Suitable for all machine types, the CoroMill 390 with size 07 inserts also is said to be suitable for mixed production and can be used with different materials and applications.

Grades for the CoroMill 390 with size 07 inserts are available for all of materials. The new insert grade GC1130, produced with Zertivo technology, reportedly gives this cutter an extra dimension of security when milling steel. The smaller inserts deliver higher cutter-teeth density for superior productivity, according to Sandvik.
