Description

The Carmex Vertical Milling CMT Three Flute Insert - Threading - C25I4.5ISOMT7 is a versatile vertical milling indexable insert designed to handle threading, grooves, chamfers and more with consistent precision. Ideal for a broad audience—engineers, buyers, tradespeople and hobbyists—this solution delivers reliable results in demanding milling and threading tasks. The three-flute design enhances stability and chip control during vertical mill-thread operations, helping you achieve smooth, repeatable cuts.

  • Ground profile inserts for high precision: Precisely ground profiles deliver excellent performance and tight tolerances, supporting high-quality thread and surface finish even on demanding parts.
  • Universal threading with repeatable clamping: One insert works for both right-hand and left-hand threads, paired with a solid, accurate clamping method that ensures full repeatability across setups.
  • Complete tooling options with coolant bore: Toolholders include weldon shank and coolant bore for quick setup and reliable cooling; chamfer inserts are also available to expand your finishing options.

Designed to improve productivity and consistency, this insert supports higher machining parameters without sacrificing surface quality. Its robust clamping and universal threading capability reduce setup time and part rework, making it a dependable choice for shops that require precise threads, grooves and chamfers in a single, adaptable solution.
