Drilling, chamfering and thread milling in a single pass.
The BGF drill thread milling tool rear chamfer is a standard tool for defined thread lengths of 1.5×D; 2.0×D and 2.5×D.
The patented drill thread milling tool produces a complete thread, including drill hole and chamfer, in a single pass.
This offers the following main advantages compared to the conventional methods of tapping and roll form tapping:
- Only one tool instead of 2 or 3
- Shorter cycle times
- One and the same tool for blind and through holes
- One and the same tool for different materials
- Exact and repeatable drill and thread depth from 1st to last thread
- No chip root remaining in the thread
- High speed cutting (HSC) possible
