Sandvik Coromant 7564438 Milling Insert Grade 4340 R245

Product Description

The SANDVIK COROMANT 7564438 is a square solid carbide milling insert designed for use in R245 series face milling and shoulder milling cutters. It carries grade 4340 with a CVD-applied multilayer coating of TiCN, Al2O3, and TiN, which provides wear resistance across a range of cutting conditions. The insert measures 0.5276 inches inscribed circle diameter and 0.1563 inches thick, with a 1.50 mm corner radius and a positive 5-degree rake angle. It features four cutting edges and a PH chip breaker geometry. Licensed machinists and CNC machine operators use this insert in production environments on steel, stainless steel, and cast iron workpieces.

This insert is suited for applications involving steel, stainless steel, and cast iron, covering ISO material codes P, M, and K with material grades P40, M40, and K40. It handles a maximum depth of cut of 6.50 mm (0.2559 inches), making it appropriate for moderate to semi-heavy face milling passes. The insert is held by screw and fits right-hand cutter bodies in the R245 series. It is applicable to both production shop floor use and contract machining environments where consistent chip control and coating durability are priorities.

Installation Notes

Installation and replacement should be performed by a qualified machinist or CNC tooling technician. Always power down and lock out the machine spindle before changing inserts. Use the appropriate Torx or hex key for the clamping screw and ensure the insert seat is clean and free of chips before seating the new insert. Handle solid carbide inserts with care to avoid chipping the cutting edges.
