Types Of Drill Bits
What are the different drill bit types? Drill bits are classified, considering the material that will be drilled with them.
For each surface, it will be necessary to use a suitable bit capable of easily making a hole in it.
In the market, you will find different types, and we show you which are the most common so that you know how to choose the right one.
The Concrete Or Masonry Drill Bit
A stone drill bit is also called a concrete or masonry drill bit.
This drill bit has a reinforcement on its head to resemble a shovel.
They are the type of drill bits most used in work and construction since they are the ones that allow us to drill holes in all kinds of walls and construction materials such as concrete, brick, etc.
They are only suitable for a hammer drill, requiring a hammer function to work correctly.
Thanks to this, it can make holes in very hard materials and, at the same time, increase its durability.

What Are The Types Of Concrete Drill Bit
Widia Drill Bit
They have a high hardness and are ideal for drilling hard materials such as marble.
Tungsten Carbide Drill Bit
The laminated body of the Tungsten Carbide Drill Bit can drill hard materials like granite, concrete, marble, and brick.
The bit is manufactured with tungsten carbide, a material with incredible properties such as hardness and resistance.
In addition, they are also a very versatile type of drill bits since they can also be used on other materials such as metal, plaster, or cardboard.
Carbide Milled drill bit
The Carbide Milled drill bit body is milled, and its durability and precision are greater than that of the Widia drill bit.
It is suitable for drilling plaster, cement, limestone, brick, sandstone, and uralite.
They are manufactured with tungsten carbide, a material with incredible properties such as hardness and resistance.
In addition, they are also a very versatile type of drill bits since they can also be used on other materials such as metal, plaster, or cardboard.
How To Identify A Stone Bit
We can identify a stone bit by its pointed tips that look like a carbide or diamond and are made of metal.
Masonry drill bits are usually made of chrome-nickel-molybdenum or tool steel.

At the top, there is a hard metal plate that is very durable.
When impact drilling, this plate ensures that the material is broken up in small steps and transported out of the lock by the drill auger.
How To Use A Concrete Bit
When drilling hard materials, such as walls, we will need a drill bit for concrete, solid brick, or stone to create holes safely and optimally.
To do this, we will need masonry drill bits that will help us achieve our goals.
The qualities of these devices are undoubtedly hardness and resistance.
In many cases, such a drill is used for impact drilling, as normal rotary drilling in concrete, for example, is inefficient and sometimes hopeless.

This tip can be either ground or unground. When unpolished, the drill suits concrete, stone, and masonry.
We used The ground version without the hammer drill function. It is suitable for granite, perforated brick, or tiles (although a dedicated tile drill would be advantageous here).

Such masonry drills are often equipped with a special SDS system. I have already written about it. Clamping and changing drills 👉click here to read. 👈[Link ]
You can recognize it by the three notches that the drill has on the underside and cannot be inserted into a “normal” drill chuck.
The Wood Drill Bit
Wood drill bits are the most common and easiest to differentiate. Their specifications make them ideal for working on wooden surfaces.

What Are The Types Of Wood Drill Bits
All types of wood drill bits have in common that they have a very sharp and pointed tip to be able to do highly precise work.
Do you want to know how a drill bit looks? I have an article showing you how to identify a drill bit and how they look 👉click here now to read.[Link]
However, many types within this category will suit very specific jobs.
Three-Pointed Wood Drill Bit
They are the most used drill bits for drilling wood. They are usually made of chrome-vanadium steel. They are used in drilling all types of wood.
They are drill bits designed to drill wood so that they have 3 points in the head.
One point in the center to center the drill bit and two on the sides responsible for cutting the wood to leave a perfect hole.
These bits are used for drilling all types of wood: hard, soft, chipboard, plywood, etc.
You can find varied lengths and diameters.
Forstner Drill Bit
These bits make clean, circular cuts and remove debris very efficiently.
They can create holes even in the hardest woods, and their precision is very high.

Twist Drill Bits
It can be said that twist drill bits are the most widespread when drilling wood.
This type of cut is focused on creating holes by eliminating excess wood. They are very precise, resistant, and functional.
They have a very sharp propeller and are quite dynamic.
Crown Drill Bits
Crown drill bits, or C drill bits, are used to produce large-diameter holes.
Its shape differs from other drill bits because it has a toothed crown with a guide drill bit (normally) inside and generates a circular saw effect when drilling the wood.
Paddle Or Spade Drill Bit
The paddle drill bit, also known as a sword drill bit., Spade or flat drill bit, can open holes of different diameters through a drill or even with a drill bit.
It has a very sharp tip that is used to stick it superficially into the wood and serves as a guide to create the drilling precisely.
The length is usually not too long, but it is very useful for creating holes in all carpentry and construction work types.
It is also known as a sword drill bit.
Router Bits
Finally, it is worth talking about router or router bits.
These types can generate formats and holes of different shapes and sizes.
They are mainly used in cabinetmaking, and one of their uses is to create spaces to assemble pieces of wood.
Router bits I also used to create designs on a wood plank and can be used to make a perfect circle when working with wood.

