CoroMill 390

The CoroMill^® 390 family covers a large, versatile programme for many applications. It generates a good quality 90-degree shoulder and is ideal for ramping and helical interpolation. CoroMill^® 390 is available with integrated dampening for a productive and vibration-free machining.

Benefits

Large depth of cut and steep ramping capability

Large, versatile program
Close tolerances giving excellent surface finish and minimal mismatch

Features

Light-cutting insert geometry for low cutting forces and to avoid deflection and vibration
Cutter versions for shoulder milling and long edge milling
Through coolant
Insert sizes -11, -17 and -18 for depths of cut up to 15.7 mm
(0.618 inch)
Large range of insert corner radii, geometries and insert grades
Coromant Capto coupling, Cylindrical shank, Arbor, CIS Arbor, Weldon, and Threaded mounting
Oversized diameter for clearance is available

Application

Oversized cutters enhance the accessibility and provide natural clearance to tight fixtures
Cutters with integrated Coromant Capto coupling and adaptors provide the optimal rigidity for use on extended tool assemblies
Silent Tools vibration dampening for increased metal removal and improved surface finish, when using slender tools
Turn milling, roughing and finishing, using one or more dedicated wiper inserts available in size 11 and 18 and radius 0.8 and 1.6
