Carmex Carbide Threading Insert - Unified - TiAlN Coated, model 40E6UN, is engineered for versatile threading across the most common profiles on CNC lathes and manual machines. This TiAlN-coated carbide insert delivers reliable performance in a compact, cost-effective package, built to handle a variety of threading challenges in one toolholder.
- Thread profile coverage: A versatile collection that spans all common thread profiles to reduce tool inventories and setup changes.
- Length options: Available in 5 lengths, from 12 mm up to 40 mm, to fit different toolholders and applications.
- Pitch range: Designed to accommodate pitches from 0.5 mm / 32 TPI to 6.0 mm / 4 TPI for broad threading flexibility.
- Double-sided cutting edges: Each insert features two cutting edges (except for BSPT/NPT/NPTF/American Buttress/API RD), increasing tool life and reducing changeovers.
- Internal & External capability: For many thread profiles, the same insert can machine both internal and external threads, streamlining operations (with exceptions for ISO/UN/NPSM/UNJ/Acme).
- Coating & material: TiAlN coating on carbide delivers enhanced wear resistance and heat tolerance for extended insert life in demanding materials.
This unified approach means shops can tackle a wide range of threading tasks with a single, reliable insert. The combination of carbide rigidity, TiAlN protection, and dual cutting edges translates to steadier feeds, cleaner thread finishes, and fewer tool changes—whether you're threading through holes or external shafts. Ideal for machine shops dealing with varying thread standards, it helps maintain productivity without sacrificing precision.
