The Carmex Twin Threading Insert Holder SR0020H14-2 is a versatile, indexable tool holder designed for carbide external and internal threading on CNC milling machines. Its twin-insert configuration lets you perform threading with two inserts in a single setup, delivering stable, repeatable results across a wide range of threading tasks.

This solution is ideal for machine shops, engineers, and craftsmen who need fast, reliable threading with minimal tool changes. By combining higher cutting speeds with durable, multi-tooth carbide inserts, it provides efficient, economical threading performance that can reduce overall tooling costs compared with traditional taps and dies.

• Twin-insert configuration for higher productivity: Two threading inserts in one holder enable parallel cutting and faster cycle times for both external and internal threading, boosting throughput and reducing setup time.
• Internal coolant bore: Integrated coolant passage delivers coolant directly to the cutting edge, improving chip control, cooling efficiency, and insert life for cleaner, more consistent threads.
• Cost-effective carbide tooling: Multi-tooth carbide inserts paired with a two-insert design offer durable, long-lasting performance at a lower tooling cost than taps and dies, helping you lower per-thread production costs.

By leveraging this holder and its twin-insert design, you can streamline threading workflows on CNC mills, achieve consistent thread quality, and reduce downtime from tool changes, all while maintaining strong performance across demanding threading applications.
