Your conventional or wireless power drill provides the energy, but it’s the drill bit that truly gets the job done, whether it’s screwing drywall, drilling a hole in metal, putting together furniture, or punching a small hole in the glass. Since certain particular drill bits are offered separately, you’re more likely to buy a set that contains a variety of sizes and uses, allowing you to work on a number of projects around the house. You’ll have to know the size of your drill’s shank clamp on the front of the drill that holds the bit–when picking the best drill bits in 2021 and beyond. The shank of your drill bit (the bit’s base) cannot be bigger than the head of your drill.
As there are a lot of brands and types of drill bits available in the market, picking out the top product can be challenging. To help you make the best choice, we have curated this detailed buyer’s guide.
What are the different kinds of drill bits available?
Auger drill bits
Auger drill bits have a unique appearance, with sharp helical spirals called “flightlings” along their shaft length. They’re made to make smooth, consistent holes in wood while also getting rid of the shavings. Auger drill bits may be used to cut through the ice as well.
Cobalt drill bits
Cobalt drill bits sets are high-capacity tools. Especially though the pieces are largely constructed of steel, a 5% cobalt admixture adds strength and heat resistance, even when cooling is restricted. Cobalt drill bits may be used with high tensile metals or metals that keep their strength under stress.
Hex drill Bits
Hex bits have hexagonal shanks that are either machined onto a round shaft or derived from a hexagonal bar in the first place. Professionals and DIY enthusiasts alike will benefit from hex drill bit sets, which include a variety of the most useful bits.
Micro drill bits
These are tiny pieces that are suited for close-up work. Steel, aluminum, brass, polycarbonate, and glass fiber are among the materials that they may be utilized with. Micro drill bit sets are generally available in sizes ranging from 0.5mm to 2mm.
Jobber drill bits
Jobber drill bits are long and thin, with a length of 9-14 times the diameter. They’re one of the most common drills bit kinds, and they’re good for a variety of less difficult applications. Some jobber drill bit sets are rather large, with a wide range of lengths and diameters to choose from.
What to look for when purchasing a drill bit?
The materials used to make bits, as well as the finishes applied to them, have a major impact on the bit’s life and performance. Materials that are commonly used include Drill bits made of high-speed steel (HSS) may be used to drill wood, fiberglass, PVC, and soft metals like aluminum. Drill bits made of cobalt are exceptionally robust and swiftly disperse heat. They’re mostly used in aluminum and strong metals like stainless steel for boring. HSS drill bits with a black oxide coating are designed to prevent corrosion and enhance endurance. They last longer than standard HSS bits and may be used on metal, hardwood, softwood, PVC, and fiberglass, among other materials. HSS drill bits with a titanium coating have reduced friction.
When it comes to drill bits, there are two sizes to consider: the shank and the tip. The shank is the portion of the bit that goes into the chuck of your drill. You’ll need bits with shanks that are the same size as or smaller than the chuck on your drill. Light-duty drills have a 14-inch chuck, regular drills have a 3/8-inch chuck, and heavy-duty drills have a 12-inch chuck.
Drill bits are classified into a variety of categories based on their intended function. The twist drill bit, for example, is the most popular and is used for general-purpose drilling in wood, plastic, and light metals. These heavy-duty bits, which are fashioned like an oar with a tip in the center, are used to drill big holes in wood. Brad-Point bits are for wood and make large, clean holes and are fashioned like a twist bit with a looser, larger twist.
What are the factors to consider before buying drill bits?
The work’s nature
Before you go out and buy a drill bit set, you need first to evaluate the nature of your work. Is the work mild, medium, or heavy? There are several sizes of drills, so keep this in mind while purchasing them. It is also a good idea to consider purchasing a drill with different sizes.
Make certain that the drill bit set you choose is adequate for the job. If you simply need it to hang pictures and conduct minor repairs around the house, it is not necessary to get the most costly drill set available. Similarly, as a carpenter, you will not want to purchase a low-cost drill bit set. When selecting a drill bit set, consider your degree of use.
Drill bit shape
Drill bits are widely available at most hardware stores. The most common drill bit has a twisted shaft, a tip that is inclined at around 118 degrees, and drills through most home materials. Because it can be used for so many tasks, it is popular among DIY homeowners; nevertheless, this one-size-fits-all drill bit is not the ideal choice for every project.
What is the price range of the best drill bits?
There are different types of drill bits that are available in different price ranges. Drill bits work best on the materials for which they were designed. Plastics, for example, drill better when the drill bit has a point angle of 90 degrees, but steel drills better with a tip angle of approximately 130 degrees. To drill steel or another extremely hard material properly, you frequently need to drill a starting hole. Generally, you can find drill bits in the range of $10 to $90, depending upon the construction material, brand, and other factors.
If you don’t have the appropriate drill bit, drilling through hardened steel might be tough. If you use the incorrect drill bit, the tip may bounce back or dance over the surface rather than producing a crater in the strong material. The Titanium Pilot Point drill bit set was designed by DEWALT to help with the tough task of drilling through hardened steel. Even after numerous usage, the bits are extremely robust and do not crack, freeze, or dull.

Drill Bit FAQ
Q: Is it possible to sharpen drill bits?
A: Most twist drill bits can be sharpened, which not only improves their effectiveness but also increases the safety of your drill because dull drill bits are more likely to slide or skid through hard surfaces.
Q: Is it true that drill bits are universal?
A: As a general rule, any brand of the drill bit may be used in any brand of the drill as long as the drill bits are the right size for the chuck. The component of the drill that secures the bit in place is called the chuck. 14-inch, 38-inch, and 12-inch chucks are the most common sizes. You can’t use a bit with a shank that’s longer than the chuck of your drill.
Q: What is the best way to clean drill bits?
A: If your drill bits are rusted, soak them in white vinegar for at least 30 minutes, then scrape the rust away with an old toothbrush or a metal cleaning brush. Before using or storing the bit, carefully rinse it in clean water and dry it entirely.
