Part of our industry-leading range, this laydown triangular insert delivers reliable performance across both simple and the most demanding applications, helping you complete threads with consistent accuracy and finish.

  • Broad UN-thread compatibility: Covers UNC, UNF, UNEF and UNS, so you can complete most internal-threading jobs with a single insert family, reducing tool changes.
  • Stable laydown triangular geometry: The laydown triangular insert design provides robust support and smooth cutting action, delivering consistent thread profiles and a better surface finish.
  • Right-hand cutting for reliable internal threading: Specifically oriented for right-handed threads, optimizing engagement and extending insert life across a wide range of applications.

Using this insert simplifies your workflow: one insert family covers multiple thread standards, reducing tool-change time and inventory complexity. The robust geometry supports steady cutting, helping you achieve clean, accurate internal threads with every job.

Buying experience
Phone requests are handled quickly and without any fuss. The website is easy to use and straightforward to order from. It’s especially helpful that it shows real‑time availability, so we don’t need to call to confirm whether parts will arrive.
