Description

The Carmex Vertical Milling CMT Three Flute Insert – Threading is a versatile vertical milling indexable insert system designed to tackle threads, grooves, chamfers, and more from a single, flexible setup. It’s ideal for engineers, technicians, and shop floor operators who require reliable, repeatable results across a range of materials and applications.

Ground-profile inserts deliver high precision and excellent performance, even at higher machining parameters, with a focus on high surface quality. The solid, accurate clamping method enables full repeatability, and the same insert can be used for both right-hand and left-hand threads. Toolholders include a Weldon shank and coolant bore, with chamfer inserts also available for expanded capability.

  • Ground profile inserts for high precision: Delivers consistent geometry and high surface quality, enabling accurate threading and smooth finishes under demanding conditions.
  • One insert for both right- and left-hand threads: Simplifies inventory and speeds setup by eliminating the need for separate threading inserts.
  • Complete tooling with Weldon shank, coolant bore, and chamfer options: Streamlines integration into existing machines and expands capabilities with chamfer inserts available.

With the Carmex Vertical Milling CMT Three Flute Insert, you gain a reliable, repeatable threading solution that fits into standard vertical milling workflows. Its precision-ground inserts, robust clamping, and flexible tooling options help reduce downtime, improve part quality, and simplify setup—so you can move from job to job with confidence.
