Carmex Carbide Threading Insert - Whitworth - TiAlN Coated - 21-14W

Carmex Carbide Threading Insert - Whitworth - TiAlN Coated - 21-14W is a versatile carbide threading solution built for machinists who routinely cut Whitworth and other common thread forms. This TiAlN-coated insert delivers reliable performance across a range of pitches, with multiple cutting edges designed for efficiency and longevity.

• Thread profiles covered: A comprehensive set that handles all common thread profiles, including Whitworth, with pitches from 0.5 mm (32 TPI) up to 6.0 mm (4 TPI) depending on length.
• Length options: Five lengths ranging from 12 mm to 40 mm to fit a variety of tool holders and workpiece sizes.
• Double-sided cutting edges: Each insert provides two cutting edges for extended life and reduced downtime (except BSPT/NPT/NPTF/American Buttress/API RD).
• Internal & external threading capability: For many thread profiles, the same insert can machine both internal and external threads (note exceptions: ISO/UN/NPSM/UNJ/Acme).
• TiAlN coating: TiAlN coating enhances wear resistance and thermal stability to extend insert life in demanding materials.

Designed for precise, repeatable thread production on lathes and turning centers, the 21-14W insert provides dependable performance across a range of Whitworth and standard metric profiles. The combination of multiple edges, varied lengths, and a robust TiAlN coating helps you reduce tool changes, improve consistency, and achieve higher-quality threads in everyday manufacturing and retrofit applications.
