Sandvik Coromant 7860583 Turning Insert DNMX433-WF 4415

Product Description

The SANDVIK COROMANT 7860583 is a solid carbide turning insert in the T-Max P series, designed for external and internal turning operations on CNC lathes and turning centers. Manufactured to the DNMX 15 04 12-WF 4415 ISO standard, this insert features a 55-degree diamond shape with a neutral hand orientation. The 4415 grade substrate carries a CVD-applied multilayer coating of Al2O3, TiN, and TiCN, delivering thermal resistance and wear protection during medium to heavy steel cutting. The WF chip breaker geometry controls chip flow across a wide range of depths and feed rates. Installed by machinists and CNC operators in production turning environments.

This insert is suited for turning steel and cast iron workpieces in both roughing and semi-finishing passes. The neutral hand design allows use on right-hand or left-hand toolholders depending on setup. The T-Max P series is a high-production external turning platform. With four cutting edges per insert, the 7860583 provides multiple usable edges before replacement, making it a practical choice for high-volume turning cells running steel or cast iron components.

Compatibility

Designed as an OEM-specification turning insert for SANDVIK COROMANT T-Max P series toolholders accepting DNMX-style inserts with clamp and screw holding methods. ISO code DNMX 15 04 12-WF 4415 governs toolholder compatibility. Verify toolholder pocket specifications before installation.

Installation Notes

Turning insert installation and indexing should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine before changing inserts. Seat the insert fully in the pocket and torque the clamp or screw per the toolholder manufacturer specifications. Inspect the insert pocket and seating surface for chips or debris before securing the new edge.
