Sandvik Coromant 5745385 Milling Insert K20D Carbide

Product Description

The SANDVIK COROMANT 5745385 is a solid carbide milling insert designed for use in R365 series face and shoulder milling cutters. Carrying manufacturer grade K20D and material grade K15, this double-sided square insert features a CVD-applied TiCN and Al2O3 coating that delivers wear resistance and thermal stability in demanding cutting applications. The insert measures 5.66 mm thick with an inscribed circle of 15.00 mm and provides 8 cutting edges per insert, making it a cost-effective choice for high-volume machining operations. The KM chip breaker geometry and 0.30 mm corner radius support consistent chip control across a range of feed rates.

This insert is engineered for machining cast iron workpieces, covering primary material code K, and is well suited to both roughing and semi-finishing passes in that material class. The right-hand cutting configuration and negative rake geometry are standard for R365 toolholders used in CNC machining centers across automotive, general engineering, and heavy manufacturing environments. Maximum depth of cut is 6.00 mm. The ANSI and ISO code for this insert is R365-1505ZNE-KM K20D, and the insert size code is 1505.

Key Features

Installation Notes

This insert is installed and replaced by a machinist or CNC toolroom technician. Power down and lock out the machine spindle before changing inserts. Use the appropriate Torx or insert-clamping screw driver specified by the toolholder manufacturer — do not overtighten or cross-thread the clamping screw. Inspect the insert seat and clamping screw for wear or debris before seating the new insert.
