Carmex Carbide Threading Insert - ACME - TiAlN Coated - 40I3ACME

The Carmex Carbide Threading Insert - ACME with TiAlN coating is a durable, versatile tool designed for machinists who need reliable threading performance across a range of common profiles. Built for precision turning, it combines multiple lengths with a robust coating to keep cycles productive.

• Length Variety: 5 length options from 12 mm to 40 mm to fit a wide range of threading applications and depths.
• Wide Pitch Range: Capable of handling pitches from 0.5 mm (32 TPI) up to 6.0 mm (4 TPI), depending on the chosen length.
• Double-Sided Cutting Edges: Each insert provides two cutting edges for extended life and consistent performance, with exceptions for BSPT/NPT/NPTF/American Buttress/API RD profiles.
• Internal & External Capability: For many thread profiles, the same insert can machine both internal and external threads, reducing tool swaps—note exceptions include ISO, UN, NPSM, UNJ, and Acme.
• TiAlN Carbide Coating: TiAlN coating enhances wear resistance and high-temperature stability, helping maintain accuracy and finish in challenging materials.
• ACME Threading Ready: Specifically suited for ACME threads, delivering dependable performance in this demanding profile while remaining versatile for other common thread types.

This insert is ideal for production environments where minimizing tool changes and maximizing insert life matters. Use it to streamline threading operations on steel, stainless, or other common workpieces, while maintaining tight tolerances and clean thread finishes. Its dual-edge design and coating work together to extend tool life under typical cutting conditions, enabling steadier feeds, better surface quality, and fewer interruptions in your machining workflow. For optimal results, pair the appropriate length with the target pitch, apply proper coolant, and select feeds and speeds tailored to your material and machine capabilities.
