Description

The Carmex Vertical Milling CMT Three Flute Insert - Full Radius Grooving (C12R11MT7) is an indexable insert designed for vertical milling applications. It enables precise grooves, threads, chamfers, and more when paired with Carmex vertical mill-thread holders. Built for dependable performance across a range of common manufacturing tasks, it helps shops achieve repeatable results with confidence.

Ground profile inserts deliver exceptional precision and surface quality, even at higher cutting parameters. The solid, accurate clamping system ensures repeatable alignment with every change, while the same insert can be used for both right-hand and left-hand threads, simplifying setup and inventory. Toolholders sold with the system include a Weldon shank and coolant bore for reliable cooling and stability.

  • Precision-ground profile: Delivers tight tolerances and consistent finishes for accurate grooves and threads at higher productivity levels.
  • Three-flute, full-radius geometry: Provides efficient material removal and smooth, clean grooves with reduced edge wear and better chip control.
  • Universal threading and robust clamping: Works for both right- and left-hand threads with a solid clamping method, and compatible toolholders with a coolant bore for reliable, repeatable results.

Using the Carmex C12R11MT7 insert helps you streamline setups, minimize downtime, and achieve dependable results across multiple milling tasks—grooving, threading, and chamfering—without swapping between different inserts. The combination of precise ground profiles, durable clamping, and versatile threading support translates into faster cycles, fewer rework steps, and improved overall performance on the shop floor.
