Key Product Advantages
Optimized micro tooling geometry provides stable access to restricted internal features and small-diameter bores where conventional tools may have limited accessibility.
High rigidity carbide construction helps reduce vibration and maintain stable cutting performance during precision internal threading operations.
Precision-ground cutting edges support accurate 55° and 60° thread profiles with consistent thread quality and repeatable machining results.
Designed for CNC production environments requiring stable performance, consistent quality and long-term machining reliability.
Why Choose MIR/MIL Micro Internal Threading Bars
| Recurso | Conventional Tools | MIR/MIL Solution |
|---|---|---|
| Rigidez | Lower rigidity may increase vibration during small-bore threading. | Solid carbide body improves stability and vibration control. |
| Controle de chip | Poor chip evacuation may affect thread surface quality. | Optimized cutting geometry supports smoother chip evacuation. |
| Thread Accuracy | Cutting instability may affect thread consistency. | Precision-ground edges maintain accurate thread profiles. |
