Carmex Carbide Threading Insert – Unified, TiAlN Coated (30E20UN) is a versatile threading solution crafted for precision machinists who need a single insert family that covers a broad range of thread profiles. This TiAlN-coated carbide insert delivers reliable performance across common threading tasks in a compact, ready-to-use package.

• Coating: TiAlN-coated carbide for enhanced hardness, wear resistance, and heat tolerance during demanding threading operations.
• Thread Profiles: Unified design that covers all common thread profiles with a single insert family, reducing tool changes and inventory complexity.
• Length Options: Five length choices available, ranging from 12 mm to 40 mm, to fit diverse machine setups and reach requirements.
• Pitch Range: Depending on length, capable of handling pitches from 0.5 mm / 32 TPI up to 6.0 mm / 4 TPI for both metric and imperial threads.
• Double-Sided Edges: Inserts are double-sided with two cutting edges for most profiles, extending usable life; note exceptions apply for BSPT, NPT, NPTF, American Buttress, and API RD.
• Internal/External Use: For many thread profiles, the same insert can machine both internal and external threads (exceptions: ISO / UN / NPSM / UNJ / Acme).

This threading insert is engineered to streamline production by offering broad compatibility, durable performance, and flexible mounting options. Its Unified approach means fewer tool changes and simpler planning, while the TiAlN coating helps sustain cutting performance across varied materials and applications.
