Sandvik Coromant 5746853 Milling Insert H13A Solid Carbide

Product Description

The SANDVIK COROMANT 5746853 is a solid carbide milling insert in the R390 series, designed for high-precision face and shoulder milling operations. It carries a parallelogram shape with a right-hand cutting orientation, two usable cutting edges, and a bright uncoated finish in manufacturer grade H13A. The inscribed circle measures 0.378 inches (9.60 mm), thickness is 0.1875 inches (4.76 mm), and the corner radius is 0.0315 inches (0.80 mm). The KL chip breaker geometry and 22-degree positive rake angle promote clean chip evacuation and reduced cutting forces across a range of demanding workpiece materials.

This insert is intended for use in R390 series milling cutters. It is suited for machining cast iron, non-ferrous metals, and superalloys including titanium, corresponding to ISO material groups K, N, and S. Typical applications include face milling, shoulder milling, and pocket milling in both production and job-shop environments. Installation requires pairing with a compatible R390 cutter body and securing via the screw-hold clamping method. The maximum depth of cut reaches 16.00 mm (0.6299 inches), making this insert appropriate for medium to full-depth passes in precision CNC setups.

Installation Notes

This insert is installed and serviced by trained machinists or CNC tooling specialists. Always power down and lock out the machine spindle before changing inserts. Secure the insert using the appropriate torx or hex key as specified by the cutter body manufacturer for the screw-hold clamping system. Inspect the cutter pocket seating surface for debris or wear before seating a new insert to ensure correct edge positioning.
