201 Drill Bit: Understanding Its Purpose and Applications
Overview of 201 Drill Bit
A 201 drill bit is a type of drill bit specifically designed for drilling precise holes in various materials, including metal, wood, and plastic. The "201" designation refers to the drill bit's diameter, which is 0.0201 inches or approximately 0.51 mm. This small diameter allows for drilling tiny holes with high accuracy, making it an essential tool for various industries and applications.
Key Features of 201 Drill Bit
- Diameter: 0.0201 inches (0.51 mm)
- Material: Typically made from high-speed steel (HSS) or tungsten carbide (TC)
- Coating: Optional coatings, such as titanium nitride (TiN), can enhance wear resistance and reduce friction
- Point angle: 118° or 135°, depending on the application
- ** Shank type:** Straight shank or hex shank
Applications of 201 Drill Bit
The 201 drill bit is widely used in various industries, including:
Electronics and PCB Manufacturing
- Drilling precise holes for electronic components, such as capacitors, resistors, and ICs
- Creating holes for wire bonding and micro-connections
