Sandvik Coromant 6428123 Milling Insert R365 Solid Carbide

Product Description

The SANDVIK COROMANT 6428123 is a solid carbide milling insert designed for face and shoulder milling operations in ferrous materials. It carries a triple-layer CVD coating of TiCN, Al2O3, and TiN under manufacturer grade 3330, which provides thermal resistance and wear protection during extended cuts. The insert features a square shape with a negative rake angle and a corner radius of 0.30 mm (0.0118 inches). With 8 cutting edges and a double-sided configuration, this insert delivers a high number of usable edges per unit, supporting cost-effective tooling management in production environments. Licensed machinists and CNC operators are the typical end users.

This insert is engineered primarily for cutting cast iron (ISO material code K). It fits the R365 cutter series and is used in horizontal and vertical milling centers performing shoulder milling, face milling, and ramping applications. The KM chip breaker geometry is suited to stable, moderate-feed conditions in cast iron components common in automotive, heavy equipment, and general machining operations. The insert is right-hand oriented and is secured by screw clamping in compatible toolholders.

Key Features

• Triple-layer CVD coating: TiCN, Al2O3, TiN — grade 3330 for cast iron applications
• Double-sided square insert with 8 usable cutting edges
• Corner radius of 0.30 mm for controlled edge engagement
• Maximum depth of cut of 6.00 mm (0.2362 inches)
• Negative rake geometry with KM chip breaker for stable cast iron removal
• ANSI and ISO coded: R365-1505ZNE-KM 3330

Compatibility

Compatible with the R365 cutter series. ANSI and ISO code R365-1505ZNE-KM 3330 confirms fitment in R365 screw-clamping toolholders designed for 15 mm inscribed circle, size code 1505 inserts.

Installation Notes

Installation is performed by licensed machinists or CNC tooling technicians. Power down and lock out the machine spindle before seating or replacing inserts. Use the appropriate torque screwdriver specified for the toolholder to secure the clamping screw — do not overtighten or use impact tools on insert screws. Inspect the insert pocket and seating surface for chips or debris before installing a new insert.
