Carmex Carbide Threading Insert - ISO/METRIC - TiAlN Coated - 40I5.5ISO

Meet the Carmex Carbide Threading Insert (ISO/METRIC, TiAlN coated) — a versatile threading solution designed for metalworking professionals who need reliable performance across common thread profiles. The 40I5.5ISO designation represents a robust insert set that covers a wide range of pitches and applications.

• Five length options: available from 12 mm up to 40 mm to match your depth, reach, and setup.
• Wide pitch range: depending on length, capable of threads from 0.5 mm / 32 TPI to 6.0 mm / 4 TPI.
• TiAlN coating: carbide substrate with TiAlN coating for enhanced wear resistance and heat management during high-speed threading.
• Double-edged design: inserts are two-cutting-edge by default, extending edge life (note: BSPT/NPT/NPTF/American Buttress/API RD are exceptions).
• Internal & external capabilities: for many thread profiles, the same insert can machine both internal and external threads (excluding ISO/UN/NPSM/UNJ/Acme).
• Carbide construction: rigid, precise performance that holds tolerance across demanding threading tasks.

This threading insert is ideal for shops performing a mix of ISO and metric threads, from lightweight components to more demanding fittings. Its multi-length design and dual-edge geometry reduce tool changes and maintenance downtime, while the TiAlN coating helps sustain performance under elevated cutting speeds and temperatures. Use it for general-purpose threading on a variety of metal parts, including hydraulic fittings, fasteners, and precision components where consistent thread form and finish matter.
