Whether you work at home in the garage or as a full-time craftsman, everyone can quickly find a suitable drill bit set here.

With our drill bit set test 2021, we want to help you choose your next drill bit set. We have compared a wide range of different drill bits to recommend professional quality drill bits. No matter what project you have in mind, with our guide you will find the right drill set for every craft challenge.




Summary

  • Drill sets offer you the possibility to work on a wide range of materials. When buying, you should look for your own individual requirements.
  • Your ideal drill set should support you extensively in your work with an appropriate selection and quality.
  • Before buying, think about what you expect from the tool; a professional differs enormously from a do-it-yourselfer. The more versatile and resilient your drill set should be, the higher the price will be in the end.

The Best Drill Set: Our Choices

Buying and evaluation criteria for drill sets

In the following paragraph you will find out which criteria are important when buying a new drill set.

Our most important buying criteria when it comes to drill sets at a glance:

In the following paragraphs you will learn more about the individual criteria in detail.

Scope of the drill set

The size of the drill set refers to the number of inserts that are included in your set. The larger the set, the more choice you have when drilling. Also look at how the drill bits vary in size and suitability within the set. The range of sizes is very wide, but you can also buy sets with as few as 5 drill bits.

For larger sets, we recommend that you keep a well-organised box. This way, your drills will always be organised and ready for use.

Drill diameter

The drill diameter of the inserts indicates how large holes you can drill.

It is helpful if you think about where you want to use the drill bits. Smaller diameters are usually sufficient for drilling holes in the house or flat. For outdoor work, it is usually advisable to use thicker drills.

Common drill sizes range from 1 to 10 millimetres.

Material suitability

This is about the material for which you should use the drill.

Always try to ensure that you use a suitable drill for your work to minimise wear and tear.

Each drill is best suited to work with materials of a certain hardness because of the material it is made of. Therefore, it is important to think about the materials you want to work with. You can imagine that a drill for soft wood must have different properties than a solid concrete drill.

In the next section we will go into detail about the different types of drills.

Load capacity

The load capacity describes the general life span of the drill bit, you could also call it quality. In general, it is recommended to pay attention to the experience reports of customers and experts. They will usually tell you honestly how long the set has lasted for them.

We would like to point out that it is not necessarily the highest price that counts. Rather, it means that you know best how much you intend to use the drill. For more complex construction activities, we recommend that you think about the load capacity of the drill set when buying it.

Decision: What types of drill sets are there and which is the right one for you?

Drill sets are most likely to be differentiated by their areas of application. Here you will find a compact overview of the most common classifications.

Type Advantages Disadvantages
Wood drill Suitable for any wood Wood can fray due to different hardness
Metal drill Ideally suited for metals and plastics Can anneal at the tip
Concrete drill Resistant tip for very hard material Unsuitable for metals or wood
Multi-purpose drill Suitable for any material Often comparatively high price

In the following section, we want to help you choose the right drill set for you. To make your decision easier, we will go into detail about the advantages and disadvantages of the different types of drill bits.

Wood drill

Wood drill

Wood drills are designed to work with any type of wood. If you intend to drill holes in wood, this is the best option. In addition, you can resharpen wooden drills much more easily yourself compared to the following, harder drills.

But you should also be careful that you do not try to drill harder materials than wood. This can quickly make the bit unusable.

You should also be aware that wood, as a naturally grown material, can always be of varying hardness. This can quickly lead to fraying when drilling.

Advantages
  • Suitable for any type of wood
  • Easy to sharpen yourself
Disadvantages
  • Unsuitable for hard materials
  • wood can be damaged
Metal drill

Metal drill

The metal drill is ideal for you if you want to work with a wide range of metals and plastics. Whether you want to drill iron, copper, steel or aluminium, this drill should be your choice for all metals and plastics.

However, you should note that the drill is much less suitable for all other materials such as stone or wood. In addition, the drill can anneal under excessive load.

