Sandvik Coromant 5853547 Rckt Milling Insert S30T

Product Description

The SANDVIK COROMANT 5853547 is a round solid carbide milling insert in the RCKT series, designed for high-performance metal removal in demanding applications. It carries an S30T manufacturer grade with a TiAlN PVD coating applied for wear resistance and thermal stability at the cutting edge. The insert measures 0.5 inches in diameter (inscribed circle), 0.1875 inches thick, and features a 0.25-inch corner radius with 8 cutting edges. The positive rake geometry and rounded cutting edge style reduce cutting forces. Licensed HVAC and metalworking professionals install this insert in compatible milling cutter bodies using screw-type holding.

This insert is intended for milling stainless steel, superalloys, and titanium workpieces in both roughing and semi-finishing passes. The PM chip breaker designation suits a wide range of feed rates and depths in these difficult-to-machine materials. The maximum depth of cut is 0.0732 inches (1.86 mm). It is a neutral-hand, single-sided insert conforming to ANSI and ISO standards under the code RCKT 13 04 00-PM S30T, making it suitable for use in precision machining environments where consistent chip control is critical.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and lock out the machine spindle before seating or replacing inserts. Use the correct torx or hex key driver to secure the clamping screw to the cutter body; do not overtighten or use impact tools on insert screws. Inspect the cutter pocket and seating surfaces for debris or damage before installing a new insert.