How To Identify A Wood Drill Bit
A wood drill bit has a head with three very sharp points. The sharp, pointed mouth is tiny than the whole body.
The one in the middle is the key to differentiating it from other types of drill bits since it is the guide that helps make the hole clean and precise.
It has a centering tip at the front end. With this, you can place the drill exactly in the center of the hole to be drilled.
Wood drills also have two sharp cutting edges. These are longer on the outside than on the inside.
This way, you get a good result after drilling (first cut the hole and then cut through the fibers) without fraying the wood.
In terms of material, such a wood drill usually consists of tool, carbon, or chrome vanadium steel.

How To Use A Wood Drill Bit
You can drill wood materials with a wood bit. It is completely unsuitable for other, harder materials.
Similar to a small needle, the centering tip described above means you can always position the drill securely.
If you don’t drill well, your bit may break, so read how to remove a broken bit 👉 click here to read now👈[Link]
That is also important. While with other drillings (concrete, brick, etc.), it is often not important where exactly the drilling hole is; wood can undoubtedly play an important role.
Wood drills are designed to be clamped in both normal drill chucks and keyless chucks.

However, I don’t know of an SDS drill for wood. Wood drills are also very popular in pillar drills because they allow you to drill precisely.
The Metal Drill Bit Or HSS Drill Bit
Metal drill bits, also called HSS drill bits, are used for drilling in all types of metals, such as iron, steel, stainless steel, aluminum, or sheet metal.
These HSS drill bits are the most common type for industrial work since metal drilling is a very common task.
However, drilling sheet metal is not the same as making holes in steel.
Within metal drill bits, we can classify them into different types depending on the quality of the manufacturing materials and the cutting capacity:

What Are The Types Of Metal Drill Bit
Rolled Hss Drill Bits (Hss-R)
Rolled HSS drill bits are the most straightforward and economical metal.
They are drill bits that offer little durability since they easily lose their sharpness. And are only used in situations where precision in drilling is not required.
Also, learn how to drill a steel material 👉by clicking here.👈[link]
Ground Hss Drill Bits (Hss-G)
Ground HSS drill bits are mid-range metal drill bits.
Although they are more precise and of higher quality than laminated ones, they usually do not offer great durability either.
They are drill bits suitable for drilling all types of semi-hard materials up to 80kg/mm2.
Titanium Hss Drill Bits (Hss-Tin)
HSS-Tin titanium drill bits are metal drill bits coated with a titanium alloy, which allows drilling in all types of metals, including hard metals that are difficult to drill, such as stainless steel.
These titanium drill bits offer maximum precision and long life.
Note that these titanium drill bits can be used in high-production machines but require cooling.
Rectified HSS Cobalt Drill Bits.
They are the highest quality drill bits for drilling metal. They can drill even the hardest metals and stainless steel.
They are highly precise and durable drill bits that do not require cooling as they resist high temperatures. Therefore, they can be used at high cutting speeds.
Focused on the construction and industrial sectors, they can drill alloy steels and all types of metals regardless of their hardness.
They are very resistant and usually have a great chip evacuation capacity, essential for achieving homogeneous drilling.
How Can I Identify A Metal Drill Bit
The tip of such drills usually converges in a cone shape. It has two cutting edges, both of which are sharpened.
These have a sharp conical end capable of piercing metallic materials and two helical channels.
You must spin at a higher speed to drill metal, especially when the hole is smaller.
HSS is usually used as the material. This is the abbreviation for “High-Speed Steel.”
These have a high level of hardness and high wear resistance and are particularly tough.
However, it must be said that when it comes to metal drills, there are also many different types, depending on the metal, stainless steel, steel, aluminum, etc., you intend to work with.
A distinction is made here specifically concerning the additional coating (titanium nitride, cobalt, etc.).
How To Work With A Metal Drill Bit
Cutting metals can be one of the most delicate matters, especially if you want to drill through particularly hard steel.
Unlike drilling wood or concrete, drilling metal generates a lot of heat. You, therefore, have to pay particular attention to two things:
Firstly, the speed is adjusted and not too high; secondly, cooling fluids are available, usually drilling oil.

If you don’t pay attention to this, the drill head can burn up quickly and then it is broken.
It can be seen from the blue discoloration of the drill tip. And if you think this will take time – it won’t.
Too much pressure, too high a speed, and hard material, and the drill can burn up within seconds!

The Universal Drill Bit
The universal drilling beat is one of the Types of bit we have.
There are many different drills, so it’s no surprise that there is one that can do (almost) everything, namely the universal drill bit.
Multipurpose, universal, or multi-construction drill bits are those that can drill different materials.
They are usually chosen by those who want to have materials for sporadic use, such as small home repairs or homemade DIY jobs.
Without a doubt, these are drill bits with great versatility.
They drill the materials by cutting and do not use a hammer.
The same drill bit can be capable of drilling bricks, wood, metal, or ceramics, among others.
It is a great option for small arrangements or needs.
However, their use is not recommended for professionals since multipurpose drill bits are used sporadically and not frequently.
As is the case with people dedicated to cabinetmaking or construction.

