The Carmex Carbide Threading Insert - Unified - TiAlN Coated (12I20UN) is a versatile cutting solution designed for machinists who work with a wide range of standard thread profiles. Built for precision and durability, it delivers reliable threading performance across common tasks with a single, robust insert.

• Coating: TiAlN coating provides enhanced hardness and heat resistance for longer edge life in demanding cutting conditions.
• Material: Solid carbide insert delivers rigidity and stable performance under high temperatures and loads.
• Thread profiles: Unified threading coverage across most common profiles with one insert (note: ISO / UN / NPSM / UNJ / Acme have exceptions).
• Double-sided edges: Each insert has two cutting edges for extended use; simply flip to extend life (exceptions apply for BSPT / NPT / NPTF / American Buttress / API RD).
• Length range: Five lengths available, spanning from 12 mm to 40 mm to fit different threading tasks.
• Pitch range: Depending on length, supports pitches from 0.5 mm (32 TPI) up to 6.0 mm (4 TPI).

The 12I20UN insert enables consistent thread quality on both internal and external applications for many profiles, reducing the need for multiple tools and streamlining setup. Its carbide substrate and TiAlN coating minimize wear and heat buildup, helping you maintain precise thread dimensions and surface finish over multiple passes. Ideal for job shops and production environments that require reliable, ready-to-use threading inserts across a variety of standard profiles.
