The Carmex Carbide Threading Insert – Unified, TiAlN coated in the 30E18UN designation is a versatile threading solution designed for machinists who need dependable performance across common thread profiles.

• Coating: TiAlN coating enhances wear resistance and heat tolerance for longer edge life during high-speed threading.
• Material: Carbide construction delivers rigidity and precision for consistent thread forms.
• Profiles covered: A comprehensive collection that spans all the standard thread profiles used in everyday milling and turning tasks.
• Lengths: Five length options ranging from 12 mm to 40 mm to fit a variety of toolholders and part geometries.
• Pitch range: Handles pitches from 0.5 mm (32 TPI) up to 6.0 mm (4 TPI) for broad application coverage.
• Edge design: Double-sided inserts with two cutting edges (except for BSPT, NPT, NPTF, American Buttress, and API RD) to maximize usable life.
• Internal/External versatility: For many thread profiles, the same insert can machine both internal and external threads (with exceptions such as ISO, UN, NPSM, UNJ, and Acme).

This unified insert family reduces tool changes and simplifies inventory while delivering reliable, repeatable thread quality. The TiAlN coating helps maintain sharpness in demanding materials and high-speed conditions, making it well-suited for production runs and precision machining alike. Ideal for job shops and workshops seeking a practical, long-lasting threading solution without compromising accuracy or efficiency.
