The Carmex Carbide Threading Insert in UNJ with TiAlN coating is a versatile, high-precision tool designed for machinists working on common thread profiles. Built for reliability in both CNC and manual turning, it’s designed to deliver consistent thread quality across a range of applications.

• Part Number: 14I24UNJ
• Coating: TiAlN-coated carbide for enhanced wear resistance and heat handling
• Length Options: Five lengths spanning from 12 mm to 40 mm
• Thread Range: Pitches from 0.5 mm / 32 TPI up to 6.0 mm / 4 TPI (depending on length)
• Cutting Edges: Double-sided with two cutting edges (except for BSPT / NPT / NPTF / American Buttress / API RD)
• Internal/External Capability: For many profiles, one insert can machine both internal and external threads (exceptions: ISO / UN / NPSM / UNJ / Acme)

Designed to simplify tooling, this insert combines robust carbide performance with a wear-resistant TiAlN coating to extend edge life in demanding materials and higher-speed operations. The double-edged design means you can flip for a fresh edge, reducing downtime between tool changes, while the five length options let you match depth of cut and thread diameter to your specific job. Ideal for precision threading tasks on lathes and CNC machines, it helps achieve clean, accurate threads with fewer passes.
