The Carmex Vertical Milling CMT Three Flute Insert for Full Radius Grooving (C18R08MT7) is a versatile, high‑precision indexable insert designed for vertical milling tasks. It’s ideal for engineers, machinists, and shops that need reliable grooves, threads, chamfers, and more from a single, adaptable cutting solution.

Ground profile geometry delivers consistent cutting performance and excellent surface quality even at higher machining parameters. The solid, accurate clamping method ensures full repeatability across multiple cycles, and the same insert can be used for both right‑hand and left‑hand threads, simplifying setup and inventory. When paired with compatible Weldon‑shank toolholders (with coolant bore), it integrates smoothly into existing setups for efficient production.

• Ground profile for high precision: Delivers tight tolerances and stable geometry for accurate grooves and threads, enabling reliable performance at higher feed and speed without sacrificing finish.
• One insert for RH/LH threads: Uses a single insert for both right‑ and left‑hand threading, reducing tool changes, stocking needs, and setup time.
• Three‑flute, full‑radius geometry: Provides balanced rigidity and smooth cutting for clean grooves and chamfers, enhancing tool life and finishing quality.

Designed to streamline your vertical milling workflow, this insert supports precise thread and groove production with repeatable results. Its universal threading capability, combined with compatible Weldon‑shank toolholders and coolant bore, helps reduce downtime, improve throughput, and deliver consistent results across demanding applications.
