Sandvik Coromant has launched the CoroMill MR20, an advanced indexable milling concept engineered to deliver unmatched stability, predictable performance and exceptional metal removal rates across demanding materials and applications.
Designed for manufacturers who require absolute process security, CoroMill MR20 brings new levels of confidence and productivity to profiling and face milling operations. It is a single-sided round-insert concept optimised for ISO M, ISO S and ISO P materials. Its combination of security and versatility makes it ideal for pocketing and complex profiling in titanium and other HRSA materials used in aerospace, as well as in oil and gas components.
The tool also excels in ISO P die and mould applications, delivering reliable roughing and semi-finishing performance. In ISO M materials, it handles heavy metal removal for pump and valve components with the high predictability and productivity these industries demand. CoroMill MR20 is Sandvik Coromant’s first-choice solution for these applications.
Predictable, repeatable performanceAlvaro Ruiz, global product application specialist at Sandvik Coromant, said: “Our goal while developing CoroMill MR20 was to create a polyvalent cutter that offers the highest level of process security. Customers machining high-value components need predictable, repeatable performance — and CoroMill MR20 delivers exactly that.”
CoroMill MR20 is engineered not only for performance but also for more sustainable machining. By enabling higher feed per tooth, the tool reduces the energy required during machining. Its long tool life means fewer inserts are consumed, lowering the overall carbon footprint associated with production. Mr Ruiz explained: “Increasing feed capability while extending tool life means fewer resources used and less waste generated. It is a win for productivity and for sustainability.”
An advanced tool design ensures superior resistance to fatigue and deformation ensuring repeatability and long cutter body life. The new integrated under-coolant system guarantees high performance, especially in long-chipping and difficult-to-machine material. One of the key innovations is the optimised insert seat design, where the large contact area between the insert and cutter body minimises micro-movement for maximum stability.
The six-edged insert features a thick, robust body for exceptional bulk strength and superior edge-line security. Tight manufacturing tolerances promote gradual and predictable insert wear, supporting efficient, unmanned production, minimised scrap and maximised operational uptime. With its combination of stability, versatility and cutting efficiency, CoroMill MR20 equips manufacturers to push performance boundaries while maintaining full control of their process.
