Answer

As you can see from this video, the benefits of using a button style insert can be large. The flexibility of 8 locations in this example means better value for money as well as the other points in this blurb from Coromant themselves:

“The light cutting action of the CoroMill 300 cutter is extended with larger inserts with a new, secure insert locking interface. The CoroMill 300 round insert milling cutter combines low cutting forces
with high productivity. Its positive cutting angles take light cuts and make it possible to get high feed rates even in weaker machines and in unstable conditions. This addition to CoroMill 300 includes inserts in size iC 20 mm and 1.00 inch, and cutters in diameters 3.00-8.00 inch and 66-200 mm.”
