Sandvik Coromant 5755293 Turning Insert Coroturn 111

Product Description

The SANDVIK COROMANT 5755293 is a solid carbide turning insert designed for precision metal removal in CNC and manual turning operations. Manufactured to the ISO designation TPMT 09 02 04-MF 2015, this insert features a triangular shape with a 60-degree included angle and a positive 11-degree relief angle. The triple-layer TiCN, Al2O3, and TiN coating provides wear resistance and thermal barrier performance suited to demanding cutting conditions. With a 0.2188-inch inscribed circle and a 0.0157-inch corner radius, this insert delivers fine-finish geometry on tight-tolerance workpieces. It is installed by screw-holding and is intended for use by machinist and turning center technicians working in production environments.

This insert is optimized for turning stainless steel workpieces, corresponding to ISO material code M. The MF chip breaker geometry is engineered for medium to fine finishing passes where chip control and surface finish quality are critical. The CoroTurn 111 series is typically applied in external and internal turning applications on lathes and turning centers where consistent edge performance and insert interchangeability are required. The neutral hand orientation makes it suitable for standard right-hand tool holders compatible with the TPMT insert style.

• Screw-holding mounting method for secure, repeatable seating in compatible tool holders
• Maximum depth of cut of 0.374 inches supports a range of finishing pass depths

Compatibility

Designed as an OEM-style replacement for TPMT-style turning insert seats in CoroTurn 111 series tooling. Compatible with tool holders dimensioned for a TPMT insert style with a 0.2188-inch inscribed circle and screw-holding retention. Consult your tool holder documentation to confirm insert size code 1.81.51 fitment before installation.

Installation Notes

Turning insert replacement is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before indexing or replacing inserts. Use the correct torque wrench and insert screw specified by the tool holder manufacturer to seat the insert without cracking the carbide substrate. Inspect the insert pocket for debris or damage before seating a new insert, and never reuse damaged or worn insert screws.