Advantages
  • Suitable for metals
  • Suitable for plastics
Disadvantages
  • May anneal
  • Not suitable for wood
  • Not suitable for concrete
Concrete drill

Concrete drill

Concrete drills allow you to drill holes in some of the hardest building materials. So if you are planning to work on concrete, stone or granite, you should take a closer look at these drills. In addition, due to the requirements, these drills are very durable and have a long service life.

You should be careful when drilling softer materials, as concrete drills are completely unsuitable for such tasks. This can go so far that the concrete drill damages your material.

Advantages
  • Suitable for concrete and stone
  • Resistant tip
  • Low wear rate
Disadvantages
  • Not suitable for soft materials
Multi-purpose drill

Multi-purpose drill

The multi-purpose drill is the all-rounder in the drill family. With it, you should be able to work on any of the materials mentioned above. This saves you having to change drill bits when working with materials of different hardnesses.

Nevertheless, you should not think that the special drills have become superfluous because of the multi-purpose drill. Especially if you work mainly with only one group of materials, the special drills usually deliver a better result. In addition, the complex production of multipurpose drills leads to a comparatively higher price.

Advantages
  • Suitable for many materials
  • High resistance
Disadvantages
  • Comparatively expensive

Guide: Frequently asked questions about drill sets answered in detail

Here you will find answers to the most frequently asked questions about drill sets.

Which drill set is most suitable for you?

Which set is most suitable for you depends on the material you want to work with. You should always bear this in mind when making your purchase decision. Most drill sets can be divided into these categories based on their suitability:

  • Concrete and stone drill bits
  • Metal drill
  • Wood drill
  • Multi-purpose drill

Stone and concrete are particularly robust materials, which also require a very resistant drill bit. These so-called concrete drills are most elaborately ground and sharpened. This is to enable smooth material processing with a durable tool.

Twist drills are particularly suitable because they prevent the drill from jamming in the material.

Metal drills are intended for a wide variety of metals, which are in most cases much softer than stone. Therefore, this drill is less stable. It is best suited for drilling holes in metals or sheet metal.

For very soft materials such as wood or plastic, the wood drill is excellent. These have a much lower resistance than concrete or iron, which is why a particularly hard drill is not needed.

Multipurpose drills, also called universal drills, have established themselves as the fourth variant. These are supposed to make it possible to work on all materials with only one drill.

What does a drill set cost?

The price of individual drill sets can vary considerably. It depends on various factors, such as the scope of the set, the intended material or the brand. In any case, the price should not be your main reason for buying.

Price range for drill sets:

Price range price
Cheap from €10 - €20
Medium from €20 - €50
Expensive from €50 upwards

What do HSS and SDS mean for drills?

In the context of drills, HSS stands for "High Speed Steel". This special tool steel has been used for some time for the production of drill bits. Due to its advantageous properties, it has almost replaced conventional tool steel in drilling technology.

SDS refers to a special plug-in connection which stands for "Special Direct System". This enables you to change drill bits more easily.

Do you really need the professional drill set?

It doesn't always have to be the professional set, and not every set advertised in this way is actually a professional set. Think about what you want from your drill bits Professional craftsmen will have a different standard for their tools than hobby DIYers.

In most cases, manufacturers offer different drill sets for their clientele, so look around or ask for advice in your local shop.

Many large manufacturers have split their range to better suit the needs of DIY enthusiasts and professionals.

How long do drills stay sharp?

This depends on how you use and care for your drill bits. Be careful not to leave them in the dirt, and cleaning them occasionally will help them last longer and keep their edges sharper. You should also only use the drill for the material it is intended for.

The type of drill can also be decisive here. As already mentioned, concrete drills and drills for hard materials usually remain sharp longer.

Bohrer Set-3

A sharp drill bit is the basic requirement for gentle drilling. Try to keep your drill as sharp as possible, you can do this with a little care.

Can drills be sharpened again?

Only to a limited extent! Wooden drills are the most suitable for resharpening on your own. All other drills require a certain expertise about the object and the differences that need to be taken into account. If in doubt, ask at a specialist shop.
