Sandvik Coromant 5853492 Milling Insert S30T R390

Product Description

The SANDVIK COROMANT 5853492 is a single-sided, solid carbide milling insert in the R390 series, designed for high-performance shoulder and face milling operations. It carries a TiAlN PVD coating and an S30T manufacturer grade, making it well suited for cutting stainless steel, superalloys, and titanium. The insert features a parallelogram shape with a 90-degree included angle, two cutting edges, a positive rake geometry, and a rounded corner style with a 0.80 mm corner radius. The ML chip breaker controls chip flow efficiently during light-to-medium cutting passes. Installed by CNC machinists and tooling professionals, this insert mounts via screw-holding into compatible R390 cutter bodies.

This insert is intended for milling applications on difficult-to-machine materials including stainless steel, superalloys, and titanium. It is classified under ISO and ANSI material grades M25 and S25, reflecting its suitability for austenitic stainless and high-temp alloy workpieces. The right-hand cutting geometry and ML chip breaker make it a practical choice for medium-finish and semi-finish passes where chip control and edge stability matter. The ANSI and ISO code for this insert is R390-17 04 08E-ML S30T. It is packaged individually with a minimum order quantity of 10 units.

Installation Notes

Installation is performed by CNC machinists or toolroom professionals. Ensure the cutter body is removed from the spindle and the machine is fully powered down and locked out before changing inserts. Use the correct screw-torque tool as specified by the cutter body manufacturer — do not over-torque the insert clamping screw. Inspect the insert pocket seating surface for debris or damage before seating the new insert.
