Sandvik Coromant 5744485 R300 Round Milling Insert

Product Description

The SANDVIK COROMANT 5744485 is a solid carbide round milling insert designed for use in R300-series face and shoulder milling cutters. It carries a manufacturer grade of 2040 and is CVD-coated with a TiCN, Al2O3, and TiN multilayer coating for extended tool life across demanding cutting applications. The insert measures 0.5 inches in inscribed circle diameter and 0.1563 inches thick, with a 0.25-inch corner radius and six available cutting edges. The neutral hand orientation and positive rake geometry make it well suited for moderate to high material removal rates in steel, stainless steel, and superalloy applications.

This insert is intended for use in round-insert milling cutters operating in the R300 and RA300 cutter series. It is a single-sided insert held in place by a screw, with a rounded cutting edge style and MM chip breaker geometry. Typical applications include face milling, shoulder milling, and profiling operations on steel, stainless steel, and superalloys including titanium-based materials. It is suited for production machining environments where ISO material grades P45, M40, and S30 are commonly referenced by CNC machinists and tooling engineers.

Installation Notes

Installation is performed by CNC machinists or tooling technicians during setup or insert indexing. Power down and lock out the machine spindle before servicing the cutter body. Use the appropriate torx or hex key as specified by the cutter body manufacturer for the insert clamping screw. Inspect the insert pocket and clamping screw for wear or damage before seating a new insert.
