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.

Review of the Best Drill Bits For Metal

In order to make the most out of a drill bit, you have to check its compatibility with your needs. Keeping this in view, we have brought you a complete review of the best ones you can opt for to cut through metals.

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.

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.
