Sandvik Coromant 7080715 Turning Insert Carbide Coroturn 107

Product Description

The SANDVIK COROMANT 7080715 is a TCMT-style indexable turning insert from the CoroTurn 107 series, designed for external turning operations on steel workpieces. It is manufactured from solid carbide and finished with a CVD-applied multilayer coating of TiCN, Al2O3, and TiN, which provides wear resistance and thermal protection at the cutting edge. The insert features a 60-degree triangular geometry, a neutral hand orientation, and a PM chip breaker configuration optimized for steel cutting applications. With three cutting edges per insert, it delivers consistent performance across multiple indexing cycles. This insert is installed by machinists and CNC lathe operators in production and maintenance turning environments.

This insert is suited for external turning of steel components in both production and job-shop settings. The TCMT insert style, combined with the CoroTurn 107 series designation, makes it applicable to screw-clamped toolholders configured for TCMT geometry. The PM chip breaker is engineered for medium-duty steel cutting, where chip control and surface finish consistency are priorities. ISO code TCMT 16 T3 04-PM 4335 identifies the full specification for toolholder compatibility verification.

Key Features

• CVD multilayer coating: TiCN, Al2O3, and TiN for wear and heat resistance on steel
• 60-degree triangular insert shape with three indexable cutting edges
• PM chip breaker geometry for controlled chip formation in steel turning
• Neutral hand orientation for flexible toolholder mounting
• Screw-clamp holding method for secure, repeatable insert positioning
• ISO code TCMT 16 T3 04-PM 4335 for cross-reference and toolholder matching

Compatibility

Designed for use with screw-clamp TCMT-style toolholders in the CoroTurn 107 series. ISO code TCMT 16 T3 04-PM 4335 should be used to confirm toolholder compatibility before installation. Primary workpiece material designation is steel (ISO P).

Installation Notes

Insert installation and indexing should be performed by qualified machinists or toolroom personnel with the machine powered off and the spindle locked. Use the appropriate Torx or hex key to torque the clamping screw per the toolholder manufacturer specifications. Inspect the insert pocket and seating surface for chips or debris before seating the insert. Never attempt to index or remove an insert while the machine is running or while the insert is at operating temperature.
