacity, similarly, the higher the voltage, the higher the price.

What is the voltage range available on the market?

The voltage is usually printed on the back of the machine. Usually, you will find devices with the range from 3 volts to 48 volts. I believe, from it, you can easily get the idea that, devices with 3 volts to 15 volts are usually for low involvement task and devices from 30 volts and onwards are aimed to do a very high-end task. So, when you tend to get one power drill for yourself, make your tasks and motives defined.

What is the relationship between voltage and high and low-end duty?

Well, just imagine a situation that you need to make a hole in the cupboard and a hole in the wall? Would you put an equal amount of efforts in both cases? Are all the procedures be the same? Nah In a similar way when you tend to perform such pro level works, such as professional plumbing and others, you will require a very high-density voltage power drill. But if you tend to do some simple DIY projects, such as making your hamster a simple play-box, you literally do not need the pro level of a device; as I already said, the higher the voltage, the higher the price. So, expending such amount for your simple drilling and driving project will be a complete wastage of your money.

What is the relationship between the voltage and speed?

Do you literally need a high-speed device which performs your duty at once? Then you get to choose something with a higher voltage! Then again keep the phrase in mind “the higher the price”, yes you read it all correct, you need your device to be very speedy, you need your device to perform the task very quickly, you need your credit card to get debited more.

Usually, volts ranges from 12-14 give you a considerably reasonable speed with price, if you compare with the higher volt ones.

How frequently would you like to use your device?

Well, using a device, again and again, requires some extra power infused in it. So, if you want to buy a device for a very long period, to use it over and over, it is always recommended to get a high-powered drill, volts range from 15-24. Well, yes, it will be a bit pricier, but if you consider the lengthy and frequency of usages, the cost totally worth it.

Do not consider a budgeted item for frequency purpose. Just think of a situation, you came up with a low-end drill, even say for simple DIY home décor projects, but after couples of use, the device gets broken! Will you really think that your money has brought the right value? Not at all. Hence, even if you tend to use the device, again and again, go for a higher range one, instead of a low budgeted one lesser capacity.

How much weight do you want to carry?

Well, the higher voltage devices tend to be very heavier, as the battery requires some extra space. Since the size of the battery gets bigger and heavier, the device tends to be weightier, which will create a little bit inconvenience while using the machine. So, if operating convenience is your prime concern, go get a lower voltage drill, such as 7-12 ranges’ volts, but if you find it convenient enough to carry a weighty product here and there, you can go for a better and higher ranges one.

If you want all the info on a single shot, I will say, remember one thing, that the higher the voltage, the higher the price. Now, what benefits bring a higher voltage device; it is speedier, it can perform any task more efficiently, it can be used again and again, it can last for a longer period, it can perform a very higher duty job; but top of all, it will make you spend some extra bucks and will add a little bit inconvenience. So, before choosing your device, consider all these positive and negative sides, and make your perfect decision.
