The Carmex Single Long Shank Threading Insert Holder is a precision tool designed for CNC milling threading tasks. It supports carbide external and internal threading inserts and is ideal for engineers, buyers, tradespeople, hobbyists, and non-technical customers who need reliable, repeatable threads on modern milling centers.

Built for long overhang applications, this holder helps you reach deep thread features with a robust, rigid design. It features an internal coolant bore and comes in metric versions up to 210 mm (and inch versions up to 6 inches). When machining long overhang jobs, reduce cutting speed and feed rate by 20–40% (the exact value depends on workpiece material, thread pitch, and amount of overhang).

• Long overhang design for deep threading: Enables access to extended thread features with maintained rigidity, improving consistency on challenging geometries.
• Internal coolant bore for direct cooling: Delivers coolant straight to the cutting edge, enhancing chip control and tool life during sustained threading passes.
• Carbide insert compatibility for faster, cost‑effective threading: Works with multi-tooth carbide inserts to boost productivity and reduce tooling costs compared with traditional taps and dies.

This holder helps you complete threaded features more efficiently, reach hard-to-access areas without frequent tool changes, and maintain consistent thread quality across runs. By enabling direct coolant delivery and compatible carbide inserts, it supports higher cutting speeds where appropriate while helping to manage heat and wear. The result is a streamlined workflow, lower operational costs, and reliable performance across a wide range of CNC threading tasks.
