Sandvik Coromant 5853548 Round Milling Insert S30T

Product Description

The SANDVIK COROMANT 5853548 is a solid carbide round milling insert in the RCKT series, designed for high-performance milling of stainless steel, superalloys, and titanium. Carrying the manufacturer grade S30T and coated with TiAlN via a PVD process, this insert delivers wear resistance and thermal stability under demanding cutting conditions. The round RCKT insert shape provides 8 cutting edges per insert with a positive rake geometry and a PM chip breaker, supporting consistent chip control in difficult-to-machine materials. At 0.25 inches thick with an inscribed circle of 0.6299 inches, it fits the RCKT 16 06 M0-PM insert pocket standard. Installation is performed by licensed machinists and CNC tooling specialists.

This insert is suited for milling operations on stainless steel (ISO material code M) and superalloys and titanium (ISO material code S) in both production and job-shop environments. The PM chip breaker geometry and positive rake are optimized for these work materials, reducing cutting forces and heat generation at the insert edge. Compatible cutter series include 391.68S, C5-SRDC, C5-SRSC, C6-SRDC, and C6-SRSC. Typical applications include face milling, shoulder milling, and contour milling where consistent edge life and chip control are priorities. The insert is held in the cutter body by a screw-clamp method, standard for RCKT-style toolholders.

Installation Notes

Installation is performed by a qualified machinist or CNC tooling technician. Always power down and lock out the machine spindle before changing inserts. Use the correct Torx or hex key for the insert clamping screw and follow the cutter body manufacturer's seating procedure to ensure full pocket contact. Inspect the insert pocket and screw threads for damage before installing a new insert.
