How to choose the right drill bit for your project

When you have the right drill bit, it makes life so much easier. Let’s explore the different types of drill bits and what they are designed to do.

Multipurpose drilling

These all-rounder drill bits are designed to be used across various surfaces such as soft metal, wood, plasterboard and ceramics. They are suitable for a variety of different applications and are essential to any toolbox. The most common multipurpose drill bits are:

  • Twist drill bits
  • Brad drill bits
  • High-speed steel bits
  • Step drill bits

Masonry drilling

The best masonry drill bits are designed to cut through tough surfaces such as stone and concrete. When using these types of drill bits, it’s vital to ensure you’re using the correct type of drill to get the job done effectively and efficiently. Masonry bits can be used in a standard drill; however, they are far more effective when used in a hammer drill.

Metal drilling

There are a few different types of drill bits that are best suited to drilling into metal, the most common ones are cobalt drill bits which are resistant to high temperatures and abrasion. The other is a reduced shank drill bit, which enlarges an already existing hole when used on a standard drill chuck.

Wood drilling

For the everyday DIYer, drilling into wood is probably the most common use for drill bits. The auger drill bit is widely used for woodwork and is designed to effectively drill into dry or hard wood with ease. Spade drill bits are designed to drill large holes into timber, and twist drill bits are also a popular option as they have a variety of uses when working with timber.

Screwdriver bits

These are pretty self-explanatory, flathead or phillips head screwdriver bits can be attached to a drill chuck to create a powered screwdriver. They make fast work of those flatpacks.

Best drill bit materials

Now we’ve covered the most common drill bits, let’s get stuck into the different materials that drill bits are made from and how this impacts performance.

Drill bits are made from either carbon steel or high-speed steel and can have a variety of different coatings.

Carbon steel

Low carbon steel is usually a cheaper option to manufacture and is not designed to cut through hard metals, but they are still excellent for soft wood.

High carbon steel is best used on hard materials such as wood and metal, these drill bits can keep their shape for a longer period than low carbons steel making them a more effective option.

High-speed steel (HSS)

Designed to drill through hard surfaces with maximum precision and efficiency, these drill bits are a durable solution for high volume work that involves fast and repetitive drilling. They are a popular item on the market due to their ability to withstand high temperatures while maintaining structural integrity.

Titanium coated

These drill bits are usually made from HSS with the added benefit of the titanium coating, and they can be used on both soft and hard surfaces. However, it should be noted that harder metals do wear the drill bits down faster due to the coating being removed during the drilling process.

One questions people have is are cobalt or titanium drill bits better?

Cobalt drill bits aren’t coated in cobalt as such, instead they are an alloy made with a small amount of carbon added to HSS to ensure maximum strength and a higher heating point. Cobalt has a higher melting point of around 1495 °C [1], this means a cobalt drill bit can be used on hardened materials and will maintain its sharpness for a longer period. One of the main advantages of cobalt drill bits is that they can be sharpened on a bench grinder without degrading the performance.

Tungsten Carbide

Arguably one of the most durable drill bits available, it quickly disperses heat and can go most materials. However, they are more brittle than HSS bits and can be broken up with incorrect use.

Diamond tipped

Diamond drill bits are usually reserved for drilling on materials such as porcelain, ceramic tiles, slate, marble, granite, and fibreglass. It’s important to remember that water is required for lubrication when using these drill bits.

Again, it depends on what you’re planning to drill.

Cobalt drill bits are designed to be used on tougher materials such as cast iron.

HSS bits work best for drilling into timber and other softer materials.
