Sandvik Coromant 5751902 Turning Insert Coroturn 107

Product Description

The SANDVIK COROMANT 5751902 is a TCMT-style triangular turning insert engineered for precision metal cutting in CNC and manual turning applications. This insert features a 60-degree included angle and a CVD-applied multilayer coating of TiCN, Al2O3, and TiN over a solid carbide substrate, delivering wear resistance and thermal stability during continuous and interrupted cuts. The MM chip breaker geometry is optimized for stainless steel workpieces, controlling chip flow and reducing built-up edge. With a neutral hand orientation and screw-holding method, this insert fits standard TCMT toolholders used in production turning environments. It is part of the CoroTurn 107 series and carries the ISO designation TCMT 09 02 04-MM 2025.

This insert is intended for turning stainless steel (ISO material group M) in both light and medium stock-removal operations. The CoroTurn 107 series targets boring, external, and internal turning where secure insert clamping and close-tolerance finishes are required. The 1/64 inch corner radius makes it suitable for finishing and semi-finishing passes where surface quality and edge detail matter. Machinists and CNC operators working in job shops, aerospace component production, and general metalworking will encounter this insert in high-precision turning programs.

Key Features

• CVD multilayer coating: TiCN, Al2O3, and TiN for extended tool life on stainless steel
• 60-degree triangular insert shape with 3 usable cutting edges per insert
• MM chip breaker geometry engineered for stainless steel chip control
• Screw-clamp holding method (Clearance Code C, Tolerance Code M) for rigid, repeatable seating
• Neutral hand orientation compatible with standard TCMT toolholder configurations
• CoroTurn 107 series — designed for boring and external turning with close tolerances

Compatibility

Designed as an OEM-specification insert for SANDVIK COROMANT CoroTurn 107 series toolholders accepting TCMT-style inserts. ISO designation TCMT 09 02 04-MM 2025 can be used to cross-reference compatible toolholder bodies. No additional compatible model numbers were specified in the available product data.

Installation Notes

Insert replacement and seating should be performed by a qualified machinist or CNC operator with the machine in a stopped, locked-out state per OSHA lockout/tagout requirements. Ensure the insert pocket and clamping screw are free of chips and debris before seating the insert. Use the manufacturer-specified torque driver for the clamping screw — do not over-torque or substitute fasteners. Inspect the insert seat and toolholder pocket for wear each time inserts are rotated or replaced.
