Best Drill Bits for Metal

1. DEWALT Titanium 21-Piece Drill Bit Set

The DEWALT Titanium 21-Piece Drill Bit Set is a great mid-range set of drill bits that is appropriate for metalworks.

Does that make them the right set for your needs?


The DEWALT Titanium 21-Piece Drill Bit Set is a reliable product from a well-known brand.

People often turn to DEWALT for buying not only drill bits but also for investing in drills themselves.

The drill bits in this set are of metal, wood, and plastics materials. Today’s review focuses on why they are a great option for metal-related projects.

  • Speed Tip

The speed tip on these makes it so that you can very easily drill through soft materials.

It has the right cut and sharp tip necessary for cutting quickly.

That being said, your can cut into very hard metals with these drill tips if you cut at a low speed rather than trying to race through it.

The tips can get through softer and thin sheets of metal easily without going too slowly. However, you have to drill harder metals slower to prevent excess heat build-up.

  • Shank Prevents Spin

The shanks on these drill bits are three flat shanks that prevent spin while you are drilling. This is important for drilling accurate and straight holes.

What’s more, no need for special chuck adapter to fit these into most standard drills.

  • Durable Organizer

Many found that the case included with these bits is one of the best around. It is durable and easy to use and keeps everything organized.

The case is a good size, too. It can fit into a large pocket or into a tool bag without the bits coming loose.

Even then, it remains hassle-free to take the bits out when you need to use them.

  • Titanium-Coated HSS

The drill bits are titanium-coated HSS, which gives them a longer life than standard HSS drill bits.

The titanium-coating improves the drilling ability when working with non-ferrous metals.

  • Various Sizes

This 21-piece set includes sizes that range from 1/16 up to ½ of an inch, so you will be able to handle most of your drilling needs with this single set.


  • Titanium-coated HSS
  • Great for many metals and soft materials
  • Easy to fit into drills
  • High-quality case included
  • Great for home use


  • Not professional-grade
  • Very small sizes are less durable

2. CO-Z 5-Piece Step Drill Bit Set

Next up is the CO-Z 5-Piece Step Drill Bit Set.

This affordable set of step drill bits is a great option to use for boat enthusiasts who like working on their own boats.


This five-piece set of step drill bits from CO-Z boasts cobalt HSS tips that are of titanium coating for a great balance of price and durability.

The bits have five sizes, and each one can cut up to 10 different steps depending on how you use them.

  • 50 Sizes in Total

In total, these step drill bits can create 50 different sizes; each drill bit has 10 steps.

The drill bit will hop smoothly between each step, depending on what size hole you need to make.

While some drill bits “hop” too much between steps, this one does so smoothly so that you can continue working without interruption.

You also get the step rings with labels, so you always know what steps you are working with.

  • Non-Walking Design

When using a step bit, it is especially important that the bit doesn’t lead to the drill rocking back and forth, or the hole will not be even.

The non-walking drill tip on these bits helps to ensure that they can drill smoothly into sheet metal without sliding to the sides and causing unwanted openings.

Smooth hole drilling is possible with these step bits.

  • Organized Case

The bits in this set are in a well-organized case.

This case keeps the bits in place with their size labels so that you will be able to quickly recall what sizes you have available.

  • Smooth Cutting

In addition to cutting without moving from side to side, these step bits have two flutes to ensure smoother cutting.

The two-flute design ensures any metal shavings from the drilling process are far from where the cutting is happening.

This lets the bit continue to work without the metal flakes getting in the way.


  • Different sized bits for different metal thicknesses
  • Up to 50 different sizes possible
  • Smart design for better cutting
  • Cobalt with titanium-coating
  • Well-labeled bits and case

However, the tri-flat shanks have universal sizing to work with most drills.

  • Easily Identifiable

Each of these step bits has the sizes clearly engraved into the inside of the flute on the step bit.

This makes it so that you can clearly see which size you are on even when you have already started drilling.

  • Better Cutting Angle

The split point on these step bits is a 135-degree tip. This angle helps to ensure that you can cut into the metals more effectively and speedily.

Additionally, this angle does not wear out as quickly as others, so you can expect the tip to have a good amount of durability.

  • Good Construction

These step bits are from HSS and with titanium coating for better durability.

They will be able to cut through plastic, copper, stainless steel, copper, and more for multiple drillings without wearing out.

5. COMOWARE 10-Step Drill Bit

Finally, let’s take a closer look at the COMOWARE 10-Step Drill Bit. Will the 10 sizes that can be cut by this drill bit be enough?


This step drill bit from COMOWARE can cut these sizes with just a single bit: 1/4, 3/8, 1/2, 5/8, 3/4, 7/8, one, one and ⅛, one and ¼, and one and ⅜ inches.

Though this is just a single bit, it can do the work for many different boat projects.

  • HSS with Titanium-Coating

This drill bit is made from high-speed steel, and it has a titanium coating on it.

The titanium coating ensures that the durability and sharpness of the bit will last longer. This is because it lowers the amount of friction that causes the bit to degrade over time.

Additionally, titanium runs cooler while drilling than the HSS, so this helps to ensure the longevity of this bit, as well.

  • Various Materials

This drill bit can be used on a variety of sheet metals as well as copper, plastic, wood, boards, and more.

Because of its small size, it’s not an ideal choice to cut through materials that are thicker than ⅜ inches.

Still, it might be used with the addition of cooling oil and slow, consistent pressure.

  • 118-Degree Split Point

This particular design from COMOWARE has a split point tip set at 118 degrees.

This particular angle should help to improve the wear resistance of the bit so that it can last through even more uses.

  • Three-Flat Shank

In addition to the overall good design, the actual shank on this drill bit is a three-flat shank.

These types of shanks are known to grip more successfully in most drill types, which means that the chances of slipping or shedding will be significantly reduced.

Slipping can be a bit problem when you are using step bits because of the way they hop between sizes, so this shank design is ingenious.


  • Can be used with cutting oil
  • Titanium coating prevents immediate friction problems
  • Does the work without added force
  • Great for at-home use


  • Not strong enough for some commercial applications
  • Long-term durability issues

For those working on boats, in particular, the Neiko 3-Piece Titanium Step Drill Bit Set is going to be a great option.
