Carmex Carbide Threading Insert - Unified - TiAlN Coated - 21I10UN

The Carmex Carbide Threading Insert - Unified - TiAlN Coated - 21I10UN is a single, versatile threading solution for machinists who need to cover a wide range of profiles with fewer tool changes. The TiAlN-coated carbide insert delivers clean starts and reliable wear resistance, making it suitable for job shops and production environments alike.

• Unified threading coverage: A versatile insert system that spans all common thread profiles, reducing inventory and setup time.
• Five available lengths: Five lengths range from 12 mm to 40 mm to fit diverse holders and applications.
• Double-sided cutting edges: Each insert has two cutting edges for extended life (except for BSPT/NPT/NPTF/American Buttress/API RD).
• Internal and external threading capability: For many profiles, the same insert can machine both internal and external threads (excluding ISO/UN/NPSM/UNJ/Acme).
• TiAlN coating: TiAlN coating provides improved wear resistance and heat tolerance, helping to extend tool life in demanding materials.
• Carbide construction: Rigid carbide body delivers precise, repeatable threading performance.
• Pitch range: Supports pitches from 0.5 mm (32 TPI) up to 6.0 mm (4 TPI), depending on length.

The 21I10UN insert is designed for reliability in CNC turning and manual operations, delivering consistent thread geometry with fewer inserts needed for a wide variety of profiles. Its unified approach, dual-cutting edges, and hard-wearing TiAlN coating translate into real-world benefits: faster setups, lower tooling costs, and dependable performance on a broad range of materials and thread standards.
