Sandvik Coromant 5724444 CNMG432-MM 1125 Turning Insert

Product Description

The SANDVIK COROMANT 5724444 is a CNMG432-MM 1125 grade solid carbide turning insert designed for external turning operations on CNC lathes and turning centers. It features a TiAlN and AlCr2O3 dual-layer PVD coating that supports high cutting speeds and extended tool life across a range of workpiece materials. The 80-degree diamond shape (C insert shape) provides a strong cutting edge geometry, while the MM chip breaker controls chip flow during medium machining passes. With a 0.5-inch inscribed circle and a 0.0313-inch corner radius, this insert suits precision finishing and medium roughing passes. Machinists and CNC operators install this insert as part of the T-Max P tooling system.

This insert is intended for turning steel as its primary workpiece material, with secondary capability across stainless steel, non-ferrous metals, superalloys, and titanium. It is suited for both production shop environments and job shop turning work where a consistent, wear-resistant insert grade is required. The neutral hand orientation allows use in standard right-hand or left-hand tool holders that accept CNMG geometry. The 4-cutting-edge configuration maximizes cost-per-edge efficiency in high-volume turning applications.

Key Features

• CNMG insert style with 80-degree diamond shape and neutral hand orientation
• TiAlN and AlCr2O3 dual-layer PVD coating for wear and oxidation resistance
• MM chip breaker geometry suited for medium turning passes
• 4 cutting edges per insert for extended usable life
• Clamp and pin insert holding compatible with T-Max P tool holders
• ISO code CNMG 12 04 08-MM 1125 for cross-reference ordering

Compatibility

Designed for use with T-Max P series turning tool holders that accept CNMG insert geometry with clamp and pin holding method. Compatible with applications involving steel, stainless steel, non-ferrous metals, superalloys, and titanium workpiece materials.

Installation Notes

CNC machinists and tool crib technicians install this insert into CNMG-compatible T-Max P tool holders. Power down and lock out the machine spindle before seating or indexing the insert. Use the manufacturer-specified clamp and pin torque procedure outlined in the toolholder documentation. Inspect the insert pocket for chips or wear before seating a new cutting edge to ensure proper clamping and edge stability.
