The Carmex Carbide Threading Insert for ACME (TiAlN-coated, model 30I6ACME) is a versatile, high-precision tool designed for professionals who machine ACME-style threads. Built to handle a wide range of profiles with a single insert family, it delivers dependable performance across common threading tasks in production and job-shop environments.

• Coating & material: TiAlN-coated carbide for enhanced heat resistance, wear protection, and extended insert life in demanding threading operations.
• Double-edged design: Each insert provides two cutting edges, maximizing usage per insert (note: BSPT/NPT/NPTF/American Buttress/API RD profiles may differ).
• Length options: Five lengths available from 12 mm to 40 mm to suit various toolposts, holders, and depths of cut.
• Pitch range: Suitable for pitches from 0.5 mm (32 TPI) up to 6.0 mm (4 TPI), with performance depending on the chosen length.
• Internal/external threading versatility: For many thread profiles, the same insert can machine both internal and external threads, reducing tool changes (with profile-specific exceptions).

This insert family focuses on practicality and consistency. The TiAlN coating helps maintain edge integrity under heat and heavy cuts, while the dual cutting edges offer better tool life and lower downtime. With five length options and a broad pitch range, it’s well-suited for automotive, machine-building, and precision manufacturing applications where ACME threads are common. The design supports reliable internal and external threading across a wide array of profiles, enabling you to complete more work with fewer tool changes and a steadier, more predictable finish.
