Sandvik Coromant 5853472 Milling Insert S30T R390

Product Description

The SANDVIK COROMANT 5853472 is a solid carbide milling insert in the R390 series, designed for use in square-shoulder milling operations. It carries a TiAlN coating applied via PVD process and is manufactured to grade S30T. The insert features a parallelogram shape with a positive rake angle of 20 degrees and a corner-rounded cutting edge style, producing clean, controlled cuts in demanding materials. With 2 cutting edges, an inscribed circle of 6.80 mm, and a thickness of 3.59 mm, this is a right-hand, single-sided insert held in place by a screw. It is suited for professional machining environments where precision and tool life in difficult alloys are the priority.

This insert is intended for milling stainless steel, superalloys, and titanium — material application codes M and S per ISO classification. The ML chip breaker geometry is optimized for light-to-medium cutting conditions in these tough, work-hardening materials. The R390 series designation and ANSI/ISO code R390-11 T3 16E-ML S30T confirm compatibility with R390-style toolholders and cutter bodies. Typical applications include face milling, shoulder milling, and ramping operations in aerospace, medical, and industrial manufacturing environments. The insert is installed by qualified machinists or CNC setup technicians working with compatible milling systems.

Installation Notes

Installation is performed by a qualified machinist or CNC tooling technician. The machine spindle must be fully stopped and the tool assembly secured before seating or removing inserts. Use the appropriate torx or hex key to tighten the clamping screw to the toolholder manufacturer specification — do not overtighten. Inspect the insert pocket and seating surface for chips or debris before installing a new insert to ensure proper contact and runout.
