The Carmex SR0013J14C is a long-overhang carbide shank threading insert holder designed for external and internal threading on CNC milling centers. Built for shops that need precise, repeatable thread milling with cost-efficient tooling, it delivers reliable performance across demanding operations.

• Long overhang design: overall length up to 270 mm (10.5 inches) to reach deep features while maintaining rigidity.
• Internal coolant bore: integrated coolant passage to keep the cutting zone cool and protect inserts.
• Carbide shank construction: robust, wear-resistant body tuned for high-speed threading with multi-tooth inserts.
• Supports carbide external/internal threading inserts: versatile tooling for various thread milling applications.
• Operational guidance: when machining long overhangs, reduce cutting speed and feed by 20–40% depending on workpiece material, thread pitch, and overhang length.
• Important compatibility note: SR0390K12C cannot be used with conical inserts (12-18 NPT / 12-18 NPTF / 12-19 BSPT).

This holder unlocks higher productivity in thread milling by enabling faster cutting with multi-tooth carbide inserts on CNC mills, while keeping tooling costs lower than traditional taps and dies. Its long reach is ideal for deep or recessed threads, and the integrated coolant bore supports sustained performance in heat-intensive operations. The precision-ground carbide shank delivers consistent accuracy across extended toolpaths and frequent tool changes.
