Carmex Carbide Threading Insert - UNJ - TiAlN Coated - 14E12UNJ

Carmex Carbide Threading Insert - UNJ is a TiAlN-coated carbide insert designed for precise threading across common profiles, ideal for professional shops handling UNJ and other standard thread forms with reliability and durability.

• Five lengths: Five length options (12 mm to 40 mm) to suit different toolholders and pitch requirements.
• TiAlN coating: Titanium Aluminum Nitride coating enhances wear resistance and hot-hardness, extending insert life in demanding materials.
• Double-edged cutting: Each insert is double-sided with two cutting edges for extended use—note: BSPT, NPT, NPTF, American Buttress, and API RD variants are not double-sided.
• Internal/External threading compatibility: For many profiles, the same insert can machine both internal and external threads, enabling faster setups; ISO, UN, NPSM, UNJ, and Acme profiles require dedicated inserts.
• Wide pitch coverage: Supports pitches from 0.5 mm (32 TPI) up to 6.0 mm (4 TPI), covering a broad range of metric and imperial threads.

This carbide threading insert family delivers consistent thread form and surface quality while reducing tool changes and downtime. The TiAlN coating boosts durability under high-temperature cutting, and the varied lengths provide practical versatility for different machining scenarios—from prototype runs to production work—without compromising precision on UNJ and other common thread profiles.
