End Mill with Smaller Inserts Reliably Roughs, Finishes

Sandvik Coromant offers its CoroMill 390 end mill with size 07 inserts, making it ideal for shoulder milling, edging, linear and helical ramping, plunge milling, slot milling, and face milling. From roughing to finishing, it offers reliability, precision and productivity, the company says. Suitable for all machine types, this end mill can be used with different materials and applications in mixed production.

Grades for the CoroMill 390 are available for all materials, Sandvik says. The insert grade GC1130, produced with Zertivo technology, is designed to give the cutter extra security when milling steel. The smaller inserts deliver higher cutter-tooth density for productivity.

The torque key is designed for size 07 inserts and is said to provide consistent clamping. It has built-in spring functionality that enables the user to mount inserts with the correct clamping force for reliable and consistent tool life. Coolant-through technology provides additional heat and chip control.
