Part of Carmex's trusted family of laydown triangular inserts, it's built to handle a wide range of thread standards, including the NPTF right-hand threads common in piping and hydraulic components. Ideal for engineers, machinists, and maintenance technicians, it delivers consistent results with minimal setup.

  • Broad thread compatibility: Covers a broad range of thread standards, including NPTF right-hand threads, helping you complete more jobs with a single insert family and reducing tool changes.
  • Laydown triangular geometry for stable cutting: Three cutting edges and a compact geometry provide stable engagement, reduce chatter, and deliver clean, consistent internal threads across materials.
  • Built for reliability across basic to demanding applications: Crafted to perform under varying conditions, delivering dependable results and longer tool life with less downtime.

When you choose this Carmex internal insert, you’re equipping your operation with a versatile, repeatable threading solution.
