| Features: |
|
1. Metric design.The special "thread milling cutter" is for cutting high-hardness materials.
|
|
2. If thread milling cutter is accidentally broken during processing, it can be taken out easily; Compare to screw tap, if the screw tap broke, it is hard to remove and even caused the workpiece to be scrapped.
|
|
3. It can process "internal thread and external thread", "left thread and right thread". The processing path can be controlled by computer program, and freely applied on the size,precision tolerance,thread depth and special aperture thread.
|
| Working Materials Hardness Level: Good at steel material (HRc 48~65). E.g. SKD61(HRc52) ,SKD11(HRc62) etc. |
Applicable Milling Methods:  Thread milling |
