The Carmex SR0015K14C is a single long carbide shank threading insert holder designed for carbide external and internal threading inserts, ideal for CNC milling with helical interpolation. It provides extended reach without sacrificing precision or budget.

• Internal coolant bore: Delivers coolant directly to the cutting edge for efficient chip control and extended tool life.
• Long overhang design: Engineered to provide an efficient, cost-effective solution when a long reach is required.
• Maximum length: Overall holder length up to 270 mm (10.5 inches) for metric and inch versions.
• Versatile threading inserts compatibility: Supports carbide external and internal threading inserts for flexible threading operations.
• Operational guidance: When machining long overhangs, reduce cutting speed and feed rate by 20–40% depending on workpiece material, thread pitch, and overhang.
• Compatibility note: SR0390K12C can’t be used with conical inserts: 12-18 NPT / 12-18 NPTF / 12-19 BSPT.

Designed to boost productivity and reduce tooling costs, this holder enables faster thread milling on CNC mills while preserving precision. The robust carbide shank and integrated coolant pathway help maintain consistent performance across long overhang applications, making it a reliable choice for shops performing frequent external and internal threading with carbide inserts.
