Sandvik Coromant 5752559 Turning Insert TCMT221PM 1525

Product Description

The SANDVIK COROMANT 5752559 is a cermet turning insert in the TCMT style, designed for precision external turning operations on CNC and manual lathes. Manufactured under the CoroTurn 107 series, it carries grade 1525 cermet substrate with a PVD-applied TiCN and TiN multilayer coating that provides wear resistance and edge stability at elevated cutting speeds. The insert has a 60-degree triangular shape with a neutral hand orientation, a 0.4228-inch insert length, and a 1/64-inch (0.0157-inch) corner radius suited to finish and semi-finish turning. Relief angle is 7 degrees. This insert is installed by machinists and CNC tool setters in production and job-shop environments targeting steel and similar ISO P-class workpiece materials.

The 5752559 is intended for light to medium-duty continuous turning passes on ISO P primary workpiece materials, including carbon steels and alloy steels. The CoroTurn 107 series is designed for screw-clamped toolholders using the TCMT insert pocket geometry. A maximum depth of cut of 0.4071 inches (10.34 mm) applies in typical application. The PM chip breaker geometry supports controlled chip formation during finishing and semi-finishing passes where tight tolerances and surface finish are priorities.

Installation Notes

Insert installation and indexing should be performed by a qualified machinist or CNC tool setter with the machine powered off and the spindle locked. Use the correct Torx or hex key for the clamping screw torque specified by the toolholder manufacturer — do not substitute fasteners. Inspect the insert pocket and seating surface for chips or contamination before seating the insert. Dispose of worn inserts in accordance with applicable shop safety and waste-handling procedures.
