The Carmex Vertical Milling CMT Three Flute Insert - Full Radius Grooving - C18R11MT7 is a precision vertical milling insert designed to handle full-radius grooving, threads, chamfers, and more in a single, compact tool. Built for a wide audience—engineers, buyers, tradespeople, hobbyists—this insert system delivers reliable performance across a range of materials and applications.

With a ground profile for high precision, it maintains excellent results even at demanding cutting parameters, producing clean profiles and high-quality surface finishes. A solid, accurate clamping method ensures full repeatability from one cycle to the next. The same insert can be used for both right-hand and left-hand threads, simplifying inventory and setup. Toolholders include a Weldon shank and a coolant bore, enabling straightforward integration into existing machines; chamfer inserts are also available to extend capabilities.

• Ground-profile precision for accuracy and surface quality: The ground profile maintains tight tolerances and delivers a smooth finish even at higher speeds and feeds, ideal for demanding grooves and threads.
• Rigid, repeatable clamping: Solid clamping minimizes runout, reduces setup time, and ensures consistent results across multiple passes.
• Versatile RH/LH compatibility with coolant bore and Weldon shank: The same insert works for right- or left-hand threads, and the toolholders provide a coolant bore and Weldon shank for easy integration; chamfer inserts expand capability without swapping tools.

In use, you’ll experience a streamlined milling workflow: quick tool changes, reliable repeatability, and high-quality feature finishes—from grooves to threads to chamfers. The ground-profile geometry plus robust clamping keeps tolerances tight across shifts, while the RH/LH compatibility and integrated coolant bore simplify setup and chip control. This makes the Carmex CMT Three Flute Insert a practical, long-term solution for automotive, hydraulic, and general precision machining where consistent results and fast turnaround matter.
