The ones our customers buy most.Description
The Carmex Vertical Milling CMT Three Flute Insert – Corner Rounding (C18CR15MT7) is a precision, indexable cutting solution designed for vertical milling tasks that require accurate corner radii, grooves, threads, and chamfers. It’s tailored for engineers, machinists, and production operators who need reliable performance and consistent results across a variety of materials.
Ground-profile inserts deliver high precision and excellent surface quality even at higher machining parameters. The solid, accurate clamping method ensures full repeatability, and the same insert can be used for both right-hand and left-hand threads. Toolholders include a weldon shank and coolant bore for straightforward setup and efficient cooling. Chamfer inserts are also available to extend versatility.
- Ground-profile, three-flute design for precise corner rounding: Provides stable cutting action, efficient chip evacuation, and tight, repeatable radii for clean corners at higher speeds.
- Universal RH/LH threading with solid, repeatable clamping: One insert handles both thread directions, enabling faster setup, lower inventory, and consistent results over long runs.
- Ready-to-integrate tooling with weldon shank and coolant bore: Drops into standard toolholders, supports through-spindle coolant, and pairs with chamfer inserts for expanded capability, boosting durability and workflow efficiency.
This combination delivers a dependable, versatile milling solution that improves part precision, reduces rework, and speeds up setups in busy shops. With consistent corner radii, reliable clamping, and straightforward integration into existing toolholding and cooling systems, you can achieve repeatable quality and faster overall production.
