The Carmex Carbide Threading Insert – Unified, TiAlN coated – is a durable, versatile solution for machinists tackling a wide range of common thread profiles on lathes and milling machines. Designed to deliver reliable performance across multiple pitches, it combines carbide toughness with a protective TiAlN coating for extended cutting life.

• TiAlN-coated carbide construction: exceptional hardness and heat resistance for longer wear life and consistent cutting performance.
• Five length options (12–40 mm): flexible sizing to fit a variety of toolholders and reach requirements without changing inserts.
• Wide pitch coverage: supports pitches from 0.5 mm (32 TPI) to 6.0 mm (4 TPI), covering the most common thread standards.
• Double-sided cutting edges: two usable cutting edges per insert (except for BSPT / NPT / NPTF / American Buttress / API RD), effectively doubling life per insert.
• Internal & external threading capability: for many profiles, the same insert can machine both internal and external threads, boosting versatility (with exceptions for ISO / UN / NPSM / UNJ / Acme).

This Unified threading solution is ideal for job shops, maintenance teams, and production environments that require a single insert family to cover multiple thread standards. Expect clean, accurate threads, reduced tool changes, and lower tooling costs as you work across steel, stainless, aluminum, and other common metals.
