CoroMill® MR80
Cost-efficient face and profile milling
Reliable roughing
Designed for challenging roughing operations in a wide range of face and profile milling operations in steel and stainless steel, CoroMill® MR80 offers reliable and cost-efficient machining thanks to the security of a round insert cutting edge and our patented shim design.
An economical solution
Thanks to the double-sided insert design and a total of 12 indexing possibilities, CoroMill® MR80 is an economical solution in primarily face milling operations, as well as in limited shoulder and pocket milling applications.
Problem-solver
Thanks to its light cutting geometry, less load is exerted on the spindle, allowing CoroMill® MR80 to work as a problem solver in long overhang applications.
