How does it work?

These bits will be helpful when you need different sizes of holes with varying diameters, as these allow you to adjust themselves accordingly. This way, the need to get separate bits is minimized.

Annular bits will not only drill holes into distinct materials, but these bits will also let you extract the core.

Auger bits are known to be smooth and require lesser pressure than most of the drill bits; because of a screw-thread tip, only minimal effort is needed to work with it. You can easily use it on thick and dry wood to drill comparatively large holes. It consists of a hexagonal shank that further strengthens the grip.

These bits come with rubber stoppers to ensure a desired depth of holes into the surface. The brad point bits will also create precise and cleaner holes compared to other drill bits.

For cleaner holes, go for the bullet point bits, as you can use them for plastic, wood, and metal.

Counterbore drill bits are used for enlarging an already existing hole to make the screw stand firmly at its position. The counterbore drills a hole of the same length as the screw upto the screw head.

A countersink drill bit is also commonly called a screw pilot bit. It is used for drilling into the wood and can also drill pilot, countersink, and counterbore holes simultaneously.

Flat boring bits will be a lifesaver when you want holes with flat bottoms. They will drill holes of the desired type and shear material as you are drilling through it, making it possible to have a smoothly finished hole. These bits can also be used for counterboring holes, producing half and intersecting holes as well as holes at an angle.

For smooth, clean, and accurate holes in wood, go for the Forstner bits, as these also come with a pointed tip that will let you control the positions.

Glass and tile bits will work perfectly with any material, be it tile, glass, marble, or brick. In addition to that, they can also bear high temperatures as well.

For an accurate and precise hole in a concrete slab, hammer bits will prove out to be essential drill bits, along with finding out the humidity level in that material.

High-speed bits are formed with vanadium and tungsten elements which is the main reason behind their exceptional strength. These perform effectively when used for steel drilling or other general purposes. You probably know these as twist drill bits as this is what they are commonly known as, due to their cylindrical shank and the fact that you can use them for almost anything.

If you are going to create a wiring pass-through or put up door hardware, then a hole saw would be a good choice for starting your project. The hole saw will form a waste plug which a saw cylinder will then push out.

The installer bits come with a different purpose for installing wirings for security and entertainment. They are also uniquely shaped as they have a tip.

Masonry bits are a great option if you want to drill into tough surfaces like concrete, mortar, bricks, and stone. Their toughness is due to the Tungsten carbide tipped at the top of the drill bit. It becomes easier to identify these bis as their tip is wider than the shank. However, as much as they are hard, they wear out quickly. For this reason, you will need to change the bits more often. You can drill with a masonry bit a maximum of 400 mm as their sizes range from 4 to 16 mm.

One drawback while working with one of these bits is that they tend to heat up quickly. It happens when the tungsten coating on the tip melts, generating enough heat. To solve this problem, it’s essential to keep cold water nearby and dip the drill now and then before drilling.

A plug cutter is used explicitly for drilling into wooden surfaces and when you want to cut out a plug or make a hole in any wooden material.

Professionals use the rivet bits mainly because of their unique ability to drill short and precise rivets into thin sheets of metal plates.

These bits consist of a tip that will stay in the countersunk hole, placing itself along the center. After pressurizing a bit, the bits will make their way into the material. The self-centering bits are used for creating hinges in wood and other similar materials.

Self-feed bits comprise a screw at the tip that helps position the bit accurately and produces a precisely clean result. However, while working with these bits, you will have to stop at regular intervals in order to wipe the dust away,

As the name suggests, spade bits are shaped like a spade to cut through holes into softwood. Primarily, these bits are used for boring holes in running cables.

Step bits are primarily shaped as a series of pyramid steps used to drill holes of differing thickness across the metal sheets. The step bits are the go-to bits because of their flexibility.

These bits are tipped with a carbide that ensures crack-free drilling into the tiles. However, before purchasing these bits keep in mind that each tile bit works for different tiles, so make sure to check the packaging beforehand.

Twist bits are one of the most used drill bits out there as anyone can utilize them, be it a regular craftsperson or a professional. These bits can do a great job drilling through wood, plastic, steel, and even concrete. They are mostly known to be great performers when cutting metal.
