The Carmex Carbide Threading Insert - Unified - TiAlN Coated - 40I6UN is a versatile, unified threading solution designed for machinists who need reliable performance across the most common thread profiles. With a durable TiAlN coating, this carbide insert is built to deliver consistent cutting edge performance in a variety of threading tasks.

• Five length options: Available in five lengths from 12 mm to 40 mm to suit different tooling setups and workpiece sizes.
• Wide pitch range: Depending on length, capable of handling pitches from 0.5 mm / 32 TPI up to 6.0 mm / 4 TPI.
• Double-sided design: Each insert has two cutting edges for many thread profiles, increasing usable life (exceptions: BSPT / NPT / NPTF / American Buttress / API RD).
• Internal & external compatibility: In many profiles, the same insert can machine both internal and external threads (exceptions: ISO / UN / NPSM / UNJ / Acme).
• TiAlN-coated carbide: High hardness and wear resistance for longer tool life and steadier performance on challenging materials.

This single, adaptable threading insert collection supports a wide range of operations, reducing tool swaps and inventory while delivering accurate thread profiles. It’s ideal for shops that routinely work with unified threading standards and need a dependable insert that can tackle both internal and external threads across multiple pitches.
