The Carmex Carbide Threading Insert in Whitworth form offers a reliable, all-in-one threading solution for machinists who produce Whitworth and other common thread profiles. Coated with TiAlN for wear resistance, this insert is built for precision and longevity across multiple pitches and thread types.

• Thread profiles: A versatile collection of threading inserts covering all common thread profiles.
• Length options: Five lengths from 12 mm to 40 mm to suit different toolholders and depth requirements.
• Pitch range: Handles pitches from 0.5 mm (32 TPI) up to 6.0 mm (4 TPI).
• Double-sided cutting edges: Each insert provides two cutting edges for extended life (except for BSPT/NPT/NPTF/American Buttress/API RD).
• Internal/External capability: For many thread profiles, the same insert can machine both internal and external threads (excluding ISO/UN/NPSM/UNJ/Acme).
• Coating and material: TiAlN-coated carbide for improved wear resistance and heat tolerance.
• Size/Grade: Whitworth 14-24W specification for compatibility with standard Whitworth tooling setups.

With these features, you gain consistent thread quality, reduced tool changes, and longer tool life in demanding turning and milling operations. The double-cut edges maximize material removal per edge, while the TiAlN coating lowers built-up edge and wear, helping you maintain tight tolerances on both internal and external threads. This insert is a practical choice for shop floors that balance legacy Whitworth work with modern threading needs, offering versatility without sacrificing precision.
