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 1.5xD; 2.0xD and 2.5xD.

The patented drill thread milling tool produces a complete thread, including drill hold 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
