Sandvik Coromant 5853473 Milling Insert S30T Carbide R390

Product Description

The SANDVIK COROMANT 5853473 is a solid carbide milling insert designed for high-performance metal removal in demanding machining applications. Carrying the S30T manufacturer grade and coated with TiAlN via a PVD process, this insert delivers wear resistance and thermal stability when cutting stainless steel, superalloys, and titanium. It belongs to the R390 series and carries insert size code 11T316. The parallelogram-shaped, single-sided insert features a positive rake angle of 25 degrees and a corner-rounded cutting edge style, with a 1.60 mm corner radius. Holding is via screw, and the insert is right-hand orientation. Two cutting edges are available per insert.

This insert is engineered for use in R390 and M-32 cutter series toolholders in face milling, shoulder milling, and pocket milling operations. Primary workpiece materials are stainless steel, superalloys, and titanium, corresponding to ISO material groups M and S. It is suited for both production shop and maintenance machining environments where consistent edge life and predictable chip control are required. The PM chip breaker geometry supports controlled chip evacuation during interrupted and continuous cuts in these difficult-to-machine alloys. Installation is performed by machinists and CNC tooling technicians in precision machining shops.

Key Features

• S30T grade solid carbide substrate with TiAlN PVD coating for heat and wear resistance in M and S material groups
• Positive rake angle of 25 degrees reduces cutting forces on stainless steel, superalloys, and titanium
• PM chip breaker geometry promotes controlled chip formation and evacuation
• Corner-rounded cutting edge with 1.60 mm corner radius reduces edge chipping during entry and exit
• Right-hand, single-sided insert with 2 cutting edges per insert for cost-effective indexing
• Screw-mount insert holding method ensures secure seating under high cutting loads
• Conforms to ANSI and ISO standards; ANSI/ISO code R390-11 T3 16M-PM S30T

Compatibility

Compatible with R390 and M-32 cutter series toolholders as stated by the manufacturer. Verified compatible cutter series designations from input data are M-32 and R390.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before indexing or replacing inserts. Use the correct torque driver for the insert clamping screw to ensure proper seating without stripping the screw thread. Inspect the insert pocket and seating surface for chips or debris before installing a new insert, as contamination can cause premature edge failure or vibration.
