CoroMill® 415

Small-diameter high feed face milling cutter

Application tips

Chip formation

Successful chip formation and chip evacuation is the key to high-quality milling operations. Learn more about how to form the perfect chips, and don’t forget the golden rule: Thick to thin.

Three keys to successful ramping

Ramping is an efficient way to approach the workpiece when machining pockets. There are three key considerations that need to be correctly applied for successful ramping operations.

Cutter position

Each time a milling edge enters a cut, it is subjected to a shock load. The right type of contact between edge and material at the entry and also at the exit of a cut must be considered for successful milling.
