Insert for metric fine threads 0.75 mm full ISO profile
The 16 ER 0.75 ISO BMA thread insert is a precision turning tool for making 0.75mm pitch metric fine threads with full ISO profile. The 16 series metric external thread insert with dedicated full profile provides complete thread forming including coil tips without the need for additional finishing.
Key benefits of the 16 ER 0.75 mm ISO BMA insert
- Full ISO profile for 0.75 mm pitch - forms a complete thread including coil tips for M4.5, M6x0.75, M7x0.75, M8x0.75, M9x0.75, M10x0.75
- Finished thread without additional machining - full-profile insert shapes the thread outline along with finishing the vertices in one operation on the lathe
- Series 16 for process stability - design provides rigidity and precision for turning fine threads
- Interchangeable use - insert works as outside legal and inside left when mounted in the appropriate Series 16 lathe holder
- Dedicated metric profile - angle of outline 60 degrees in accordance with ISO standard to ensure dimensional repeatability in series production
The insert is used in the production of precision mechanics and electronics requiring fine threads with a pitch of 0.75 mm. Ideal for workshops making parts with fine metric threads in production runs requiring high quality. Prepare the nominal diameter of the shaft before starting threading on the lathe.

Frequently asked questions
1. In which toolholders is the 16 ER 0.75 ISO BMA insert mounted?
The 16 ER 0.75 ISO insert is mounted in right-hand external lathe cut ters equipped with a 16 ER type socket. Thanks to the versatility of the design, the same insert also works with the 16 IR series left-hand internal boring tools, which allows both external and internal threads with a pitch of 0.75 mm.
2. What fine threads can be made with the 0.75 ISO insert?
The insert allows the turning of metric fine threads with a pitch of 0.75 mm: M4.5, M6x0.75, M7x0.75, M8x0.75, M9x0.75, M10x0.75 and all other metric threads having a pitch of 0.75 mm. The ISO full profile provides a complete thread finish in accordance with the international standard for fine threads.
3. What is the difference between an ISO full-profile insert and an AG60 universal insert?
The ISO full-profileinsert forms a complete thread including the tops of the coils in one operation, while the AG60 universal insert shapes only the sides of the thread. The 0.75 ISO profile is dedicated only to the 0.75mm pitch and provides a finished thread without chamfering the vertices, which increases productivity and dimensional repeatability.
4. How to calculate the height of the 0.75 mm fine thread outline?
H1 - Thread outline height given in [mm] || P - thread pitch given in [mm]
H1 [mm] = 0.6134 × P
For a thread with a pitch of 0.75 mm: H1 = 0.6134 × 0.75 = 0.46 mm
