Drill Bits Buying Guide
Drill Bit Materials
There are many different types of materials that are used to make drill bits. We have listed the different types of materials below and a little about what they are suited for.
- Steel – Steel drill bits are some of the most inexpensive types of drill bits available but when used to drill into hardwood or harder materials they can dull very quickly. They are terrific for drilling holes into softwoods.
- High Speed – High speed bits stay sharp for a lot longer than plain steel bits. They are also harder than steel and are excellent for general purpose drilling projects.
- Black Oxide – Going on up the hardness and durability ladder is black oxide drill bits. These are two times more durable than high speed drill bits and are also used for many different applications.
- Titanium – Titanium drill bits are very popular and are more durable than both steel and high speed drill bits.
- Titanium coated – these drill bits are as much as six times more durable than high speed bits. They are more expensive and feature reduced friction for cooler drilling which is a plus.
- Carbide Tipped – These durable and long lasting drill bits are harder than titanium, steel and high speed bits and make excellent drill bits for a number of different applications.
- Zirconium coated – users will find that these drill bits provide much less friction and improved durability along with a smooth finish that is very hard.
- Cobalt – Cobalt drill bits are high quality bits that get rid of friction from drilling quickly. They are extremely hard and can be used to drill into stainless steel as well as other metals. They are long lasting and durable as well.
Types of Drill Bits
Now that you understand about drill bit materials, we will provide information about the different types of drill bits that are available. It helps to understand what you want to do with your drill and how often it will be used. Those determining factors help users choose the bits that will be able to stand up to the demands they place on them.
With so many different types of drill bits on the market, it is beneficial to the driller to choose a variety of bits that can work with many different materials. If you work heavily with one specific type of material such as metal or wood, it would be a lot better for your project outcomes to choose a couple of different types of drill bits. We have listed the different types of drill bits below.
- Universal – Universal drill bits are perfect for drillers that have a lot of different types of projects that they work on. This type of bit can be used for drilling in metal, plastic, wood and other materials too. A few different types of universal drill bits include:
- Twist drill bits
- Step drill bits
- Metal – Metal drill bits are better for metal applications because even though universal bits will work, they don’t do well for repeated use on metal projects. This type of bit is much harder than the universal bits and usually has a specific drilling purpose. Different types of metal drilling bits include:
- Center bits
- Spotting drill bits
- Wood Drill Bits – Drill bits that are designed for drilling into wood can usually be made from softer metals. They are designed to drill into wood better than other types of bits due to the tips and flutes that are made specifically for wood. There is hardwood and softwood that people use for projects. Not all bits can be used for hardwood. Make sure you look for the right bit for the project and even if it is a wood drill bit, make sure it can handle drilling into hardwood. Different types of wood drill bits include:
- Lip and spur bits
- Wood spade bits
- Spoon bits
- Forstner bits
- Auger bits
There is a lot more to finding the right set of drill bits than one might realize. If you have a lot of experience using drills you are already familiar with the large array of choices available. If you are relatively new to the drilling world, it can be really overwhelming when you see just how many different kinds, sizes, types, materials and applications that are available when it comes to drill bits.
Drill bits are designed for drilling into metals, woods, plastics and many other materials including concrete. Having the right drill bits for the project you are working on prevents you from breaking the drill bits you are using (if you are using an incorrect type for the project) and helps the drilling process go much smoother.
Drill bits can be purchased separately or in sets like the three featured drill bit sets above. Most drillers will buy at least one good quality set of drill bits and then if they need specialty bits they can purchase those as the projects dictate.
If you routinely work with different materials such as wood, metal and plastics, you may want to consider purchasing a couple of different drill bit sets that will work the best with the different materials you work with. It will make the drilling process much simpler, smoother and more enjoyable when you have exactly the right drill bit for what you are working on.
