Can Any Drill Bit Be Used for Metal?

As much as we would like to use our favorite drill bit for everything, it will not always work for metals too. You need a heavy-duty drill bit for drilling metals as they can withstand all the resistance that metals offer. 

They have to be strong enough to resist the wear and tear that they will have to face. And not all drill bits can do that. So, you need specific ones for drilling into metals. 

Cobalt and titanium are the most commonly used drill bits for metal. Both of them are super-hard, and they do not corrode easily. This makes them ideal for drilling into hard and heavy metals. 

Characteristics of Our Favorite Drill Bits

Drill bits come with different features, and they have a signature design based on their manufacturer. Some of them have distinguished themselves with their characteristics. Here is what makes them our favorite. 

Shank Design

The shank design of our favorite drill bits is not the same, always. Rather, it depends on how well the shank design suits the purpose for which a drill bit is used. Some shank designs increase speed; some minimize resistance while some even purposefully slow down the drill. So, the best shank design is the one that meets the requirements of its users the best.

Hardness

We love hard drill bits the most as they can drill into metals perfectly. Metals are naturally hard and heavy, so they need something strong enough to penetrate their layers. This is why we like those drill bits which are hard enough to serve their purpose. 

Wear Resistance

Wear resistance is one of the most highly valued characteristics of our favorite drill bits. It makes sure that the drill bits stay fully functional even after constant usage. Products that are corrosion resistant and stay sharp impress us the most.

Warranty

The warranty of drill bits is also very important as it wins over the trust of buyers. When people know that their money is going into something trustworthy, they will be happier to invest in it.

After analyzing the reviews by recent users, we can say that it is most useful for home users. No matter if you are renovating your whole house or working on your garage, it is great. It is better suited for lighter use, so it is not for tech experts.

It makes it to our list because it is a very economical and practical option for drill bits. There is an extensive range of sizes that make the 21-piece set a success. Its 30-day money-back guarantee also distinguishes it as the customers find it very helpful. If you do not like anything in it, you can get your money back within 30 days.

People who bought these lately gave good reviews mostly. They liked how these are better than other drill bits due to their length. This made them replace their old drill bits as they would not drill such deep holes. They also approve of its high-speed steel construction, which does not undergo much damage. 

Why it Stands Out to Us

It stands out to us because of its length and high durability. The 5 drill bits have sizes of 1/8 inch, 3/16 inch, 1/4 inch, 5/16 inch, and 3/8 inch. This size range helps users in multiple tasks where different metals are involved. We find the laser-engraved sizes on the drill bits impressive, too, as they make working with them easier.

Who Would Use This Most

This drill bits set is more suitable for homeowners than professionals. They are not heavy-duty, so they will not be able to deal with excessive usage. As you need them less frequently at home, it is better for home-usage. 

Bottom Line

These drill bits are very useful on the whole as they have multiple sizes which fit in all situations. The spiral flutes in them help to avoid walking and slipping, but still, you should be careful. This is a good choice for you, especially if you are on a budget.

Why it Stands Out to Us

It makes it to our list because of the cobalt coating on high-speed steel drill bits. It makes them so strong that you can enjoy using them for years if you know the right techniques. We also like its case, which has an interlocking hinge and sliding in it.

Who Would Use This Most

This is more useful for professional workers than users at home. The drill bits are heavy-duty, and they can be tricky to use as their speed is hard to handle. The cobalt coating makes them more prone to heating up as well, so these are for expert use only.
