Carmex Carbide Threading Insert for Whitworth and other common thread profiles offers a durable, versatile solution for professional machinists. TiAlN-coated carbide ensures reliable performance across a range of pitches and lengths, making it a practical choice for busy workshop environments.

• Five lengths: available from 12 mm to 40 mm, enabling threading setups that span pitches from 0.5 mm (32 TPI) to 6.0 mm (4 TPI).
• Double-sided design: two cutting edges extend tool life, with exceptions for BSPT/NPT/NPTF/American Buttress/API RD.
• Internal/external capability: in many thread forms, a single insert can machine both internal and external threads (except ISO/UN/NPSM/UNJ/Acme).
• Whitworth threading: optimized for Whitworth and other common thread profiles, delivering consistent results.
• TiAlN coating: enhanced hardness and heat resistance for longer insert life and improved surface finish.

This insert set minimizes tool changes and maximizes versatility on the shop floor. The double-edged design reduces downtime, while the broad length and pitch range covers a wide spectrum of threading tasks—from precise Whitworth bolts to standard, everyday thread forms. The TiAlN coating helps maintain cutting performance under heat, delivering reliable, repeatable results across multiple runs and setups.
