Don’t get me wrong here, drilling through metal – as annoying as it can be at times – is actually a fairly simple process to do if you have the correct set of tools like the best steel cutting drill bits or diamond heads. In fact, it is more or less like cutting through wood or stone – It is just that easy. Having the best metal drill bits is the key to making a perfect cut, and that is exactly where things get a bit more complicated.
Mind you – Pretty much any best bits for drilling steel can somewhat get the job done well; however, having the “perfect” best metal drill bits at your disposal can literally make all the difference in the world. Aside from just making your projects turn out awesome, having the best metal drill bits would also mean that the efforts you put into them would also be minimized to the degree that’s not excessive or overt.
The fact of the matter is, if you want to drill into metal, there is no real getting around the fact that you are going to have to invest in a few good metal drill bits that are better apt for the job. In this review, I am going to point out a few of my favorite best metal drill bits for the year 2021 that I think is the best of what the industry has now in its offing.
Best Metal Drill Bits: The War between HSS, Carbide, and Cobalt
Best metal drill bits are known to come in a lot of shapes and sizes, and they are available in a slightly wide variety of base materials and coatings. From standard to unique, most tooling and machining operations out there would have a best metal drill bit set that’s been specifically made for it, and that is pretty much the case with any other. Here is an instant overview of the three different types of best metal drill bits models that are now available on the market.
Best Drill Bits for Wood and Metal
Here are my top picks for the year 2021
#High-speed steel (HSS)
A rather stock option when it comes to best metal bits, the HSS or High-speed steel is perfect for drilling through soft materials such as generic steel, plastic, and wood. An affordable option well-liked by many, this particular set of drill bits is perfect for household chores and minimal work options.
#Cobalt (HSCO)
An improvement over the normal run-of-the-mill HSS drill bits, these rather tough and durable best drill bits for steel plate comes with a certain make that is blended with at least 5-8% of Cobalt mixed into them. Extra resistant to heat and abrasion, these durable drill bits are perfect for tackling tougher materials such as iron, stainless steel, and hardened alloys.
#Carbide (Carb)
Perhaps the strongest of the bunch, the Carbide infused best metal drill bit set are perfect for use in high-end stationary drilling modules where powering through the material is the general norm of the hour. Not to be used with hand drills and even drill presses, these particularly strong best metal drill bits are custom designed to tackle the hardest and demanding materials you can think of.
Almost all the general purpose drill bits are great to deal with metals. At the same, the drill bits manufactured for metals are multi-purpose to drill wood, plastic, etc. Still, if you are more specific, the twist bits made of high-speed steel are less expensive and fine for drilling any metals.
If you want to drill a lot of holes or drill through hard metals like stainless steel, then you have to invest a little in some specific tools. Like the drill bits that are made of black oxide or cobalt steel, exclusively for metals.

Offering a cheaper way to cut & drill through your life, the metallic drill bits are amazing in the sense that they bring a lot of versatility for too little cost. But hey, with anything cheap, questions also come just behind.
To help you, the customer make an informed choice, here are a quick FAQ to help you break down these awesome drill bits
Read on;
1) Is titanium coated bits better than regular ones?
Yes, of course, they are. With a titanium-coated metal bit, you can enjoy fast performance, heat reduction, and yes, cleaner cuts. Besides, they can also help enhance the longevity of the bits as well – doubling, even tripling their lifespan.
2) Can they handle hammer action?
Of course, they can – at least the costlier ones, that is. For a bit to be hammer supported, it needs to have extra edge reinforcement, which thankfully is the case with almost all the bits we have featured above.
3) Can they be used on rocks too?
Yes. But your mileage may vary depending on the quality of the drill bits. That said, you won’t have any trouble with most materials like Granite, marble, tiles, etc… In fact, some metal drill bits are even ready to chew through ceramic!
Again, it all depends on the drill bit. Therefore, always refer to the manual first before putting the metal to the ground.
4) What lubricant is best for them?
MQL or Caster oils are best if you are cutting through metal. For other materials, especially geological, you can find custom cutting fluids that are best for them. In any case, lubricants are a must for metal bits.
5) Are the best metal drill bits in 2021 review models cheap?
Considering other options like a diamond, carbide drill bits, etc… metallic drill bits are fairly affordable. Heck, even the T-coated ones too are super cheap.
Conclusion
As brief as it was, I hope that this review has given you a better sense of what best metal drill bits are all about and which are the various models you can buy right now.
Designed to drill through anything, these high-end best steel drill bits are perfect for both personal and professional uses. Most of these are universally adaptable and therefore, not getting a perfect fit is a never a problem you need to worry about.
