Comparison table by different materal of the pipes
- Brass:
- Easy to handle with its flexibility. Pipe may consume faster depending on the material of the workpiece.
- Copper:
- Copper is most commonly used. Pipes and coreless types are available. Economical and sufficient for deep hole drilling and continuous machining.
- Copper Tungsten:
- For precision and carbide machining.
