Kennametal HARVI I TE vs Sandvik Coromant CoroMill 390

Kennametal HARVI I TE and Sandvik Coromant CoroMill 390 are documented milling systems with different product architecture and application priorities. HARVI I TE is Kennametal's four-flute solid-carbide end-mill family for roughing and finishing across broad material and operation coverage. CoroMill 390 is a broad Sandvik Coromant indexable milling system for square-shoulder, profile, ramping, and related operations.

Side-by-side comparison

Category	Kennametal HARVI I TE	Sandvik Coromant CoroMill 390
System architecture	The core family uses four flutes with asymmetric divided flutes, variable helix, twisted end-face geometry, relief features, and chip gashes described on official item pages.	Official records distinguish cutter bodies such as size 07 and insert platforms such as 1704.
Documented application focus	Roughing and finishing with one four-flute solid-carbide family across steels, stainless steels, cast irons, high-temperature alloys, and selected hardened materials.	Square-shoulder and edging operations using the correct cutter and insert size.
Technical selection detail	End forms include square, radiused, chamfered, and ball nose with regular, short, long, and necked variants.	Insert codes retain geometry and grade, including ML, PM, and other application-specific chipbreakers.
Primary documented constraint	The HARVI name spans several distinct families; flute count, end form, grade, diameter, reach, and shank must be exact before comparing performance.	CoroMill 390 spans multiple cutter and insert sizes that are not cross-compatible.
Manufacturer-guided selection	Store the Kennametal material number and catalog ID with diameter, flute length, reach, end form, corner treatment, shank, grade, and holder projection.	Capture body and insert ordering codes separately, including size, geometry, grade, corner radius, pitch, connection, and hand.

Best fit by application

Selection notes

Use HARVI I TE when its documented application focus and technical configuration match the operation more closely; use CoroMill 390 when its documented architecture and constraints provide the better fit.

Compare complete configured assemblies and current manufacturer data rather than treating either family name as one universal item.

Variables to validate

HARVI I TE: The HARVI name spans several distinct families; flute count, end form, grade, diameter, reach, and shank must be exact before comparing performance.
CoroMill 390: CoroMill 390 spans multiple cutter and insert sizes that are not cross-compatible.
Normalize diameter or cutter size, reach, interface, work material, machine conditions, coolant, and acceptance criteria before comparing performance or cost.
