Sandvik Coromant CoroMill 390
CoroMill 390 is a broad Sandvik Coromant indexable milling system for square-shoulder, profile, ramping, and related operations. Cutter size, connection, insert size, geometry, grade, corner radius, pitch, and ordering code define the usable system.
Product system overview
CoroMill 390 is a broad Sandvik Coromant indexable milling system for square-shoulder, profile, ramping, and related operations. Cutter size, connection, insert size, geometry, grade, corner radius, pitch, and ordering code define the usable system.
Industries and applications
- Square-shoulder and edging operations using the correct cutter and insert size.
- Profile, ramping, helical interpolation, and light-cutting applications where the selected geometry supports the operation.
- Long-reach or vibration-sensitive milling using an appropriate body, pitch, insert geometry, grade, and holder connection.
Technical and quote details
- Official records distinguish cutter bodies such as size 07 and insert platforms such as 1704.
- Insert codes retain geometry and grade, including ML, PM, and other application-specific chipbreakers.
- Cutter ordering codes identify diameter, connection, insert size, pitch, and hand.
- The official milling catalog supplies ordering-code tables and first-choice indicators across bodies and inserts.
- Item records provide CAD, drawings, GTC packages, tool data, and assembly functions.
Selection notes
Capture body and insert ordering codes separately, including size, geometry, grade, corner radius, pitch, connection, and hand.
Use the current Sandvik milling catalog and item-level assembly data for compatibility and replacement work.
Variables to validate
- CoroMill 390 spans multiple cutter and insert sizes that are not cross-compatible.
- Insert geometry, grade, corner radius, pitch, runout, projection, and operation determine performance.
- Catalog and campaign literature may cover different revisions; current item pages should control final ordering.
