The right set of tools is very helpful in creating the desired outcomes. Every contractor investing in good quality tools is paramount; one such most commonly used tool is a drill bit. These are cutting tools used to create holes like a circular cross-section. Such tools are available in different sizes and shapes, and based on your project requirement, you can pick the right. Carbide drill bits are one such type; there are several other variations in its type. In this blog, we will discuss different materials that go into the making of drill bits and their key features. Drill bits terms in a wide range of shapes, sizes and cottages.
Common Material Used for Making Drill Bits
The drill bits are designed for specific tasks and must be chosen accordingly. Here is a quick overview of the same:
#1. High-Speed Steel (HSS): steel is by far the most preferred choice. This is also considered a good material for drilling. The high speed still drill bits are perfect for drilling through wood and plastics. It is cheap and also doesn’t require too much maintenance.
#2. Cobalt (HSCO): It is another popular choice for drill bit is cobalt drill. These ones are better than this as it has 5 to 8% cobalt mixed with the base material. Drill bits are a good option if you have to drill through harder surfaces like steel cobalt.
#3. Carbide (Carb): These are the best quality drill bits and are used where high-quality tool holder and equipment are used. Carbide drill bits are much in demand because they are used for drilling through the hardest of materials, thus simplifying the task.
Design Point Angle
As much as it is important to choose the right material of drill bits, it is equally important to know the right angle to ensure flawless results. The drill point angle emphasizes the angle at which you should be placing the drill bit to get the desired result.
- 118° Standard — this is the most common type of drill type.
- 135° Self-Cantering — this is usually used in the case of stainless steel material.
Drill Point Coatings
As mentioned, the drill bits are available in different materials and coatings. We have already talked about carbide drill bits, cobalt drill bits, and steel drill bits. Let’s discuss the drill point coatings which are available on the market.
#1. Black Oxide: It helps reduce the friction and thus increases the chip flow; however, this match this drill bit is not suitable for non-ferrous material. These are good for plastic goods and aluminum drilling.
#2. TiN (Titanium Nitride, Gold Colour): This one comes in a golden colour. This works faster than the uncoated ones and increases the drill bits’ life.
#3. TiC (Titanium Carbonitride, Blue-Grey Colour): If you are looking for a drill bit for drilling through stainless steel or aluminum, then the titanium Carbon nitride coating drill bit is a good option. These are harder and wear-resistant.
Eventually, choosing the right drill bit is an important part of any project or work. As a common man, you made might not be aware of it, and hence it’s important to look for a Workman who has a complete idea about the use of different types of tools for different purposes. Failing to do so, you may not get the desired result. Also when you decide to choose the carbide drill bits for work wear steel drill bit footwork, then you might not get the desired outcome. The right type of drill bit eventually impacts the proto work productivity, and hence it’s always important to understand the project requirement and then make the choices.
