What Do You Need to Know When Selecting the Best Drill Bits for Metal?

Drill bits come in all shapes and sizes, but they can be broken down into four basic categories. Standard drill bits are made for standard corded drills and work best on materials like wood or plastic.

The Cordless category covers bits that both use a battery-powered drill to create holes as well as any bit that is compatible with the aforementioned type of drilling device (i.e., it will fit).

Bits designed specifically for metal drilling have been further classified by ferrous metals such as cast iron or nonferrous metals including copper, tin.

Drill Bit Material

Drill bits are made from three main materials: high-speed steel, cobalt, and carbide.

High-speed steel (HHS): is an all-purpose drill bit that can be used to drill through ferrous metals like iron or stainless but also nonferrous ones such as aluminum or brass.

Carbide: metal drilling bits work well for drilling nonferrous metals like copper but aren’t so great at boring through ferrous material types such as cast iron.

The Cobalt: drill bit is designed for use with ferrous metals but does not work as well on nonferrous. Cobalt has the ability to drill through tough materials like steel with ease because it doesn’t rust or corrode easily.


Titanium and black oxide coatings on drill bits are designed to reduce friction, which in turn helps the bit from heating up too quickly.

This reduces wear-and-tear of the metal during drilling operations so that it can endure longer without breaking down or wearing out prematurely.

These coating also allow a drill’s rotational speed to increase by as much as 20%.

Shank Design

The shank is the non-drilling end of a bit that fits into your drill’s mandrel or chuck. It’s typically ¼-, ⅜-, or ½-inch and should match the size of the drill you are using.

Some designs for this type of bit work better with metal than others, so be sure to take note of what works best for you before buying more expensive bits without knowing if they will help at all!

No-spin shanks are designed to keep you from slipping when drilling into hard metals. A hex shake has six sides that help it stay steady while in use, and is a great choice for long jobs like metalworking or construction.

Tips for Buying and Using Drill Bits for Metal

Great for DIY projects, drill bits are the go-to tool when it comes to making holes in wood or metal. But before you start your next project, be sure that you’re using a high-quality bit with sharp edges and tough materials like steel or titanium.

Not only will these drills make an easier hole but they also won’t break as easily!

If you want smoother holes without any hassle then don’t forget to invest in some of those handy dandy tools known as drill bits!

Be sure not just buy any old thing; look at the type of material used (steel? Titanium?) and what size hole is best suited for your needs—a mistake can lead to ruined furniture pieces or worse have hazardous consequences if

To make drilling easier on your hands and drill bits, use a center punch to create a depression in the metal before you start. This will reduce the likelihood of slipping off or breaking because it creates more surface area for contact with each other.

To lubricate while drilling through materials such as steel, add three-in-one oil or cutting fluid; this reduces wear and tear on your bit by increasing its longevity during long jobs like putting together an engine block from scratch!

The friction caused when using drills can also cause overheating which is why if you are tackling larger tasks that take longer than 15 minutes per one-inch-thick material drilled, then break every five minutes to let your bit cool down sufficiently.

Frequently Asked Questions (FAQ)

Metal-drilling bits are a must-have for any metalworker. Knowing which drill bit is the perfect fit can be confusing, but this article will make it easier to choose just what you need!

Help me pick a Drill Bit Between Cobalt or Titanium

Choosing the right type of Drill Bit depends on what material you’re planning to drill. If you’re planning to drill through a softer metal like aluminum, then Titanium bits work best. On the other hand, Cobalt drill bits are perfect for drilling through hardened metal like cast iron.

Who makes the best drill bits?

Some manufacturers of drill bits think they are worth more than others because of how specialized they are. This article is going to cover the top ten drill bits that are the most popular, but keep in mind, every company thinks their drill bits are the best.

How to Sharpen Drill Bits For Metal?

Drilling is a difficult task, even for experienced DIYers. But if you don’t sharpen your drill bits when the cutting edges become dull and they have trouble drilling holes then it’ll be more challenging than ever before! If this sounds like something that would happen to you, I recommend taking 10 minutes out of your day to do some careful sharpening on all those old drills in the garage – or at least keep them handy so next time an important hole needs drilling (underneath my kitchen sink) there’s no excuse not to get down-nitty gritty with a bench grinder.

How To Remove a Broken Drill Bit From Metal?

It is easy to remove a broken drill bit by adding some lubricating oil and then gripping it with pliers. First, pour on the grease or add in an extra drop of cooking spray before you grip the shank securely with your tool. Then twist counterclockwise until all that remains are scraps poking out from a hole where there used to be something sharp!


If you need to drill through tough metals like steel or titanium, we’ve got the best drill bits for hard metal for your job.

Whether you’re a professional contractor who needs to work quickly or an amateur tinkerer that just wants to get it done right, we have what you need!
