Description
Carmex Vertical Milling CMT Three Flute Insert - 90° Chamfering - C12C90MT7 is a precision indexable insert crafted for vertical milling tasks that demand clean, accurate chamfers, threads, and grooves. Its three-flute geometry and ground profile deliver smooth cutting action and consistent results, even at higher speeds and feeds.
- Precision-ground CMT profile: Delivers tight tolerances and consistently clean 90° chamfers with excellent surface finish, boosting productivity at elevated cutting parameters.
- Rigid, repeatable clamping: Solid, accurate clamping minimizes runout and vibration, ensuring repeatable results part after part and reducing rework.
- Bidirectional threading compatibility & coolant-ready shank: One insert handles both right- and left-hand threads, and is designed to pair with Weldon-shank toolholders with a coolant bore for easy setup and effective heat management.
Designed to fit into demanding production environments, this insert simplifies setups, extends tool life, and delivers reliable performance across a range of materials. Its combination of precision geometry, robust clamping, and versatile threading capability helps you maintain consistent quality while maximizing uptime and throughput.
