CoroMill® 300 – Light-cutting face and profile milling cutters
Helical ramping of larger diameter holes with CoroMill® 300 provides the most secure and productive method. The cutting forces are much lower than in drilling, which is challenging when dealing with the interrupted exit into the bore.
For rough milling around a boss, use CoroMill® 300 with a roll-in program combined with round inserts to reduce notch wear and allow for high feed rates.
