Carmex Carbide Threading Insert - NPS - TiAlN Coated - 21-11.5NPS

Introducing the Carmex Carbide Threading Insert - NPS - TiAlN Coated - 21-11.5NPS. This durable carbide insert is designed for machinists who routinely work with common thread profiles, delivering dependable performance across a range of applications.

• Double‑edged cutting edges: Each insert provides two ready-to-use edges (except for BSPT/NPT/NPTF/American Buttress/API RD variants), delivering extended life before reindexing is required.
• Broad thread profile coverage: A versatile collection that accommodates all the common thread profiles you’re likely to encounter in everyday machining.
• Five length options: Available in 12 mm to 40 mm lengths, giving you flexibility to match your tooling setup and depth of cut needs.
• Pitch range (depends on length): Compatible with pitches from 0.5 mm / 32 TPI up to 6.0 mm / 4 TPI, depending on the inserted length for optimal performance.
• TiAlN coating: The TiAlN layer enhances wear resistance and contributes to longer insert life in demanding materials and high-speed threading jobs.
• Carbide construction: Precision-ground carbide construction delivers consistent cutting action and repeatable thread forms.
• Internal & external threading versatility: For many thread profiles, the same insert can machine both internal and external threads, reducing tool changes (note: ISO / UN / NPSM / UNJ / Acme profiles may require specific considerations).

This carbide threading insert is built to support efficient, accurate threading across a broad spectrum of projects, from hydraulic fittings to general pipe-threading tasks. The combination of multiple lengths, dual cutting edges, and TiAlN coating helps you reduce downtime, improve tool life, and achieve reliable thread quality with less tuning between jobs.
