Meet the Carmex Deep Reach Mill Thread Holder SR0025D21-1S — a precision tool holder designed for CNC milling threading tasks using carbide inserts. Built for shops and engineers performing high-speed thread milling with helical interpolation, it delivers deep reach with a stable, repeatable interface.

• Two-threading-insert system: Uses two carbide threading inserts to boost productivity and shorten threading cycle times on milling operations.
• Internal coolant bore: Integrated coolant channel directs fluid to the cutting zone for efficient cooling and chip control, helping extend insert life.
• Deep reach / long projection: Optimized geometry provides extended reach into recessed or hard-to-access threaded areas while maintaining rigidity.
• Carbide inserts compatibility: Designed to work with external and internal carbide threading inserts for durable, precise cuts.
• Indexable design (SR0025D21-1S series): Reliable, replaceable inserts and a sturdy interface that preserve tolerances across production runs.

This thread milling solution streamlines CNC threading work, leveraging a dual-insert system and carbide inserts to enable higher cutting speeds. It also offers a cost advantage by reducing tooling expenses relative to taps and dies. The internal coolant bore supports longer tool life and better surface finish during extended threading passes.
