Metal Drill Bit Vs Wood Drill Bit See The Major Comparisons

If you’ve got many drill bits lying around, it might be challenging to figure out which ones are appropriate for particular materials. It might be difficult to tell the comparisons between a metal drill bit vs wood drill bit since many drill bits are multi-functional.

In some projects, you’ll have to use both drill bits. For example, those who build their boats from the ground up need to know the difference between metal and wood drill bits at some point, so familiarity with the two types of tools is essential.

We will discuss these two types of drill bits today and where they overlap, as certain drill bits may be used for both materials.

What is Metal Drill Bit

Using metal drill bits to make holes in metal surfaces is standard practice. When compared to wood drill bits, these are far stronger. Therefore, these drill bits may also be used to drill holes in wood. On the other hand, you should use caution while drilling into wood since you risk harming the object.

Metal Drill Bits

There are several metal drill bits to choose from. Among these, one is the focal point and focal point. This drill bit aims to indicate where you wish to drill. Metal drill bits with spiky heads are what they are called. As a result, labeling a particular work piece component becomes easier for you.

The Core drill bit is a different form from the metal drill bit. Drilling is made more accessible with the help of this drill bit’s two principal purposes. Creating an annular cross section while drilling a hole is one method while magnifying an existing hole is the second method used.

You also have drill bits that can be indexed. These drill bits are more costly than most other metal drill bits. There are two inserts in each of them. One insert should be placed inside the radius, while the other should be outside.

Kinds of Metal Drill

We’ll show you the market’s most popular varieties of metal drill bits.

Center Bits

Center bits have non-flexing shanks that are highly robust and thick, making them ideal for spot drilling. They are commonly used in lathes and drilling presses for high-speed drilling applications. Using center bits, it is possible to make exact pilot holes.

Twist Drill Bits

To identify a twist drill bit, look for its conical cutting tip and spiral flutes, which form the twist on the metal rod. Bits like this one are highly adaptable since they are powerful enough to pierce many materials like plastic, wood, concrete, steel, and more.

Step Drill Bits

A step drill bit has a cone-shaped tip with several diameters, making it a distinctive design. To produce multiple-sized holes or to widen existing holes, you can use a larger tip at the bottom of the drill. When drilling through thicker sheet metal, you’ll need something more robust than this drill bit.

High-speed steel Bits

Drill bits made of high-speed steel, often known as HSS, are widespread and may be used on virtually any material.

With the right size and materials, HSS drill bits may be used on various materials, from metal and plastic to wood and stone. For example, softwoods can be split using these bits, which do not have a bad point.

However, these drill bits are popular because they can easily cut through metal.

Coated High-speed steel Bits

There are several types of HSS bits, which are highly robust and widely used in metalworking. Carbon steel is used in construction, and a protective coating such as titanium or black oxide is used to provide further protection.

They can only use essential HSS bits on thin metal or aluminum, which is why they are so limited in their application. HSS bits with a more robust finish will need more durable materials.

What is Wood Drill Bit

As the name suggests, drilling holes in wood requires using a wood drill bit. This drill bit was designed to prevent splinters from being broken or the wood from being entirely ripped apart during the cutting process. Many wood drill bit types have been created to increase their capacities. Although these enormous changes may be challenging to comprehend, it is straightforward to learn about them.

Wood Drill Bit

Wood drill bits come in various shapes and sizes, enabling them to be used on a wide range of wood species. Drill bits with brad-points are pretty widespread in the woodworking industry. However, drilling with brad point bits may be tricky. Thus this tool helps to ensure that the bit is firmly in place before commencing.

There are a few wood drill bits, such as paddle bits or spade bits. Because of their size and power, they are the finest drills for large bores. Despite this, they can also leave behind a few bumps and bruises while drilling. Using a paddle bit with a wide-cutting function causes this.

Auger bits, installation bits, and Forstner bits are different kinds of wood drill bits.

Kinds of Wood Bit

Listed below are the most often encountered varieties of wood drill bits.


Bits for the tip and the Spur

The tip of this bit has a little spur, which allows it to drill into the wood without missing the mark or falling off the mark. Spiral-shaped, it’s perfect for drilling tiny holes with precision.

Bits of Spade

Spade drill bits are the best option if you need to make holes with huge diameters. They’re perfect for this type of job because of their flat form and wide-cutter design.

Bits for Auger

Next, we have an auger drill bit with a spiral body and a screw drill bit tip. This eliminates the need to apply additional pressure during drilling since it pulls the wood to the bit. Wooden things may be drilled through with this one.

What is the Difference Between a Metal Drill Bit vs Wood Drill Bit

Our discussion on wood-versus-metal drill bits has concluded, so we’re ready to move on.

Form and Style

To begin with, there is a distinct distinction between a wood drill bit and a metal drill bit. Drilling into wood is designed to retain the drill bit in the same place and in the same position.. It’s a common trait of all wood drilling bits.

On the other hand, a metal drill bit does not have a spur like this at the front. Instead, the cutting tip of a metal drill bit is conical, and the flutes that follow it are spiral-shaped. To put it simply, this is what sets each of these drill bits apart from the rest.


Although wood and metal drill bits may occasionally be constructed of the same material, metal drill bits need to be more challenging and denser to drill into a much thicker and hard substance. HSS, cobalt, or carbide are common materials for wood drill bits.

