The Carmex Carbide Threading Insert - Unified - TiAlN Coated (40E12UN) is a versatile, high-performance threading solution for professionals working with unified thread profiles. Built for durability and precision, it supports a broad range of machining needs in a single, reliable insert family.

• Coating: TiAlN coating provides enhanced wear resistance and heat tolerance for reliable threading at higher speeds.
• Profile coverage: Designed to cover all common thread profiles with a single, cohesive insert family—reducing tool inventory and setup time.
• Lengths: Five available lengths, from 12 mm to 40 mm, to fit a variety of workpiece sizes and applications.
• Pitch range: Capable of handling pitches from 0.5 mm (32 TPI) to 6.0 mm (4 TPI), depending on the chosen length.
• Double-edged design: Each insert is double-sided, offering two cutting edges for extended tool life (exceptions apply for BSPT/NPT/NPTF/American Buttress/API RD).
• Internal/External versatility: In many profiles, the same insert can machine both internal and external threads, reducing tool changes (with some standard-specific exceptions ISO/UN/NPSM/UNJ/Acme).
• Material and precision: Carbide construction delivers rigidity and consistent thread formation for clean, accurate results.

This threading insert family is ideal for shops and engineers who demand flexibility and repeatable performance across a range of unified thread standards. With multiple lengths, a robust TiAlN coating, and a two-edge design, it reduces downtime, simplifies tooling, and helps you achieve precise threads on both internal and external components.
