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

Carmex Carbide Threading Inserts in a TiAlN coating deliver precise, durable threading across a wide range of common profiles. Built for machinists who need reliable internal or external threads with long tool life, these inserts are designed to perform in demanding turning applications.

• Coating: TiAlN-coated carbide for enhanced hardness, wear resistance, and heat tolerance, helping maintain sharpness and finish in tough materials.
• Cutting edges: Double-sided inserts with two cutting edges (except for BSPT/NPT/NPTF, American Buttress, and API RD profiles) to extend usable life between reindexes.
• Internal/External versatility: For many thread profiles, the same insert can machine both internal and external threads (excluding ISO/UN/NPSM/UNJ/Acme).
• Profile coverage: A versatile collection that covers all common thread profiles, reducing the need for multiple tools.
• Lengths: Five available lengths, ranging from 12 mm to 40 mm, to suit different machine setups and clearance requirements.
• Pitch range: Supports pitches from 0.5 mm (32 TPI) to 6.0 mm (4 TPI), accommodating a broad spectrum of standards.

With these carbide inserts, you can achieve consistent thread quality, minimize tool changes, and extend cycle efficiency across diverse threading tasks. The double-edged design and TiAlN coating work together to deliver reliable performance for everyday threading needs and more challenging materials.
