One certain thing, whether you are a DIY hobbyist, professional woodworker, or contractor that deals with power drills a lot, is that you need to have the best drill bits in your tools arsenal.

Drill bits are vital for drilling into different materials from wood and metals to plastics, stones, and concrete, which means they will be useful for a wide variety of professions.

The good news is that there are all kinds of drill bits out there, and you only need to know which ones will work for your particular projects. Here we review 10 best-rated drill bits and explain a few important points to keep in mind when shopping.

What To Check Before Buying Drill Bits?

How to Buy the Best Drill Bit

Here are some of the important things that you need to consider when shopping for the best drill bit set.

1. Drill Bit Type

The first and perhaps most important factor that you will need to consider when shopping for drill bits is the application.

And this is because drill bits are made for different uses. For example a drill bit made for wood will not be very useful for drilling concrete.

Here is a breakdown of the different drill types based on their applications.

– For Concrete

Concrete is one of the hardest materials that you can drill into. Hence, when shopping for drill bits for drilling in concrete, you need to make sure that they are up to the task and are also hard enough.

For drilling concrete, you will need the specialized masonry drill bits like the DeWalt DW5207. These drill bits have a steel body and will typically be carbide tipped to ensure they are strong and durable enough to drill through concrete.

Besides concrete, masonry drill bits are also ideal for drilling through other tough materials like bricks, blocks and stones.

– For Wood

Drill bits for wood are some of the most common ones in the market, and so you can be sure that there are plenty of option to pick from when shopping for a set.

In most cases, they are made from a high speed steel and will have either a titanium or black oxide coating to make them even tougher for drilling through even the harder wood types.

Wood drill bits like Black & Decker 15557 will also have larger and better flutes to make it easy to remove chips, and to ensure they can drill without clogging.

When it comes to the shape, any drill bit with flat wood, twist or even the auger bits will be ideal for drilling through wood. What you choose will depend on the shape of the hole you want.

– For Metal

Like concrete, metal is a tough material that will require a tough drill bit to drill through it.

The best metal drill bits are often those made from cobalt like Bosch Cobalt Drill Bit. Cobalt is a tough material that can drill through almost any kind of metal with ease.

Unlike drill bits for wood that have a sharp tip, the metal drill bits have a flatter and blunt tip as it is more effective on the harder surface.

But, it is important to always make sure that you lubricate the metal adequately when drilling to ensure the heat generated from friction does not damage the bit.

2. Drill Bit Material

The material used to make the drill bits also matters as it determines whether it will be hard enough for the intended applications and also determines its durability. Here, the most common material options are.

– Low and High Carbon Steel

Low and high carbon steel are some of the most common drill bit materials. The low carbon drill bits are softer and tend to be more affordable, but they will not stay sharp very long. Hence, they will be typically used for drilling wood only.

High carbon steel drill bits, on the other hand, are more durable and can cut both wood and metal with ease, which makes them a little more popular than the low carbon steel types.


High speed steel is perhaps the most preferred drill bit material, and it will often be the core material for the black oxide and titanium-coated drill bits.

The HSS drill bits are also made from carbon steel, but with vanadium or chrome also added on to make them even tougher and to allow them to be used for high speed drilling.

These drill bits also have a higher heat-resistant and will be perfect for drilling both metals and hardwoods.

– Titanium

Titanium drill bits are often just high speed steel bits with a titanium coating. These bits will produce less friction and are typically tougher than the regular HSS bits.

Many users also love the fact that they maintain the sharp edge much longer. Titanium drill bits like DeWalt DW1361 work best when drilling non-ferrous metals, PVC, fiberglass and wood.

– Cobalt

Cobalt drill bits are still a type of high speed steel, but with more cobalt in its composition. This allows them to stay harder even when drilling at higher temperatures.

But, these bits tend to be more brittle than the regular HSS ones. However, they are perfect when drilling hard materials like stainless steel and aluminum as they will also dissipate heat faster.

– Zirconium Coating

The zirconium coated drill bits are famous for their golden color.

For these drill bits, zirconium nitride is used to coat hard but brittle steel material to make the bits harder and allow them to withstand relatively higher temperatures.

3. Drill Bit Shank

A drill bit shank is the end that will fit into your drill, where it is then secured by the chuck. Hence, as you shop for a high-quality drill bit, you will need to keep the shank in mind to ensure what you get can work with the tool you have.

Besides ensuring that the shank will be ideal for your tool, it should help improve the overall performance of the bit. For example, the no-spin shanks on the DeWalt DW1354 help ensure that your bits will not slip when drilling.

Also, make sure the shank size does not exceed the size of the chuck on your drill and the shape should be appropriate. A round shank makes it easy to center the bit on the chuck accurately, while the hex shank will allow the drill to grip the bit more securely.
