Sandvik Coromant 5740563 RCMT43 H13A Carbide Turning Insert

Product Description

The SANDVIK COROMANT 5740563 is a solid carbide turning insert in the RCMT43 H13A designation, part of the CoroTurn 107 series. It features a round insert shape with a 1/2 inch inscribed circle and a thickness of 0.1875 inches (3/16 inches). The insert is uncoated (bright finish) with a 7-degree relief angle and a neutral hand orientation. With four available cutting edges and screw-style insert holding, it is suited for precision turning operations on CNC lathes and turning centers. Licensed machinists and CNC operators typically install and index these inserts during production or maintenance cycles.

This insert is designed primarily for turning steel workpieces and is also rated for use on stainless steel. It fits into toolholders compatible with the RCMT 12 04 00 insert geometry per ISO designation. The CoroTurn 107 series is engineered for external and internal turning where a round insert profile is appropriate, providing consistent chip formation across a range of feed rates and depths of cut.

Installation Notes

Indexing and replacement of turning inserts should be performed by a qualified machinist or CNC operator with the machine fully stopped and in a safe, locked-out state. Use the appropriate torque driver or insert screw tool specified for the CoroTurn 107 toolholder to secure the insert - do not overtighten or use improvised tools. Inspect the insert pocket and clamping screw for wear or damage before seating a new insert. Follow the toolholder manufacturer guidelines for proper seating depth and clamping sequence.
