Sandvik Coromant 5745983 Milling Insert H13A Solid Carbide

Product Description

The SANDVIK COROMANT 5745983 is a solid carbide, uncoated milling insert designed for use in R390 series milling cutters. Carrying the H13A manufacturer grade, this parallelogram-shaped insert features a positive 22-degree rake angle and a KM chip breaker geometry, making it well-suited for controlled chip evacuation during face and shoulder milling operations. It measures 0.1875 inches thick with an inscribed circle diameter of 0.3780 inches and a corner radius of 0.0157 inches. With two cutting edges per insert and a right-hand orientation, it is installed and replaced by machinists and CNC tooling technicians in production and job-shop environments.

This insert is intended for milling cast iron, non-ferrous metals, and superalloys including titanium. It is classified under material grades K20, N15, and S20, aligning with ISO and ANSI workpiece material coding. Typical applications include shoulder milling and face milling operations on machining centers where precise depth of cut control and edge integrity are required. The maximum depth of cut reaches 15.70 mm (0.6181 inches), making it effective for moderate to aggressive passes on compatible work materials. The insert is sold individually with a minimum order quantity of 10 units.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Always power down and lock out the spindle before changing inserts. Use the correct Torx or hex key specified for the R390 cutter body to seat the screw-clamp securely without over-driving. Inspect the insert pocket and seating surfaces for chips or debris before placing a new insert to ensure proper seating and runout control.
