These are just some of the common types of drill bits, and there are many other special-purpose drill bits, such as rock drilling bits, internal drilling bits, thread tapping bits and so on. Choosing the right type and size of drill bit according to the actual need can improve the working efficiency and drilling quality.
What are the types of drill bits
Drill bits are tools used for drilling holes, and there are many types, each with a different structure and purpose. Here are some common types of drill bits:
1. Plain Drill Bits: Also known as straight shank drill bits, they are the most common type of drill bit. They are usually made of high speed steel (HSS) and are suitable for drilling materials such as wood, plastics, aluminium and light metals.
2. Boring Bits: Suitable for drilling larger sized holes. They are usually made of HSS or carbide and can be used to machine metals and plastics with larger drilled internal diameters.
3. drilling cutters: also known as flat drills or woodworking drills, have a flat drill shape. They are mainly used for holes and hole edges in woodworking and carpentry.
4. Centre drills: are usually used to mark the centre point of holes in a workpiece for subsequent positioning. They are usually made of high speed steel and have a sharp centre drill bit.
5. Glass Drill Bits: Specially designed for drilling fragile materials such as glass, ceramics and tiles. They are usually made of carbide and have a sharp cutting edge.
6. parquet drill bits: used for making fine items such as jewellery and metal crafts. They are usually made of high speed steel or carbide and have sharp and tiny cutting surfaces.
7. Nail Drill Bits: with a special bit design, they are used to pre-drill holes to avoid splitting of wood in construction and furniture making.
8. deep hole drills: suitable for drilling holes of greater depth, often with special cutting geometry and coolant channels to improve heat dissipation and chip removal.
9. Shackle Drill Bits: Special drills with adjustable diameters that can be used to drill holes of different diameters, typically used in woodworking and metalworking.
10. Drill Bit Sets: Contain several different types and sizes of drill bits for different job requirements.
These are just some of the common types of drill bits, and there are many other special-purpose drill bits, such as rock drilling bits, internal drilling bits, thread tapping bits and so on. Choosing the right type and size of drill bit according to the actual need can improve the working efficiency and drilling quality.