How To Identify Universal Drill Bits
Its tip usually converges in a wedge shape and is made of hard metal.
It has two sharp cutting edges and is made of HSS steel (see metal drill) or tool steel.
How To Use the University Drill Bit
In my opinion, universal drills are overrated. Yes, they can drill different materials, but none, as well as the special drills.
At least that’s my experience, or I chose the wrong products.
However, these drills are quite acceptable if you want to drill into walls or ceilings with different building materials and don’t want to change the drill whenever you come across a new material layer.
For example, if you are drilling tiles, you can use its sharp cutting edges and drill through concrete and brick with the hammer drill function.

The use of unclamping and clamping works in the same way as with other drills.
Diamond Bit
Diamond bits are used for drilling in ceramics, porcelain tiles, and other coating materials.
Although the basis of diamond drill bits is always their diamond-coated end, these drill bits are also available in different types and models that differ in:
1] Models for wet or dry drilling.
2] The quality and quantity of diamonds, as with diamond cutting discs, will determine the quality and effectiveness of the drill bit.
3] Type of drill shank, since, as you can see, there are models with a round or hexagonal shank to adapt to a drill and models with metric 14 to adapt to a grinder.
Glass Drill Bit.
Both glass and crystal are very sensitive materials to any impact or vibration.
That is why it is necessary to use a specific glass drill bit if we do not want to break this material into a thousand pieces.
In general, they are wet cutting bits; they need continuous cooling to avoid damaging the material.
In addition, they are manufactured by electroplating, which means they transmit a few vibrations to the material.
The head has a shaft, like the tip of an arrow, and allows access to the material precisely and safely.
How Do You Choose The Right Drill Bit?
Once we know the different types of most common drill bits, we are going to briefly comment on the steps to follow in choosing the right drill bit and being able to make the desired holes efficiently:
1] Know the material you want to drill and the diameter of the hole
I will say It is important to know the type of material you will drill and to choose the appropriate drill bit.
It is also very important to know the hole diameter you want to make, as this will influence the drill bit size you need.
2] Select the Type of drill bit for the material:
As we have seen, a wide variety of drill bits are designed to drill a specific type of material.
Each type of drill bit will be more effective for a certain type of material.
Make sure you select the right drill bit for the material you are drilling. I love this aspect so much.
3] Choose a drill bit of the necessary quality and the appropriate diameter:
Once you have selected the appropriate Type of drill bit, it is important to choose quality and the appropriate diameter for the task you will perform.
Quality drill bits will last longer and make more precise holes. Also, choose the drill bit diameter to achieve the hole size you need.
4] Proceed to make the hole with the appropriate tool for the drilling to be done:
Lastly, to say, you must ensure that you use the appropriate tool for the drilling you need.
This includes choosing the right drill with the speed and power needed for the task.
A good professional drill will be very important, especially if we have to make many holes.

FAQ
Can I Use One Drill Bit For Everything
No, You can hardly use one drill bit for every material. This is because different materials differ significantly in their strength and composition.
Drill bites are made with different materials and different strengths; all materials are different. For example, stone is harder than wood.
For example, A stone drill bit cannot be used for wood except apply some hack like me.

Why Can’t I Use A Single Drill Bit For Every Material?
You can’t use a single drill bit for every material because materials vary in density, characteristics, and hardness. Hence, we need a specific drill bit for optimal results.
I will require a different bit for the following reasons:
1] The drill bit split point; not all bits require a pointed edge penetrating a specific material.
For example, wood requires a sharp point to pass through, which is why metal and concrete do not.
If you don’t know what A stone or concrete bit looks like, click here to read. [Link]
2] The bit body structure: some materials require a twist, step-step bit to penetrate through them, the other does not.
I have covered the full guide on how to use a step drill bit. Are you interested? Click here to read.[Link]
3] Drill Bit Material: drill bits are made of different metal strengths that suit a particular material’s specific needs.
For example, HSS means high-speed steel suitable for wood and light materials.
While carbide or cobalt bits are specifically made to penetrate through harder metals and masonry.
Also, read what the HSS bit is all about. Click here to read. [Link]
4] Heat and Friction: when drilling, we generate heat and friction between our drilling bit and the workpiece.
Lighter materials like plastic can melt when drilling at high speed. Still, we prevent the material from being damaged using the right drilling bits.
Hard materials like metal also generate heat when drilling. The heat generated during drilling can damage poor steel.
Ensure the right bit for each material.
Conclusion
What are the different drill bit types? As we have been able to verify, choosing a specific type of drill bit is important to achieve good results.
Know that every drill bit has its work to perform on individual materials because not all bit is designed the same way, and not all material has the same hardness.
