The Carmex Single Threading Insert Holder SR0048M40 is a precise tool holder designed for CNC milling that accommodates carbide external and internal threading inserts. Part of the Mill-Thread family, it enables threading operations on CNC mills using helical interpolation, delivering faster cutting speeds and flexible insert options for reliable, repeatable threads. This setup helps shops boost productivity while keeping tooling costs lower than traditional taps and dies.

Designed for tough production environments, this holder features an internal coolant bore to efficiently deliver coolant directly to the cutting action, helping control heat and chip evacuation for cleaner threads and longer insert life. Built to withstand demanding milling workloads, the SR0048M40 provides stable insert seating and consistent performance across multiple threading applications.

• Internal coolant bore: Delivers targeted cooling and chip evacuation at the cut, helping maintain thread quality and reduce wear on inserts.
• Mill-Thread compatibility: Supports a broad range of carbide external and internal threading inserts, offering flexible, cost-effective tooling and easy insert swaps.
• Secure, durable clamping: Robust construction and precise alignment ensure reliable insert seating for consistent thread profiles and reduced downtime during tool changes.

In daily production, this holder helps you achieve dependable threading results with less setup fuss, faster cycle times, and lower tooling costs. It’s a practical, trusted choice for engineers, machinists, and shop managers who value steady performance and straightforward maintenance in shared milling operations.
