Sandvik Coromant 7080754 Turning Insert Tcmt Coroturn 107

Product Description

The SANDVIK COROMANT 7080754 is a TCMT-style indexable turning insert designed for external turning operations on steel workpieces. It belongs to the CoroTurn 107 series and features a 60-degree triangular insert shape with three cutting edges, delivering reliable performance in general-purpose turning applications. The insert is manufactured from solid carbide and coated via CVD with a TiCN, Al2O3, and TiN multilayer coating system under manufacturer grade 4335. Key geometry specs include a 1/4-inch inscribed circle, a 1/64-inch corner radius, and a 3/32-inch insert thickness. It uses a UM chip breaker geometry and is held in place by a screw-type clamping method.

This insert is suited for steel turning applications in both production and job-shop environments. The UM chip breaker geometry targets light-to-medium finishing cuts where consistent chip control and surface finish are priorities. It is typically used in CNC turning centers and manual lathes with compatible TCMT toolholders. The neutral hand orientation makes it adaptable to a range of toolholder configurations. The CoroTurn 107 series is a common platform for external profiling and light-duty turning where insert security and edge consistency are critical.

Key Features

• CVD-applied TiCN, Al2O3, and TiN multilayer coating for wear resistance on steel
• 60-degree triangular shape provides three usable cutting edges per insert
• UM chip breaker geometry optimized for finishing and light-to-medium turning cuts
• Screw-type insert holding method for positive clamping and repeatable edge location
• 1/64-inch corner radius for fine surface finish requirements
• Grade 4335 carbide substrate suited as primary application for steel (ISO P workpiece material)

Compatibility

Designed for use in TCMT-compatible toolholders within the CoroTurn 107 series platform. ISO code TCMT 11 02 04-UM 4335 can be used to identify compatible toolholder seats. Consult toolholder documentation to confirm seat geometry and clamping configuration before installing.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Power down and lock out the machine before indexing or replacing inserts. Use the correct torque screwdriver for the screw-type clamping system to avoid seat damage or insert breakage. Inspect the insert pocket and clamping screw for wear or debris before seating a new insert.
