Sandvik Coromant 7231362 Turning Insert DCMT21.51-MF 2220

Product Description

The SANDVIK COROMANT 7231362 is a DCMT-style solid carbide turning insert designed for precision external turning operations. Part of the CoroTurn 107 series, this insert features a CVD-applied multilayer coating of TiCN, Al2O3, and TiN, making it well suited for cutting stainless steel and other difficult-to-machine materials in the M workpiece category. The insert carries a 55-degree diamond shape (Shape Code D), a 7-degree relief angle (Clearance Code C), and a 0.0156 inch (1/64 inch) corner radius. With a neutral hand orientation and a screw-style holding method, it fits standard DCMT toolholders used across CNC turning centers and manual lathes.

This insert is intended for use in turning centers handling stainless steel workpieces where edge stability and wear resistance are critical. The MF chip breaker geometry is optimized for light to medium finishing cuts, producing consistent chip control at moderate feed rates. The ISO designation DCMT 07 02 04-MF 2220 places this insert in a widely used size class for small-to-medium bore and external turning applications in both job shop and production environments. Installation is performed by machinists and CNC setup technicians in metalworking shops.

Key Features

• CVD multilayer coating: TiCN, Al2O3, and TiN for wear and crater resistance on stainless steel
• 55-degree diamond insert shape with 7-degree relief angle for positive cutting geometry
• MF chip breaker optimized for light-to-medium finishing passes
• Screw-style clamping (Hole Diameter: 0.1102 inch / 2.80 mm) for secure seating in DCMT toolholders
• 2 cutting edges per insert for cost-effective indexing
• Tolerance Code M and Clearance Code C for consistent dimensional repeatability

Compatibility

Designed as an OEM-style replacement turning insert for standard DCMT 07 02 04 toolholders compatible with CoroTurn 107 series boring bars and external turning holders accepting screw-clamped DCMT inserts.

Installation Notes

This insert is installed by qualified machinists or CNC setup technicians. Power down and lock out the machine spindle before indexing or replacing inserts. Use the correct Torx or hex key specified for the toolholder screw to avoid stripping the clamp seat. Handle carbide inserts with care to prevent chipping of the cutting edge prior to use.
