As everyone knows, there are many different kinds of drill types. Everyone knows the problem that can occur even with small jobs in the house. You want to hang up a wall cabinet or a mirror and you have to drill a hole in the wall provided. The choice of the right drill plays a crucial role here. Because not every one of these tools can be used on every surface. Because if the wrong drill is used, not only the tool itself can be damaged. If you want to know more about the kind of cordless drill and buying guides, you can check the article listing some of the best cordless drill you can find.
So that there is no disaster when drilling in your home, we present the most common types of drills and their areas of application in this content. There are also helpful tips on how to best use each drill. With this know-how, there is definitely no more frustration when drilling holes for any purpose.

Understanding drill types
Especially those who are not exactly talented do-it-yourselfers and who rarely grip with heavy equipment such as drills find it difficult to choose the right drill attachment. Because there are many different drills on the market that have their special areas of application. If you are not particularly knowledgeable, the wrong tool is quickly chosen.
The respective end result can then look fatal. Drill holes in the wood that are more like burn holes, or cracked tiles, are just two of the many problems that can arise when using the wrong drill. To avoid such a small disaster, it is important to use the right attachment for the drill.
Each of the different drills has special features that distinguish it. For soft materials such as wood, for example, those drills are used that have a distinctive tip. For tiles, in turn, there are specially hardened drills, which ensure that the tiles cannot be damaged as quickly during the drilling process.
The characteristics are very different and distinguish the respective drill. But there are also universal attachments that are suitable for several areas of application. In the following, we go into the most important variants in more detail so that everything runs smoothly when drilling.
The different types of drill
As already mentioned, each drill version has its own characteristics that make it unique. In this section, we go into more detail on these, so that confusion is almost impossible and the choice is easier.
Stone and concrete drills
The stone and concrete drills are primarily used when working with solid rock types. Since it is very difficult to cut through this material, more is ground and broken up here. These drills are particularly suitable for granite, marble or concrete.
In order not only to protect the drill but also to make the work a lot easier, an impact drill should be used, especially for the hard stone types. This works like a kind of electric hammer, which takes turns in quick, brief strokes while drilling and at the same time grinds into the ground. It is easy to drill holes in this material within a very short time.
If there are several or deeper holes, sufficient cooling of the drill should be ensured. As a result, it does not overheat so quickly and the work can be carried out better. To ensure cooling, either a special drilling paste or some kind of lubricant can be used.
Alternatively, regular short drilling breaks allow the respective drill to cool down. The stone drill can even be used for tiles. However, a certain amount of experience is necessary to avoid causing damage to the material. The right speed is crucial for all materials in this area. For drilling in stone and concrete, and especially for tiles, choose a low speed. This protects material and tools.
Features stone and concrete drill
The stone and concrete drills have a rather wedge-shaped tip, which is ideal for drilling in natural stone, granite, tiles or concrete. The hardest variant consists of carbon steel. A small hard metal plate is soldered onto the wedge-shaped tip so that the drill can get through the hard rock without any major problems. This is particularly resistant, which makes working with hard material much easier.
Since this drill does not actually cut like the others, but rather smashes it, stone drills are more likely to be used in an impact drill for harder materials. There is also a spiral here that carries the dust out of the borehole.
Wood and Traditional Drills
It is not easy to drill into a soft material like wood. If the wrong drill is used, the holes will either tear out or even burn. But even with the right drill, there are a few things to consider. Especially with very soft wood such as spruce or pine, it can be difficult to drill clean holes. It is also important to ensure that the attachment tip is positioned at the correct point. Because readjustment is then no longer possible.
A sharp drill must always be used to ensure that the drill holes work properly. Otherwise, the holes tear out as well. A medium-speed also ensures that there are no marks or burns on the wood. The drill should also be driven slowly into the material, otherwise the spiral can clog quickly.
Features of wood and traditional drills
Wood drills are mostly made of high quality but softer tool steel. This allows effortless drilling in both hardwood and hardwood. Particleboards or MDF boards are also not a problem. Each wood drill has an attachment tip that enables precise alignment.
Due to the fine tip, the wood drill cannot slip during work. Due to the sharp cutting edges, the holes in the soft material cannot fray. There is also a spiral on the shaft that transports the fine wood dust out of the borehole.
Special drills for special areas of application
So far we have revealed everything important about the most commonly used drills. But apart from the twist drills, there are still some special variants that differ greatly in shape and structure from the twist drills. This is usually referred to as special drills. These usually have very special areas of application for which they were built. Additional areas of application are usually not provided.
The special drills are mainly used in the professional, commercial sector. These special designs include, for example
- Cordless drill,
- Cordless impact driver: Impact drivers allow for the driving and loosening of the most obstinate fasteners. In addition, they are more compact and more lightweight than traditional drills. See best cordless impact driver reviews
- Cordless impact wrench or
- Sheet metal peeling drill.
As the names suggest, the special models are rarely used in private areas. Hobby DIY enthusiasts, in particular, should limit themselves to the use of the usual twist drills. Because working on glass, for example, should anyway be carried out by a specialist company due to the high risk of breakage.
Note: Special drills should rather be used by experts. Since the application and handling can be complicated at times, these drills are more suitable for commercial use.
- Use only the appropriate drill bit for the appropriate material
- The drill types can be identified by special features
- Universal drills are no alternative to the special types of drills
- Cutting edges can also be sharpened
- Material and drill can be spared at the right speed
