Description

The Carmex Vertical Milling CMT Three-Flute Insert - 90° Chamfering (C25C90MT7) is a precision indexable insert designed for vertical milling tasks, including threads, grooves, and chamfers. It’s built for shops and workcells that require reliable, repeatable performance across a range of materials and applications.

Rooted in the CMT approach, this insert features a ground profile that delivers high precision and excellent surface quality. It is engineered to perform at higher cutting parameters while maintaining clean, consistent finishes, making it well-suited for demanding milling and chamfering work. The combination of a solid, accurate clamping method and universal threading capability ensures repeatable results whether you’re cutting right-hand or left-hand threads. Toolholders with Weldon shank and coolant bore add practicality for everyday production and setup flexibility. Chamfer inserts are also available to expand your milling capabilities without changing setups.

  • Ground profile for precision and surface finish: Tight tolerances and a refined geometry deliver high-precision features and superior surface quality, even at higher speeds and feeds.
  • Universal threading with rigid clamping: The same insert handles right- or left-hand threads, backed by a solid clamping system that ensures repeatable results across multiple parts.
  • Versatile toolholding with coolant bore and chamfer options: Weldon shank toolholders and coolant bore support efficient cooling and reliable performance, and chamfer inserts are available to broaden your milling applications.

This insert helps you optimize machining workflows by delivering consistent, high-quality chamfers and threaded features, reducing setup time, and improving throughput across a wide range of materials and applications.
