Sandvik Coromant 5724945 Turning Insert CCMT431MM 1115

Product Description

The SANDVIK COROMANT 5724945 is a CCMT431MM-geometry carbide turning insert in the CoroTurn 107 series, coated with TiAlN and AlCr2O3 via a PVD process. It carries a manufacturer grade of 1115 and is designed for screw-clamped toolholders requiring a CCMT insert style. The insert features an 80-degree diamond shape, a neutral hand orientation, and a corner radius of 0.0157 inches (0.40 mm), making it suitable for general turning and light finishing operations. Licensed machinists and CNC operators select this insert for precision metal removal where coating integrity and edge consistency are critical.

This insert is primarily engineered for stainless steel workpieces and is also rated for superalloy and titanium applications. It fits screw-clamped toolholders designed for the CCMT insert style within the CoroTurn 107 system. The MM chip breaker geometry is optimized for controlled chip formation during medium-duty turning. Typical applications include external and internal turning on CNC lathes in job shop, aerospace, and industrial manufacturing environments where difficult-to-machine materials are common.

Key Features

• MM chip breaker geometry engineered for stainless steel, superalloy, and titanium turning
• 80-degree diamond insert shape (CCMT style) with neutral hand orientation
• Corner radius of 0.0157 inches (0.40 mm) for precise edge definition
• Screw-clamped insert holding method compatible with CoroTurn 107 toolholders
• 2 cutting edges per insert for extended tool life and cost efficiency

Compatibility

Designed for use with CoroTurn 107 series screw-clamped toolholders accepting CCMT431MM-style inserts. ISO code CCMT120404MM-1115. Primary workpiece material is stainless steel (ISO material code M); secondary rated workpiece materials are superalloy and titanium (ISO material code S).

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the spindle before indexing or replacing inserts. Use the correct torque wrench and Torx key specified for the CoroTurn 107 clamping screw to avoid seat damage — do not overtighten by feel alone. Inspect the insert pocket and seating surface for chips or debris before seating a new insert.
