The Carmex Deep Reach Mill Thread Holder SR0020C14-2S is a precision threading solution designed for CNC milling centers. Built to work with carbide external and internal threading inserts, it delivers reliable, high‑speed performance for demanding threading tasks.

  • Model / compatibility: SR0020C14-2S designed to pair with two threading inserts for efficient two‑cut threading on CNC mills.
  • Two‑insert design: Uses two indexable threading inserts to boost productivity and reduce cycle times on threading operations.
  • Internal coolant bore: Integrated coolant channel enhances chip evacuation and keeps cutting edges cooler for longer insert life.
  • Deep reach geometry: Extended reach allows threading in recessed features and hard‑to‑access pockets without compromising accuracy.
  • Indexable tooling strategy: Part of Carmex’s indexable thread milling family, enabling quick insert changes and reuse across jobs.
  • Applications: Optimized for CNC milling with helical interpolation to produce precise internal and external threads with smooth finishes.
  • Cost efficiency: A cost‑effective alternative to taps and dies, delivering consistent thread quality with replaceable carbide inserts.

This Deep Reach Thread Holder helps machinists achieve higher throughput without sacrificing precision. The two‑insert configuration, combined with an internal coolant bore, supports faster material removal and extended insert life, even on challenging materials. Ideal for shops performing frequent threaded features on aluminum, stainless steel, and other alloys, it pairs seamlessly with standard CNC workflows and helical interpolation programming to deliver reliable, repeatable results across a range of thread sizes.
