Carmex Carbide Threading Insert - Whitworth - TiAlN Coated - 21-16W

Carmex Carbide Threading Insert in Whitworth form offers a durable, versatile solution for precision thread cutting across the most common profiles. Designed for machinists and workshops that need reliable performance, this TiAlN-coated insert delivers consistent results and extended edge life.

• Thread profiles covered: A versatile collection that spans all common thread profiles, simplifying tooling in mixed jobs.
• Five lengths: Available in five lengths ranging from 12 mm to 40 mm to fit a variety of holders and applications.
• Pitch range: Depending on length, capable of handling pitches from 0.5 mm / 32 TPI up to 6.0 mm / 4 TPI.
• Double-sided cutting edges: Two cutting edges per insert (except for BSPT / NPT / NPTF / American Buttress / API RD), effectively doubling usable life between regrinds or replacements.
• Internal/External threading compatibility: For many thread profiles, the same insert can machine both internal and external threads (with exceptions ISO / UN / NPSM / UNJ / Acme).
