CoroMill® MS40
The ultimate tangential milling solution


Robust design with trusted power
CoroMill® MS40 is engineered with tangentially mounted inserts, maximizing the core strength of the tool body. Its design ensures effortless machining of the most demanding face and shoulder milling applications.

Side milling perfected
Designed as a true 90-degree cutter, CoroMill® MS40 offers accurate and reliable side milling and repeated passes. The outcome is flawless walls with precise dimensions, minimal roughness and perfect perpendicularity.

Four-edged stability
Optimized geometries ensure high performance and long insert tool life. The inserts are easy to index thanks to the side-access screw and offer flank edge relief independence from the main support face.

Application
- Optimized for true 90-degree shoulder milling and repeated passes in side milling
- The secondary application areas are face milling, full slot milling and plunge milling
- For roughing and finishing operations
ISO application areas
Steel
Stainless steel
Cast iron
Heat resistant super alloys
