Drill bits are available in many shapes, sizes, and sorts and may be used to bore holes in various materials. As a result, many home improvement shops devote an entire lane to drill bits. 

There are a variety of drill bits available, and most of them can drill through more than one material; however, not all drill bits can drill into metal without overheating and breaking. 

There are labels on drill bits that show the kind of material they are suitable for—because of this, locating drill bits made to drill metal is not challenging. Some drill bits are more suited to the job than others, and this is mainly determined by the type of metal you are drilling.

If you are working on a project that needs you to drill into metal, read about the aspects you should consider before hopping for the best drill bits for metal. This information is helpful if you are working on a project that requires you to drill through metal. The following sets of drill bits are superior to their competitors and will assist you in making holes in various metals.

How Drill Bits for Metal Different From Other Drill Bits?

Most metal-boring drill bits are constructed of high-speed steel (HSS). HSS is a robust alloy that can survive the heat and wear created by drilling metal. This is because HSS is a nickel-based material. Other types of drill bits, such as those composed of carbide or cobalt, are also capable of drilling metal; however, they are not as durable as HSS drill bits and are more likely to shatter.



1. Chicago Latrobe 57714 150 Series High-Speed

Do you have considerably larger money to deal with than what we’ve spoken about so far, and do you want to invest in something quite powerful, right down to the casing itself? If this is the case, we have a sneaky notion that you could get along a little better with something similar to this tiered pack drill bit set from Chicago Latrobe.

These components come from a metal box outfitted with racks arranged by size. These racks fold forward and are engraved with the bits’ dimensions, making it exceedingly simple to locate the particular size you are searching for. 

When used for drilling, the 29 bits are constructed of steel and coated with a long-lasting black oxide finish. This helps protect them from being cut by sharp metal edges. Each one has a standard point, and their lengths span from 1/16 inch to 1/2 inch, much like the previously described kit.

Product Features:

  • This set of 29 jobber-length drill bits contains diameters ranging from 1/16 inch to 1/2 inch, with increments of 1/64 inch.
  • High-speed steel, sometimes known as HSS, is known for its extreme hardness and wear resistance.
  • On ferrous material, a black oxide finish will promote chip and coolant flow while reducing the amount of wear on the bit.
  • typical point with an angle of 118 degrees for use in a variety of drilling applications
  • A jobber-length drill bit has a drilling depth that falls in the middle of the range, making it ideal for general-purpose drilling tasks.

2. DEWALT Cobalt Drill Bit Set

We believe you will likely like the price point and the quality combo of this drill bit set made available by DEWALT.

The fact that this particular kit only contains 14 pieces instead of over 20 makes us feel comfortable obtaining fewer sizes, particularly given that they are still within a good basic range. 

The affordable price that comes with it also makes us feel okay obtaining fewer pieces. The structure of these bits, which is made of robust steel, as well as the strength and efficiency of the pilot point tips, are both deliberate design choices made to make them suitable for usage on hard metals

Even when operating at the highest possible speed settings, the producers purposefully constructed the bases to ensure that they remained firmly grounded even under the most demanding conditions.

Product Features:

  • The design of the patented bit-bar enables the simple removal of drill bits and their customizable positioning.
  • The clear cover that comes with the DEWALT drill bit set enables you to assess the contents of the container quickly.
  • The closure is made more secure by the clip latch.

3. Craftsman 9-64085 Professional Cobalt Drill Bit Set

Have you already looked at quite a few different drill bit sets that have details that you’d find helpful, but you haven’t been able to commit to buying any of the sizes ranges that you’ve seen, so you’d want to do a little more browsing before making a purchase? Then in addition to that, we would also recommend giving this metal-friendly drill bit kit from Craftsman a thorough inspection.

There are 21 drill bits included in this kit, which is housed in a robust and lockable flat plastic box. As opposed to being manufactured from titanium or coated steel, these bits are made from cobalt, another hard metal capable of resisting drilling via other metals, even at the fastest speeds. 

The sizes vary from 1/16 inch to 3/8 inch, and the points on each are meant to decrease “walking,” which is when the drill bit hops over the surface of the metal a little before cutting into it. Because of this, you will achieve higher precision and more steady experience.

Product Features:

  • Drill bit sizes ranging from 1/16 to 3/8 inches.
  • Includes a carrying case made of polypropylene.
  • Developed for use in heavy-duty applications across all types of metals, including hard metals.
  • A split point that drills on impact, doing away with the need for “walking.”
  • Excellent for use in stationary devices such as drill presses.

4. Drill America – KFD29J-PC 29 Piece Heavy Duty

Are you still interested in long-lasting metal parts containing at least 20 individual pieces, but you’re unsure whether or not a large, flat box similar to the one you saw earlier is actually what you require? 

It’s possible that what you’re searching for is an alternative equivalent to what you saw earlier, but since you have a larger budget, you aren’t feeling quite as firmly bound to the requirement for a discount. In either case, we strongly recommend that you look into the kits that Drill America offers.

This space-saving cylindrical casing accommodates even more parts than the flat one you saw earlier, which is remarkable considering that this kit has 29 individual components. The bits themselves are jobber length and come in sizes ranging from 1/16 inch to 1/2 inch, with 1/64 inch increases between each size category. 

They are constructed out of high-speed steel that has been purposefully intended to withstand wear and tear even when used on the highest power settings available on your drill. In addition to helping to prevent corrosion over time, its black and gold oxide finish looks excellent.

Product Features:

  • High-speed steel, sometimes known as HSS, is known for its extreme hardness and wear resistance.
  • The drill bit’s corrosion resistance is increased along with its hardness thanks to the black and gold oxide treatment.
