Carmex Carbide Threading Insert - NPTF - TiAlN Coated - 30-11.5NPTF

The Carmex Carbide Threading Insert for NPTF with TiAlN coating is a versatile threading tool designed for machinists and shops that regularly work with pipe threads and precision fasteners. It delivers reliable performance across common thread profiles with durable, long-lasting cutting edges.

• TiAlN coating: TiAlN-coated carbide for superior wear resistance and heat tolerance, helping extend tool life in demanding threading operations.
• Five length options: Available in 12 mm, 16 mm, 20 mm, 30 mm, and 40 mm lengths to suit different depths and access requirements.
• Broad thread profile coverage: Designed to cover all common thread profiles, reducing the need for multiple inserts in your toolbox.
• Double-sided cutting edges: Each insert has two cutting edges for extended use and fewer tool changes (except for BSPT/NPT/NPTF/American Buttress/API RD variants).
• Internal & external threading capability: For many thread profiles, the same insert can machine both internal and external threads, simplifying setup and inventory (except ISO/UN/NPSM/UNJ/Acme).
• NPTF-focused design: Optimized for NPTF applications to produce accurate, repeatable pipe-thread results.

This insert is built to improve workflow in threading tasks—from creating precise internal tapped holes to external shafts and pipe fittings. The TiAlN coating helps maintain edge integrity under higher cutting speeds, while the dual-edge geometry reduces downtime by allowing multiple usable edges before reindexing. With five length options and a broad range of pitches (0.5 mm / 32 TPI up to 6.0 mm / 4 TPI), it supports a wide variety of projects, helping you complete jobs faster with consistent thread quality.
