I am done with the reviews of best metal drill bits surfaces. You have already seen the choices above and their specs. I am sure you have adopted one already from the above list.

Before you hit the link and ensure your product, let us go through the following section. There I will discuss some useful buying tips. After that, you will understand which product is useful for your task and which one demands to ignore.

Things To Consider Before Buying Drill Bits

Though I have reviewed some of the best drill bit for metal, yet you should not make any deal. Are you wondering why? It is because the best depends on your requirements.

If you need something and your drill bit provides something, no matter how good it is, the product is of no use to you. This is the reason you should carefully read this section to know all the subtle details of drill bits. Let’s get started without wasting any more of your time.


The first thing to consider is the material. If you need to drill some holes on the metal surface, material plays the most significant role. Not all the materials can deal with the hardness of the metal, right?

You need to have the bit that is even harder than the surface you wish to work on. There are certain options for you in terms of materials. Let’s see and consider which material type is required for metal.

Soft-Low Carbon Steel Material:

  • Cheapest materials
  • Low carbon percentage
  • Don’t hold the edge correctly on metal
  • Needs recurrent sharpening

High-Carbon Steel Material: 

  • Known as Carbide
  • Work well on metal
  • Lose sharpness on the edge if exposed to high temperature for an extended period
  • Useful on Wood as well

High-Speed Steel Material:

  • Heat resistant and harder compared to High-Carbon Steel
  • Ideal for extended projects
  • Offers quicker cutting speed
  • Good for metal surface

Cobalt Steel Alloys Material:

  • Best for hardened drill bits
  • Contains a higher percentage of cobalt
  • The higher temperature is not a problem
  • A bit more bitter compared to other materials

Tungsten Carbide Materials:

  • Hardest among all the materials
  • Ideal for an extended period
  • For metal, they are the most effective material

I have included all the materials and their features above. I will not tell you to pick this or pick that. It is up to you now.


Coating is another most essential factor to consider while buying drill bits for metal materials. The coating is necessary for the durability of drill bits. Let’s see different types of coatings and their features. In the end, you will be able to determine which coating is suitable and which coating is not.

Black Oxide:

  • Comparatively cheaper
  • Excellent heat resistant
  • Low Friction
  • Boost durability
  • Good corrosion resistance

Titanium Nitride:

  • Comparatively hard
  • Works well against a wear-resistant surface
  • Increase durability
  • Made of ceramic

Bronze Oxide:

  • Auxiliary coating
  • Commonly used with cobalt steel or Black Oxide coated drill bits
  • Help with stress relieving

Now you know the benefits of the top three types of coating. It is your turn to decide. I am not suggesting anything as I have already told you the benefits of each coating method. Decide wisely according to your needs.


Now you know about drill bit materials and coating, it is your time to know about the types. You will notice several drill bit types on the market. Let’s see each of them briefly:

  • Twist: Most common, can be used with manual and electric drills both.
  • Screwdriver: Comes with a hexagonal shank, limited power, ideal for pilot holes.
  • Masonry: Used for brick, concrete and tiles, cutting edge is made of tungsten carbide and spiraled steel shaft.
  • Spur Bits: Comes at size ranges from 3mm to 10mm, ideal for Wood, Plastic, and metal surfaces.
  • Tile Bit: Ideal for glass and tiles, made of the tungsten carbide tip, looking simple and easy to use.
  • Flat Wood: Used commonly with a power drill, ideal for Wood.
  • Hole Saw: Used to fix large holes, able to dig into 18mm deep.

All the types mentioned above are ideal for various tasks. You can pick one or multiple tips. On our best metal drill bits articles, you will find several options that have every type of bit included. You can select any of them if you need all kinds of drill bits.

Shank Design: Shank is the part of the bit that attaches to the machine. Considering the shake design is another essential factor to consider. If the design of the shank does not match with your chuck of the power tool, firm attachment is impossible.

You should check the chuck of your machine and go for a bit that has a round shank or hexagonal shank. Hexagonal Shank is better as they provide a better attachment with the chuck.

Number of Pieces:

It depends on you actually and on your requirements. If you have a workshop, a set of 230 to 250 pieces will be an ideal choice. For home use, you can pick a set that contains less than 50 pieces.

Important FAQ of Metal Drill Bits

Q) Will a metal drill bit work on tile?

A) Some may work, but that requires a hell lot of skill; otherwise, you may ruin the tile. We do not recommend picking metal drill bit for tile. You will find specially designed drill bit for tiles in the market. Go for one of them.

Final Words

I am not gonna declare any best pick from the above options. In my eyes, all those eight products are best in every possible way. They just differ in number and cost. All of them can provide high versatility and incredible features. Pick any of the above that suits your requirements. You will be amazed, I guaranteed.

Remember having the best metal drill bits will make your job more comfortable as well as safer. Moreover, wrong product choice can lead you to a horrible experience. In the end, your safety is what matters the most.
