Description

The Carmex Carbide Threading Insert for Whitworth threading (TiAlN coated, 14-19W) is a versatile cutting solution designed for machinists who regularly work with standard thread profiles. Built for durability and precision, it delivers reliable performance across a range of pitches and applications.

  • Thread profiles covered: Versatile inserts that handle all common thread profiles, including Whitworth.
  • Five length options: Available in five lengths from 12 mm up to 40 mm to fit various tools and setups.
  • Double-sided cutting edges: Each insert provides two cutting edges for extended life (except for BSPT/NPT/NPTF/American Buttress/API RD).
  • Internal & external threading: In many profiles, the same insert can machine both internal and external threads (exceptions: ISO/UN/NPSM/UNJ/Acme).
  • TiAlN coating: Titanium aluminum nitride coating enhances wear resistance and heat tolerance for longer insert life.
  • Pitch range: Suits pitches from 0.5 mm (32 TPI) to 6.0 mm (4 TPI), covering a broad set of standards.
  • Material: Carbide insert built for rigidity and precision in demanding environments.

Designed to optimize threading performance, this insert supports consistent thread quality on Whitworth and other common forms, making it ideal for machine shops and production environments. The TiAlN coating helps resist heat buildup and wear, reducing downtime and extending the life of each edge. The five-length selection lets you tailor depth of cut and reach to your machine and workpiece, improving efficiency and reducing setup time. With dual cutting edges, you get more usable life per insert, lowering replacement frequency in demanding jobs such as valve bodies, fittings, housings, and fasteners. Choose the right length and pitch to match your target thread standard and tooling setup for best results.