Metal drill bits are often crafted from these materials, but they have been given an extra layer of protection to make them longer lasting. To extend the life of metal drill bits, they are often coated with black oxide or titanium.

The Need for Power

As a result of the form of a wood drill bit and wood’s softness, less power is needed to pierce the wood than would be required with a metal drill bit. Just though metal is more challenging and denser, the design of the metal drill bit means that it takes considerably more effort to pierce the surface.

Maintaining a sense of equilibrium

The center spur on a wood drill bit is one of the most valuable features since it helps keep the drill bit centered. Keeping a hole centered and aligned when using a metal drill bit is challenging since it lacks a spur to guide the bit.

Production of Thermal Energy

Drilling into metal creates heat, necessitating these bits to be coated in an exceedingly complex and dense metal such as titanium or tungsten. Drilling into wood generates a fraction of the heat of steel.

The main focus

Of course, a wood drill bit’s primary function is to drill into wood, whereas a metal drill bit’s primary function is to prepare metal.

Bit Types

There are several types of wood and metal drill bits to select.

In terms of wood drill bits, you may choose from various brad point, spade, paddle, drill, and installer bits, as well as Forster and hole saw bits. In addition, twist drills, step drills, and center bits are all types of metal drill bits.

Why are the Metal and Wood Bit Difference Matter? 

You have no idea why it’s essential to use a specific type of drill bit on a particular material unless you’ve tried it.

Fundamentally, the problem with combining different drill bits is that there is a possibility of irreversible drill bit breakage or material damage during the drilling process. However, the drill bit may function perfectly in some instances.

While it looks the drill bit worked, the material you are working with may have been damaged or destroyed as a result of the drill bit.

In the end, you should avoid putting yourself in that situation if you can.

Drilling Wood with a Metal Bit

Drilling wood using a metal-specific drill bit will almost certainly result in splinters, cracks, or possibly a complete break in the wood.

Because metal tips can sustain far more force than wood tips, the power may be too much for certain people. It all depends on the wood you’re working with and the type of metal tip you’re using. Something to watch for at the very least.

Drilling into Metal with a Wood Drill Bit

When using a wood drill bit on metal, the drill bit is more likely to be damaged than the metal itself. Even so, you risk scuffing or otherwise damaging the metal.

If you try to drill into the metal with a wood drill bit, it may strip or break because it lacks the proper cutting edge or tip to create a clean cut through such a hard material.

You’ll be able to accomplish your job more quickly and increase the life of your drill bits by utilizing the proper drill bit.

What’s the Similar Factor of Both Drill

Despite their differences, wood and metal drill bits share a few fundamental characteristics.

Both are Drill Bits

Drill bits are, of course, the most obvious connection between these two objects. It’s possible to drill holes in wood and metal with the appropriate drill bits.

You Can use a Wide Range of Tools With Them

They may use them with various instruments, a commonality between metal and wood drill bits. Bits that may operate with multiple drill drivers and hammers, as well as milling machines and drill presses, are included. In terms of size, the specific bits you utilize will be determined by the device in question.

Both Come in a Variety of Forms

To save space, we’ll discuss the distinctions between wood drill bits and metal drill bits. However, one thing they have in common is that both types of drill bits may be used for various tasks.

Do Metal Drill Bits Work with Wood

Wood can be drilled using a metal drill bit. Because of this, it may be challenging to detect large-diameter twist drills that do not have a spur point. Splintering and a subpar finish are also likely outcomes. If you dig all the way to the bottom, you may find torn-out pieces of paper.

A wood bit will harm the cutting tip if used on metal, and vice versa. Depending on how thick the metal is, you can use a drill bit to make a few small holes in aluminum or other soft metals. But, on the other hand, the bit will quickly run out of power.

Do Wood Drill Bits Work with Metal

Using a wood drill bit to drill into the metal on either side is not an option. Because a wood drill bit is not hard enough to penetrate metal, it cannot be used to drill through the material.

When drilling into metal, you risk breaking the wood drill bit. As far as a wood drill bit’s narrow and pointed front spur is concerned, this is especially true. Metal drilling creates enormous quantities of heat, and wood drill bits aren’t built to withstand that.


How Can You Tell the Difference Between a Wood and Metal Drill Bit?

Drilling using a metal or wood drill bit is vastly dissimilar in terms of design.. While drilling, a spike in the center of the wood bit keeps it from slipping. Spiral blades precede conical cutting tips in the metal bit, which is a twist bit.

How Can You Tell a Metal Drill Bit?

In most cases, the black color of metal drill bits is an easy way to identify them. Tungsten carbide, cobalt, or titanium are additional common materials for these tools, which should be mentioned on the package if you’re purchasing new ones.


The main distinctions between wooden and metal drill bits have been discussed in this article. Knowing how to distinguish between different types of drill bits will allow us to select a suitable one for the job. We have complete instructions on changing a drill bit for additional information. Drilling soft materials require the use of wood drill bits. To prevent material tearing, they can be utilized at lower speeds.

Metal drill bits, on the other hand, are powerful, long-lasting, and intended for use on hard surfaces. SDS drill bits, for example, are compelling metal drill bits. It’s possible to utilize them with bricks or other construction materials. However, to avoid activating cleavage in soft textiles, avoid applying them on wood.
