Sandvik Coromant 5752575 Turning Insert Tcmt Coroturn 107

Product Description

The SANDVIK COROMANT 5752575 is a TCMT-style indexable turning insert in the CoroTurn 107 series, designed for external turning and boring operations on CNC lathes and turning centers. It features a 60-degree triangular geometry with a 3/8 inch inscribed circle, a 1/64 inch corner radius, and a 7-degree relief angle. The insert is manufactured from solid carbide and carries a dual-layer TiAlN and AlCr2O3 coating applied via PVD process. The UM chip breaker geometry is engineered for light-to-medium finishing cuts. Screw clamping holds the insert in place during operation. Three usable cutting edges are available per insert.

This insert is suited for turning steel and stainless steel in finishing and semi-finishing applications. The UM chip breaker promotes efficient chip control at lower depths of cut and moderate feed rates, making it appropriate for close-tolerance work on steel components. Secondary workpiece material compatibility includes stainless steel, non-ferrous metals, superalloys, and titanium. ISO designation for this insert is TCMT 16 T3 04-UM 1125. It is installed by machinists and CNC operators in production and job-shop environments.

Installation Notes

Insert seating, clamping screw torque, and toolholder condition should be verified before operation. Power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate SANDVIK COROMANT torx or hex key as specified by the toolholder manufacturer for the clamping screw. Inspect the insert pocket and seating surface for chips or debris before seating a new insert edge.
