Flow Drilling and Tapping
Precise threaded connections for thin wall applications.
Flow drilling uses heat to drill holes into metal to produce a bush. This process has always been problematic when using tubular materials as the wall is so thin particularly where a thread pitch is greater than the wall thickness. With flow drilling and tapping, the problems of tapped inserts spinning are avoided.
The DDI Engineering advantage is:
- Flow tapping removes none of the parent metal which enables us to tap into thin wall materials with a range of M3 – M12 threads.
- The bush formed gives three to four times the original material thickness in most cases.
- High quality, clean and efficient.
- Cost saving and problem solving.
- Suitable for all materials which can be friction drilled.
- Precise formation of the thread within the bush.
