We welcome you back to another DIY-post! 🧑🔧 Today we’re going to talk about types of power-drills. We’ll just assume that we all know what a power-drill is and what it’s for. So let’s go straight to identifying the different types.
Here we go!
Types of power-drills
Corded electric power-drill
As its name suggests, this type of drill requires a power supply connection for its use. Our first thought might be that this is a disadvantage since it forces us to stay close to a main socket or carry an extension cord, both there’s a reason for this. The advantage of a corded power-drill over a battery-powered one is that it offers a more stable and constant performance. For larger jobs, a battery-powered drill can have a poorer performance, or, in worst cases, it could leave us stranded when it’s less convenient. This doesn’t happen with an electric drill.
We have just mentioned it. This is a cordless drill powered by a battery. Since it is a portable drill we’ll enjoy the added convenience of being able to take it with us wherever we need. This is, as long as we remember to charge it and/or carry an extra battery to cover ourselfs in case of emergencies.
Electro-pneumatic or pneumatic drill
The electro-pneumatic or pneumatic drill is also known as “air-drill” (from the Latin pneumaticus ‘related to air’). This power-drill is driven by compressed air. It is a highly efficient and low maintenance drill. It can be used at workshops or for industrial jobs. Furthermore, it can be applied for drilling through walls and other hard hard materials such as concrete, flores, tiles, etc.
Technically, this is not what comes to mind when we think of a drill. But it does belong to the same family. This tool helps you screw and unscrew materials such as wood or metal. If you ever have to assemble or dismantle Ikea furniture, the power screwdriver is your best ally 😏
The main function of a hammer drill is the percussion act, meaning, that besides from a rotation it performs a small hammering that eases the drilling job. This is the tool you’ll want if you need to drill hard surfaces such as concrete, walls, floors, etcetera.
What should you bear in mind when buying a drill?
Before you buy a power drill, we’d recommend you ask yourself three simple questions:
Corded vs. Battery. Do you need a corded drill or is a battery powered-drill just as good?
Remember that a corded drill will allow you to work for unlimited time and at a higher power. On the other hand, if you need to be mobile or you’re looking for a drill for occasional jobs, you will be fine with a cordless drill.
Power. How intense is the job (jobs) that you are planning to do?
Keep in mind that the power of a drill is the equivalent to its working capacity. For heavy workloads, you will need more power. The power of a drill will be indicated in watts (W) if it’s corded and in volts (V) if it’s battery-powered.
Speed. Will you need a single or multiple speeds?
Single-speed drills provide stable work, while multispeed drills allow you to adjust the intensity manually. Slower speeds allow you to work harder, while faster speeds will, that’s right: increase your work speed. Within these options, the “electronic” drill is the most advanced type, since the adjective “electronic” refers to the electronic speed control, meaning, the rotation speed of the drill can be adjusted by means of a switch.
Having said all this, we hope to have shed some light on certain doubts regarding the types of drills.
We know that buying a DIY tool can be tricky if some basic concepts are not clear. There really isn’t one type of drill better than another, it all comes down to choosing the right one depending on your specific needs!

See you then!
