Sandvik Coromant 7231364 Turning Insert Dcmt 2220

Product Description

The SANDVIK COROMANT 7231364 is a solid carbide turning insert in the DCMT style, designed for precision external turning operations on CNC lathes and turning centers. Manufactured in the CoroTurn 107 series, it carries a CVD-applied multilayer coating of TiCN, Al2O3, and TiN, optimized for heat and wear resistance during continuous cuts. The insert features a 55-degree diamond shape, a 1/4-inch inscribed circle, a 1/32-inch corner radius, and a neutral hand orientation. Grade 2220 is formulated for cutting stainless steel and similar difficult-to-machine materials where edge integrity and coating adhesion are critical.

This insert is suited for medium to finish turning passes on stainless steel workpieces in both production shop and job shop environments. The MM chip breaker geometry is intended for light to moderate depths of cut where chip control on ductile materials is a priority. Licensed machinists and CNC operators working with ISO material group M workpieces will find this insert a direct fit for toolholders accepting DCMT-style inserts with a screw-clamp holding method.

Key Features

• CVD-coated TiCN, Al2O3, and TiN multilayer finish for wear resistance on stainless steel
• 55-degree diamond insert shape (code D) for versatile turning and profiling
• MM chip breaker geometry for effective chip control on ductile and stainless materials
• Screw-clamp holding method with a 0.1102-inch hole diameter for secure seating
• Neutral hand orientation compatible with standard DCMT toolholders
• 2 cutting edges per insert for cost-effective tool management

Compatibility

Designed as an OEM-style replacement insert for toolholders accepting DCMT-style screw-clamped inserts in the CoroTurn 107 series. ISO code DCMT 07 02 08-MM 2220 identifies the exact seat geometry required. Verify toolholder pocket geometry and insert size code 21.52 before installation.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before indexing or replacing inserts. Use the correct torque screwdriver for the clamp screw to avoid seat damage or insert fracture — do not exceed the toolholder manufacturer's specified clamp torque. Inspect the toolholder pocket for wear or debris before seating a new insert.
