Sandvik Coromant 5725906 Turning Insert Coroturn 111

Product Description

The SANDVIK COROMANT 5725906 is a solid carbide turning insert in the CoroTurn 111 series, designed for precision external and internal turning operations. This CPMT-style insert features a TiAlN and AlCr2O3 dual-layer PVD coating, which provides thermal resistance and wear protection when cutting steel, stainless steel, superalloys, and titanium. The 80-degree diamond shape delivers a strong cutting edge geometry, while the MF chip breaker geometry is optimized for finishing passes on difficult-to-machine materials. The insert uses a screw-clamp holding method and is intended for installation by machinists and CNC turning specialists.

This insert is suited for finishing and semi-finishing turning applications on CNC lathes and turning centers. Its primary workpiece material designation is steel (ISO code P), with secondary suitability for stainless steel, superalloys, and titanium (ISO codes M, P, and S). The MF chip breaker geometry is engineered for consistent chip control at lighter depths of cut and moderate feed rates, making it a practical choice for tight-tolerance surface finish work in production and job-shop environments.

Key Features

• Solid carbide substrate with TiAlN and AlCr2O3 PVD dual-layer coating for heat and wear resistance
• 80-degree diamond insert shape (CPMT style) for strong edge support on profiling and turning passes
• MF chip breaker geometry optimized for finishing cuts on steel, stainless steel, superalloys, and titanium
• Screw-clamp (CPMT) holding method for secure, repeatable seating in compatible toolholders
• Neutral hand orientation suits a wide range of toolholder configurations
• 2 usable cutting edges per insert for extended tool life per unit

Compatibility

Designed for use in CoroTurn 111 series toolholders that accept CPMT-style inserts. ISO code CPMT 09 T3 04-MF 1125. Verify toolholder pocket geometry, seating, and screw specification before installation.

Installation Notes

Insert seating and replacement should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before changing inserts. Use the correct torque driver for the clamping screw to avoid fracturing the carbide or stripping the pocket thread. Inspect the toolholder pocket and seating surfaces for chips or debris before installing a new insert.
