The Carmex Twin Threading Insert Holder (SR0040L30-2) is a precision tool holder designed for CNC milling threading tasks. It accepts two carbide threading inserts, enabling efficient external and internal thread milling with high-speed cutting and consistent results.
Designed for use with helical interpolation programs, this indexable threading solution boosts productivity by leveraging additional cutting edges and fast cycles, while helping to lower tooling costs compared with traditional taps and dies.
- Twin-Insert Threading Design: Two threading inserts per holder provide more cutting edges in contact with the workpiece, increasing material removal and reducing cycle times for both internal and external threads.
- Internal Coolant Bore: Coolant through the tool improves heat management, enhances chip evacuation, and extends insert life for cleaner finishes on a range of materials.
- Cost-Effective, Versatile Solution: Compatible with carbide threading inserts and priced to reduce tooling expenses, offering a practical, high-volume threading option for CNC milling workflows.
Together, these features deliver a smooth, reliable threading process that supports faster production, consistent thread quality, and lower overall tooling costs. The holder’s robust design and twin-insert configuration help maintain performance across different materials and thread sizes, giving you confidence to meet tight deadlines with repeatable results.
