Carmex Carbide Threading Insert - Unified - TiAlN Coated - 40I12UN

Carmex Carbide Threading Insert, Unified, TiAlN Coated, model 40I12UN, is a versatile solution designed for machinists who need reliable threading performance across a wide range of profiles. Built for accuracy and durability, this insert family delivers consistent results in both internal and external threading tasks where supported.

• Model: 40I12UN – Unified, TiAlN coated carbide threading insert for broad compatibility and robust wear resistance.
• Universal thread coverage: A versatile collection that spans all common thread profiles with a single, ready-to-use tool solution.
• Five length options: Available in five lengths ranging from 12 mm to 40 mm to fit a variety of workpiece depths and tooling setups.
• Pitch range: Handles pitches from 0.5 mm (32 TPI) to 6.0 mm (4 TPI), accommodating fine to coarser threading requirements.
• Double-sided cutting edges: Each insert features two cutting edges (except for BSPT/NPT/NPTF/American Buttress/API RD profiles), maximizing usable life per insert.
• Internal & external threading capability: For many thread profiles, the same insert can machine both internal and external threads, reducing tool changes (note: exceptions apply for ISO/UN/NPSM/UNJ/Acme).
• Carbide construction: Precision-ground carbide substrate delivers rigidity and repeatable thread form for high-accuracy results.
• TiAlN coating: TiAlN coating enhances wear resistance and longevity in demanding materials and threading operations.

Designed for professional shops and precision-focused operators, this Carmex Unified threading insert helps you complete more jobs with fewer tool changes. The combination of multiple lengths, broad pitch compatibility, and dual cutting edges translates to smoother finishes, tighter tolerances, and improved productivity on a variety of materials. Whether you’re tackling standard profiles or transitioning between internal and external threads where supported, this TiAlN-coated carbide insert is built to perform with consistency and reliability.
