Tips for Optimal Performance
To maximize the potential of your center drill bits, here are some handy tips:
1. Securely fix the workpiece in the lathe machine to prevent any wobbling during rotation, ensuring precise drilling.
2. Before drilling, ensure the surface is free from impurities. Use oil or suitable lubricants to protect the bits and enhance drilling efficiency.
3. When drilling, it is recommended to go 2/3 deep on the tapered section for optimal results.
4. Pay attention to the drilling sound. If any abnormalities occur, immediately cease drilling, address the issue, and resume after rectification.
5. Maintain cleanliness by cleaning the center drill bits before and after each use. Apply oil to store them properly, preventing rust and preserving their quality.
