Sandvik Coromant 6416914 Square-shoulder Face Mill

Product Description

The SANDVIK COROMANT 6416914 is an indexable square-shoulder face mill designed for precision milling operations in metalworking and machining environments. Part of the CoroMill 390 series, this right-hand cutting tool accepts four R390-11.. style inserts held by screw clamping, delivering a 90-degree lead angle and a maximum depth of cut of 0.394 inches. The cutter body is constructed from steel and features through-coolant capability to manage heat at the cutting zone. It is installed and operated by machinists and tooling specialists on CNC machining centers and manual milling machines where square-shoulder profiles and face milling are required.

This face mill is suited for applications requiring precise 90-degree shoulder milling on ferrous and non-ferrous workpieces. With a 1-inch maximum cutting diameter and an overall height of 1.378 inches, it fits compact spindle setups and close-tolerance fixturing. The 0.9646-inch arbor hole diameter is matched to standard arbor configurations found in production and job-shop machining environments. It is commonly used in aerospace, general metalworking, and die-mold applications where wall straightness and surface finish consistency are critical.

Key Features

• CoroMill 390 series cutter body with 90-degree lead angle for true square-shoulder milling
• Accepts 4 R390-11.. indexable inserts with screw clamping for secure, repeatable insert location
• Through-coolant design directs coolant directly to the cutting zone for improved tool life and chip evacuation
• Right-hand cutting direction for standard spindle rotation compatibility
• Steel toolholder body for rigidity and durability in demanding milling operations
• Compact 1-inch cutting diameter suitable for small-feature and tight-clearance work

Compatibility

Compatible with R390-11.. style indexable inserts. Designed for use with arbors matching a 0.9646-inch hole diameter. Refer to SANDVIK COROMANT CoroMill 390 series insert selection guides for compatible insert grades and geometries.

Installation Notes

Installation should be performed by a qualified machinist familiar with indexable milling toolholders. Ensure the machine spindle is fully stopped and locked out before mounting or changing the cutter body or inserts. Verify arbor fit and confirm all insert screws are torqued per the insert manufacturer's tooling guidelines before initiating a cut. Through-coolant lines should be checked for proper connection and flow before beginning operation.
