Sandvik Coromant 5730966 Turning Insert Dcmt Coroturn 107

Product Description

The SANDVIK COROMANT 5730966 is a DCMT-style turning insert engineered for precision metal cutting in demanding machining environments. Part of the CoroTurn 107 series, this insert features a 55-degree diamond shape with a neutral hand orientation and a 7-degree relief angle. It is manufactured from solid carbide and coated via CVD with a TiCN, Al2O3, and TiN multilayer stack using the 2025 grade, making it well suited for cutting stainless steel and other difficult-to-machine alloys. The MF chip breaker geometry supports light to medium finishing passes where tight chip control is required.

This insert is designed for external and internal turning operations on CNC lathes and turning centers. Its primary application is stainless steel (ISO material group M), though the 2025 grade CVD coating offers broad capability across similar work materials. The CoroTurn 107 series is a screw-clamped insert system commonly used in light-to-medium finish turning where dimensional accuracy and surface quality are priorities. Licensed machinists and CNC operators install this insert in production and job-shop environments.

Key Features

• 55-degree diamond (DCMT) insert shape with 7-degree clearance angle for low cutting forces
• CVD-applied TiCN, Al2O3, and TiN multilayer coating in 2025 grade for wear resistance on stainless steel
• MF chip breaker geometry optimized for light to medium finishing cuts and reliable chip control
• Screw-held mounting method compatible with CoroTurn 107 toolholders
• 2 cutting edges per insert for extended tool life per unit
• Neutral hand orientation for flexible use in standard DCMT-compatible toolholders

Compatibility

Designed for use in CoroTurn 107 series screw-clamp toolholders that accept DCMT insert style with a tolerance code M and clearance code C. ISO designation for this insert is DCMT 11 T3 04-MF 2025. Confirm toolholder bore and seat dimensions before installation.

Installation Notes

Insert installation should be performed by a qualified machinist or CNC tooling technician with the machine in a full stop, locked-out condition. Seat the insert firmly into the toolholder pocket and secure the clamping screw to the toolholder manufacturer's specified torque using the appropriate Torx or hex key. Inspect the insert seat for chips or debris before seating to prevent insert rocking or premature edge failure. Never exceed the recommended depth of cut or feed rate for the 2025 grade as specified in the SANDVIK COROMANT cutting data documentation.
