A drill bit is a power cutting tool that is used to make holes in different materials. Typically, the holes are made with a circular cross-section.
Drill bit sets are available in all sorts ofshapes and sizes and are used to create various types of holes in all sorts of materials.
Drill bits create holes by being attached to a drill. The drill, in turn, gives them the power to cut through the material, usually with the help of rotation. The drill then grasps the upper part of the drill bit which is called the ‘shank’ in the chuck.
Drill bits are generally pretty simple products. They are designed keeping in mind only a single purpose – to effectively and quickly drill a hole into a particular material.
A drill bit set can be useful whether you are working on a certain DIY project such as a repair within your home, or a more large-scale project such as building a house.
When choosing the best drill bit set to purchase, you must think about certain factors such as what sort of a hole you want to drill.
Your main considerations should be that your hole is geometrically accurate and that it looks smooth. It’s always a plus point if you can drill the hole efficiently and quickly without wasting any time.
In most cases, a single drill bit isn’t enough to do a great job, and you will require a drill bit set. You must select your drill bit based on which material you want to drill.
Drill bit sets are easily available at any home improvement store. There are different types of drill bit sets available for varying materials.
For example, a high-speed steel (HSS) drill bit set is an economical choice for materials such as wood, plastic, and soft steels. Cobalt (HsCO) on the other hand, is recommended for drilling into tougher materials such as harder steel and stainless steel.
Meanwhile, Carbide (Carb) is perhaps the hardest of all drill bits available, and is mainly for production purposes. This sort of a drill bit should never be used at home in DIY projects.
Make sure that you purchase a drill bit set based on its performance and not the way that it looks. Sometimes a beautiful-looking drill bit set performs poorly and is, therefore, useless.
The three things that you absolutely must think about when choosing the right drill bit set are the material you want to drill into, the sort of hole you want to make, and the way in which you want to make it.

Cordless Drill Bits for Metal FAQ
What drill bit is best for metal?
Generally speaking, jut any drill bit isn’t capable of drilling through a hard metal. You will require a heavy-duty drill bit that works best with tough materials.
Titanium drill bits are high-speed steel drill bits (HSS) that have a titanium oxide coating. These are usually very hard, and are also corrosion-resistant. They tend to last significantly longer than regular HSS drill bits. These tend to be really effective for cutting through any metal, even metal sheeting.
Furthermore, Cobalt drill bits that are made up of cobalt steel are also good for drilling tough amterials such as metals. Cobalt steel is hard and heat resistant and so cobalt drill bits also work well with metals such as stainless steel, cast iron and titanium.
How to use a drill bit for metal?
The first step is to correctly mark the spot you will be drilling. You can use a tape measure and a pencil to mar this spot.
Next, you need to use a small center punch, of about two millimeters to put the point of the punch on the mark you had initially made. Tap this with a hammer to create an indentation in the material.
This hole will allow the point side of the drill bit to settle within it and prevent the drill bit from skidding.
After marking everything, you will need to place your item flaton the surface and use clamps to clamp it up nice and tight. Allow enough space between your clamps and the drilling point to make sure that your drill gets in comfortably.
You don’t want to be stuck in too much of a confined area as this can easily lead to mistakes and potentially injuries.
Before drilling, make sure to use some lubrication. This ensures that the heat build-up is massively reduced and that any chance of drill bit damage is reduced as well.
With everything ready, you must drill out a small hole first, about four millimeters in diameter. Move up the hole to six millimeters.
Ensure that the chuck is tightened properly and place the tip of the bit directly over your punch point. Once you have made it all the way through, pull the drill bit back and place the drill to one side.
Wipe everything down and remove any excess lubrication.
What is the best drill bit for hardened steel?
If you are in search of a drill bit that works best with hardened steel, you must go to a home improvement store that specializes in drill bits for steel.
Usually though, cobalt drill bits tend to work best with hardened steel. This is because cobalt is very hard, abrasive, and heat resistant.
Is cobalt or titanium drill bits better?
Both cobalt and titanium drill bits are effective in their own way, especially when it comes to drilling hard metals. Titanium coated drill bits generally tend to last up to six times longer than any standard High Speed Steel drill bits.
Cobalt bits on the other hand are designed particularly to be used with hard, abrasive materials. These include stainless steel, titanium and cast iron. Cobalt bits are never designed to be used generally.
As such, cobalt drill bits may be a better option when it comes to drilling hard metals, although both can do a decent job.
These are some of the best drill bit sets for metal out there today. Get your hands on some of these if you planning on drilling metals any time soon.
