The ones our customers buy most.Description
The Carmex Vertical Milling CMT Three Flute Insert - Corner Rounding (C25CRD20MT7) is a precision indexable insert designed for vertical milling and corner rounding. Its three‑flute geometry supports a wide range of operations—from threads and grooves to chamfers—using a single, repeatable insert. Chamfer inserts are also available, and the insert pairs with Weldon‑shank toolholders that include a coolant bore for efficient cooling and chip control.
- Ground-profile inserts for precision and surface quality: Ground profiles deliver high precision and excellent performance, enabling tight tolerances and a smooth surface finish even at higher machining parameters.
- One insert for both right- and left-hand threads: The same insert can handle both threading directions, reducing inventory and downtime while ensuring reliable threading results.
- Solid clamping with coolant‑ready toolholders: A robust, accurate clamping method provides full repeatability across setups; toolholders with Weldon shank and a coolant bore support efficient cooling and longer tool life.
Designed to streamline workflows in demanding environments, this insert minimizes tool changes and setup time while delivering consistent, high-quality corner rounding, threads, grooves, and chamfers. The combination of ground-profile precision, universal threading capability, and integrated toolholding options helps you complete parts faster with repeatable results and reduced maintenance.
