Drill bits are cutting tools that people can use to make holes. They can use almost any bit to drill on soft materials. The real challenges come when it comes to drilling on a brittle or hard material such as acrylic, glass, wood etc. In a situation like this, people need to choose their bits very carefully. Continue reading to know all the information about bits and know about their different types and uses.
Overview
A drill, in general, is nothing but a cutting tool that people can use to remove materials from a surface in order to create holes. Bits mainly create holes in circular cross-section. They come in different sizes and shapes. People use different types of bits to create different types of holes on different types of materials. So when it comes to creating a specific type of hole, you have to be really careful while choosing the right type of bits.
If you look around, then you will find several hardware stores that sell different types of hardware tools and workwear. Apart from just nuts, bolts, cat workwear, stainless steel products, they also offer some other types of hardware tools such as drill bits.
Materials and Coatings
A drill bit can be made of several things such as carbon steel, cobalt steel, solid carbide, carbide tips or tool steel. Manufacturers can also use high-speed steel or HSS to build bits. Developing the shape of the bits is only half the job. In addition to that, they also have to apply a coating on it.
Black oxide is the most popular type of material that can be used as a coating. This is also an economical solution that protects the bit from corrosion. Black oxide coated bits are recommended to use on iron and steel. However, one can also use them on magnesium, aluminium or other similar materials.
Titanium Nitride or TiN is another popular solution that you can use for coating. TiN coating is an expensive option, but it makes the bit much more durable. One can use TiN-coated bits on steel as well as on magnesium and aluminium. Bronze oxide is another solution for coating. People who want to drill on steel can consider opting for this coating.
Types
Drill bits are available in many different types. Check out here their different types and know about their uses.
- Plug cutter is a popular type of bit that one uses to cut round plugs. People generally take the measurement of plug cutters from their inside diameter.
- People who want to create a round hole in brick and concrete should consider using masonry drill bits. Masonry bits generally come with black oxide coating. So people can also use them to create holes on steel.
- People who want to drill on the glass should consider using glass and tile drills.
This is all about bits. Hope the post was helpful and it will help you to choose the right type of bits for addressing your drilling needs.
