Introducing Carmex Carbide Threading Insert - Unified - TiAlN Coated - 14I12UN: a versatile threading solution built for professional workshops that demand broad profile coverage with a single tool. This TiAlN-coated carbide insert delivers reliable performance across common thread forms, helping you tackle diverse projects with confidence.
- Thread profiles covered: A comprehensive collection that spans all common thread forms, available in five lengths from 12 mm to 40 mm. Depending on length, it handles pitches from 0.5 mm / 32 TPI to 6.0 mm / 4 TPI.
- Double‑sided cutting edges: Most inserts provide two cutting edges for extended tool life; note exceptions for BSPT / NPT / NPTF / American Buttress / API RD profiles, which use a single edge.
- Internal & external threading versatility: For many thread profiles, the same insert can machine both internal and external threads, reducing setup time and tool changes. Exceptions apply to ISO / UN / NPSM / UNJ / Acme profiles.
- TiAlN coating: The TiAlN coating enhances wear resistance and enables better performance at higher cutting speeds, helping extend insert life in demanding materials.
- Unified thread compatibility: Specifically optimized for Unified thread forms, delivering consistent results across common sizes and applications.
- Carbide construction: Durable carbide substrate provides rigidity and precision for clean thread profiles and repeatable tolerances.
This insert is designed to maximize productivity by minimizing tool changes and accommodating a wide range of thread forms. It’s ideal for machinists and shops that work on varied components, from precision fasteners to complex parts, where reliable threading performance and long edge life matter. The combination of a TiAlN-coated carbide body, multiple length options, and versatile cutting edges helps you achieve consistent thread quality and efficiency across your daily operations.
