What Can Drill Bits Do?
Drill bits are basic cutting tools that come in handy when you need to remove material to create holes, usually rotational holes. The stronger your drill bit is, the more penetrative its power. Some bits can drill holes into softer materials, while some are designed for harder materials. Also, some are meant to drill smaller holes, while others drill larger holes. Your focus should, therefore, be on getting the bits that are most suitable for your work.
It can be quite frustrating to drill a hole through metal with a drill bit that just isn’t working right. You should not have to apply too much pressure to the bits to get the job done. If you have to apply more and more pressure just to make a hole, your drill bit is not sharp enough and needs to be changed. A dull drill bit does not only render your work pointless, but it also damages your drill.

To avoid the element of surprise when you go shopping, we have summarized the best types of drill bits for metal for you.
Center and spotting drill bit
Also called Slocombe drill bits, center drill bits are used in making a conical indentation for mounting a lathe center at the end of the workpiece. Spotting drill bits, on the other hand, are meant for drilling a starting hole for a larger drill bit. Both tools are numbered from the smallest to the largest as 00 to 10.
Core drill bit
One form of core drill bits is the one that is used for enlarging an already existing hole. This bit is solid and can double the size of a hole. It looks like a reamer because it does not have a cutting point for starting a hole.
Another form is a hollow bit with a cylindrical shape that can cut holes with an annular cross-section while leaving the core of the material intact, usually removing it. Its main function is to get the core and not just make a hole.
Hole saw bit
This type of metal drill bit is well-known for its ability to cut the smoothest holes. It can achieve this by its design. Hole saw bits have a circular saw which cuts through while the drill feature firmly holds the teeth of the saw so that it does not move unnecessarily. Depending on the way they are made, this type of bit can cut through all manner of materials.
Split point bit
This is the best choice of the drill bit when you want to work with metals. It is beautifully crafted to help ensure that the drill is well balanced when working on hard materials. All the drilling points of this tool are very sharp to ensure you have a smoother cut.
Twist bit, also called the Morse bit, is a versatile work tool that can be used on almost all materials but adapts better to metals. The downside of this bit is that using it can be a bit of a challenge because of its high speed, especially if you need precise drilling acts.
Generally, bits can be made from different materials. Some are made from inexpensive, low carbon steel, while others are made from high-speed steel (HSS), titanium, or carbide.
Bits made from steel are budget-friendly and will have to be sharpened from time to time. They are great for softwood and are likely to quickly become dull or break if used on hardwood.
High-speed steel bits
The bits made from high-speed steel work best with metal, wood, and ceramic. HSS bits are very popular and reasonably priced. They are harder than steel bits and stay sharper for a longer time. Additionally, they are highly resistant to both heat and torsion.
Titanium coated bits
Titanium is a very durable material and will ensure your bits stay sharp for an extended period. They are pricier than HSS bits and can drill through thick metal.
Carbide tipped bits
One of the most robust bits is the carbide-tipped bit, which can easily go through any material, including stone. They are the highest quality of bits and are costlier than titanium coated bits. These bits are the most durable of all the bits and stay sharp the longest.
These special bits are made for drilling through stainless steel and any other metal. Cobalt bits can be used to dissipate the heat from any material that causes a heated build-up as a result of friction. Made with both HSS and cobalt, these bits feature a very flat, blunt tip. They remain sharp for a more extended period.
What is your budget for the best drill bit? The amount of money you are willing to part with depends on the task you are buying the drill bit for. Some bits are made for specific functions hence, they are sold separately and can be pricy when bought as a set. There are also drill bits that come as a basic package with a few bits for regular drilling tasks. Professionals, however, prefer to go for the entire drill bit set. What you are willing to pay for depends on the quality of the bit and your budget.
So, if what you need is just a few sizes for your work, you may want to get just those sizes instead of spending on a set that has sizes you may never use.
When using your drills, wear working gloves, a dust mask, safety eyewear, hearing protection, and other safety gadgets recommended when utilizing power tools.
