What type of Drill Bits to use for metal?

Not all drill bits can be used on metal without heating up and snapping in half.

Regarding metal, there are two types of drill bits that you can count on for metalworking projects: titanium and cobalt.

Titanium (Finish):

Drill bits made with a Titanium nitride coating resists abrasion and friction. It also increases surface hardness and does a good job of reducing heat while drilling through metal. These are the bare minimum for metal drilling.

With titanium nitride, you have to remember it only coats the bit. You will have to replace them as soon as the coating wears off the cutting edges. It’s also better not to use these bits for drilling hardened steel or stainless.

Cobalt (Steel Blend):

Cobalt drill bits are made to last. They’re constructed with a rigid mixture of steel and cobalt.

You can buy drill bits with different cobalt concentrations: The M35-grade cobalt drill bit set contains 5 percent cobalt (like the previous COMOWARE Colbat Set), whereas M42 grade cobalt drill bits contain 8 percent cobalt (such as Bosch CO14B).

Even if cobalt drill bits are more expensive than the rest, the durability they provide is worth the money. They’re also well-made and tough, which means they will not dull quickly. Cobalt drill comes in a goldish color, making them easy to spot amongst your tools.

Now that you read all the recommendations plus the tips we gave you about The Drill Bits for Metal. Remember that our list covered models for both occasional and professional daily use. Therefore, before making your purchase, you need to consider:

How much work you need to do with these bits, along with your budget for it.

On top of that, the most important aspect you need to remember while buying a drill bit set is your drilling material. If you’re going to drill any thin metal sheets, a thin bit can do this very well. But drilling thick steel workpieces need stronger types of bits like those we mentioned at the bottom of the list.
