The Carmex Carbide Threading Insert for ACME with TiAlN coating is a versatile, double‑edged solution designed to cover the most common thread profiles with a single tool family. Built for machinists and production shops, it delivers reliable performance across a range of threading tasks.
- Coating: TiAlN coating enhances wear resistance and high‑temperature performance for longer tool life in demanding materials.
- Five length options: Available in 12 mm, 16 mm, 22 mm, 27 mm, and 40 mm lengths to suit different workpiece sizes and depths of cut.
- Thread pitches covered: Suitable for pitches from 0.5 mm (32 TPI) up to 6.0 mm (4 TPI), enabling a wide range of ACME and common thread profiles.
- Double‑sided cutting edges: Each insert provides two cutting edges (except for BSPT/NPT/NPTF/American Buttress/API RD profiles), maximizing usable life between changes.
- Internal & external threading: For many profiles, the same insert can machine both internal and external threads, improving efficiency (note: certain profiles like ISO/UN/NPSM/UNJ/Acme have specialized considerations).
- Compatibility: Designed to work with standard Carmex thread turning holders, ensuring straightforward setup and reliable performance.
- Material: Solid carbide base for rigidity and precision in metal cutting, paired with a protective TiAlN coating for longevity.
This threading insert is an all‑around workhorse for ACME and other common thread tasks, reducing tool changes and keeping a consistent thread finish across jobs. The TiAlN coating and carbide construction help sustain productivity when threading stainless steels and other challenging materials, while the dual cutting edges and multiple length options provide flexible, efficient machining across a variety of parts and depths.
