Sandvik Coromant 5730589 Turning Insert 55 Diamond 3/8 Ic

Product Description

The SANDVIK COROMANT 5730589 is a DCGT-style solid carbide turning insert from the CoroTurn 107 series, designed for precision external turning and profiling operations. It carries a dual-layer TiAlN and AlCr2O3 coating applied via PVD process, providing wear resistance and thermal stability during cutting. The insert measures 0.442 inches in length with a 3/8 inch inscribed circle, a 5/32 inch thickness, and a 1/64 inch corner radius. The UM chip breaker geometry is engineered for light to medium finishing cuts. Installation is by screw-holding method. This insert is used by CNC machinists and turning center operators in production and job-shop environments.

The 5730589 is suited for turning steel, stainless steel, non-ferrous metals, superalloys, and titanium workpieces. Its 55-degree diamond shape and neutral hand orientation make it a versatile choice for longitudinal turning and light profiling passes. The CoroTurn 107 series is intended for use with compatible screw-clamping toolholders. This insert is particularly effective on ISO material groups P, M, N, and S, with steel listed as the primary workpiece material. Machinists working with difficult-to-machine alloys and close-tolerance finishes will find the UM geometry and PVD coating well matched to their requirements.

Installation Notes

This insert is installed and indexed by CNC machinists or toolroom technicians using a torx or hex key to secure the clamping screw per toolholder manufacturer specifications. Power down and zero-energy-lock the machine before indexing or replacing inserts. Inspect the toolholder pocket seat for chips or damage before seating a new insert. Do not mix insert grades or geometries within the same toolholder without confirming compatibility with the toolholder documentation.
