Sandvik Coromant 5723719 Turning Insert CCMT21.52-MM 1125

Product Description

The SANDVIK COROMANT 5723719 is a solid carbide turning insert in the CCMT21.52-MM 1125 designation, designed for precision external turning operations on CNC lathes and turning centers. It carries a dual-layer PVD coating of TiAlN and AlCr2O3, which provides heat resistance and wear protection at elevated cutting speeds. The insert features an 80-degree diamond shape (Shape Code C), a neutral hand orientation, and an MM chip breaker geometry engineered for controlled chip formation. With a 1/4-inch inscribed circle and a 1/32-inch corner radius, this insert is suited for light-to-medium roughing and finishing passes. Machinists and CNC operators install this insert as part of the CoroTurn 107 series tooling system.

This insert is intended primarily for machining steel (ISO material code P) and is also rated for use on stainless steel (ISO material code M). The CoroTurn 107 series is commonly used in shops running both job-work and production turning on materials in the P and M categories. The screw-holding method provides positive clamping and repeatable indexing, making this insert well suited for automated or high-cycle turning applications where consistent tool life and predictable chip control are priorities. It is a single-insert package sold with a minimum order quantity of 10 units.

Key Features

• PVD-coated TiAlN and AlCr2O3 dual-layer coating for heat and wear resistance at high cutting speeds
• 80-degree diamond insert shape (CCMT) with neutral hand orientation for versatile turning setups
• MM chip breaker geometry for controlled chip evacuation on steel and stainless steel workpieces
• Screw-holding method for positive, repeatable clamping in CoroTurn 107 compatible toolholders
• 2 cutting edges per insert for extended usable tool life per unit
• ISO grade 1125 carbide substrate matched to P and M workpiece material categories

Compatibility

Designed for use in CoroTurn 107 series toolholders accepting CCMT-style inserts with a screw-clamp holding method. Primary workpiece compatibility is steel (ISO code P); secondary workpiece compatibility is stainless steel (ISO code M). ISO designation for this insert is CCMT 06 02 08-MM 1125.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate Torx or hex key as specified by the toolholder manufacturer to seat the clamping screw - do not overtighten by hand estimation. Inspect the insert pocket and seating surface for chips or debris before seating a new insert to ensure proper contact and dimensional accuracy.
