The Carmex Carbide Threading Insert — Unified — TiAlN Coated — 14I20UN is a versatile carbide solution designed to cover a wide range of unified thread profiles with a single, durable tool interface.

• Coating: TiAlN-coated for enhanced wear resistance and heat tolerance at higher cutting speeds.
• Thread Profiles Coverage: A comprehensive collection that spans all common thread profiles.
• Length Options: Five lengths available from 12 mm to 40 mm to fit different workpiece sizes and reach requirements.
• Pitch Range: Capable of handling pitches from 0.5 mm (32 TPI) to 6.0 mm (4 TPI).
• Double-Sided Edges: Two cutting edges on most inserts, extending tool life (except for BSPT / NPT / NPTF / American Buttress / API RD).
• Internal/External Capability: For many thread profiles, the same insert can machine both internal and external applications (excluding ISO / UN / NPSM / UNJ / Acme).

This threading insert is designed to streamline threading operations by offering durable performance across a broad set of profiles. The unified geometry reduces tool changes and inventory needs, while the TiAlN coating helps maintain edge life and finish quality under demanding conditions. With multiple lengths and a wide pitch range, it’s a practical choice for general machining, automotive, and precision manufacturing applications that require reliable, consistent threads.
