Your hammer and rotary drill will be worthless if you don’t understand the many sorts of drill bits. These durable boring heads are made for specific applications, drill forms, and base materials.

You risk snapping your drill bit, damaging your target medium, or even wrecking your power tool if you use the improper drill bit type. Drills are useful equipment for everyone, from amateur crafters to professionals.

However, it is critical that you use a suitable drill bit to avoid damaging the material you are drilling into. The most commonly used drill bits and their applications are listed below. Continue reading to get the best drill bit for your job.

What is used in Drill Bit Manufacturing?

Drill bits are manufactured of various materials depending on their intended use. Choosing the correct bit material improves your productivity. These drill bits are sometimes made of a cobalt and HSS alloy.

What are all the different types of drill bits?

Drill bits have various types. We’ll go over some to help you understand them better:

Brad Point:

Without a doubt, the greatest drill bits for wood. These timber maestros deliver crisp holes into wood and reduce the risk of splintering or splitting, distinguishing themselves from the twist format by their distinctive W-shaped heads.

In practice, the point of the ‘W’ enters the wood for precision and dependable anchoring.

Twist or Standard Drill Bit:

If your interactions usually concentrate around power tools, this is what most people think of when the words “drill bit” are discussed.

The twist bit uses a basic screw structure and has dual cutting blades at the tip, as well as dual grooves, which pull the swarf away from your target material. They’re the go-to all-rounder for the DIYer or trade pro since they’re versatile, multi-medium, and multi-drill format compatible.

Auger Bit:

If the brad bit isn’t cutting it for your wood items, you’ll need an auger. Auger bits are the mother of all monster wood drill bit types and are employed for major woodworking operations that need huge holes or are required to deal with thick woods. A screw head on the bit’s business end conducts the first wood penetration.


The spade bit is the go-to boring attachment for pipe and wire channeling out of all the many types of drill bits.

They, like the auger bit, have a screw head tip for the precision and convenience of drilling, but they leave a sloppy finish. As a result, they’re usually used in places where beautiful aesthetics aren’t required.


It is a unique woodworking tool. Countersink bits provide a small borehole with a larger aperture at the material surface, as the name implies.

This allows trained artisans and cabinet builders to recess screws or bolts flush with the wood surface, resulting in a neat and snag-free finish. They may be used with any rotary machine; however, we recommend using a pedestal drill for perfect aesthetic precision.

Installer Bit:

The installation bit has to be the most unique of all the drill bit varieties and applications. As the name implies, this drill accessory is being used to install thin wire in safety systems, CCTV, and sound home leisure.

These borers will puncture plaster, timber, as well as semi-dense masonry and available in a range of sizes up to 18 inches. This allows you to cleanly slip difficult electrical wiring through even the tiniest openings.

Tile Bit:

For the home DIYer or trade professional, drilling into tiles might be one of the most difficult undertakings. When drilling a hole, these carbide-tipped cutting heads lessen the danger of chipping, cracking, and shattering ceramic and porcelain tiles.

They may potentially be used with any rotary drill and are essential for kitchen and bathroom chores, such as changing showerheads or installing soap dispensers.

Maintenance of Drill Bits:

As a responsible DIYer or tradesperson, you understand the importance of properly maintaining your tools, including drill bits.

For extended periods of time, they are pushed, sheared, punched, as well as hammered, subjected to harsh and degrading substances, or exposed to exceptionally high friction-generated warmth. If you don’t take care of your parts, they’ll get dull and brittle.

Not only will you be unable to complete your job, but you may also damage your drill, target material or even get an accident. Here are some of my drill bit maintenance recommendations:

  • Sharpen on a regular basis with a grinder or sharpening tool.
  • Keep your drill bits secure by using the case or sheath that came with them.
  • Make sure the bit will work with your drill and chuck size/style.
  • After each usage, clean the bit.
  • Regularly apply oil to avoid rusting.
  • Inspect drill bits for wear and tear on a regular basis.
  • Keep your drill bits somewhere cold and dry.
  • Use fast speeds for soft materials and moderate rates for thick media to avoid overworking the bit.
  • On tough materials, use cutting fluid.
  • Always keep the bit 90 degrees away from the base medium.
