Sandvik Coromant 5730641 Turning Insert 55 Diamond 3/8 Inch Ic

Product Description

The SANDVIK COROMANT 5730641 is a solid carbide turning insert designed for precision external and internal turning operations. Identified by ISO code DCMX 11 T3 04-WF 2015, this insert features a 55-degree diamond shape with a 7-degree relief angle and a neutral hand orientation. The WF chip breaker geometry is optimized for stainless steel machining. A CVD-applied multilayer coating of TiCN, Al2O3, and TiN provides wear resistance and thermal stability across a range of cutting conditions. The insert measures 0.442 inches in length with a 3/8-inch inscribed circle and a 0.0156-inch corner radius, and is screw-held for secure positioning in compatible toolholders.

This insert belongs to the CoroTurn 107 series and is intended primarily for machining stainless steel workpieces, corresponding to ISO material group M. It is suited for finishing and semi-finishing passes where controlled chip evacuation and edge integrity are critical. The wiper edge design allows for improved surface finish at standard feed rates without requiring a reduction in depth of cut. Machinists working in production turning environments on CNC lathes will find this insert appropriate for both external diameter and face turning applications where dimensional accuracy is a priority.

Key Features

• 55-degree diamond insert shape with 7-degree relief angle for accessibility in tight cutting profiles
• CVD multilayer coating: TiCN, Al2O3, and TiN for wear and heat resistance
• WF chip breaker geometry optimized for stainless steel ISO group M materials
• Wiper edge included for enhanced surface finish at standard feeds
• Screw-held mounting method for rigid, repeatable insert positioning
• Neutral hand orientation for flexible toolholder compatibility

Compatibility

Designed for use in CoroTurn 107 series toolholders that accept DCMX-style screw-held inserts with a 3/8-inch inscribed circle. Confirm toolholder seat dimensions and clamping configuration before installation. ISO code DCMX 11 T3 04-WF 2015 can be used to cross-reference compatible holders in manufacturer toolholder selection guides.

Installation Notes

Insert replacement should be performed by a qualified machinist with the machine in a stopped, locked-out state per LOTO procedures. Use the correct Torx or hex key at the manufacturer-specified seating torque for the CoroTurn 107 screw-clamp system — refer to the toolholder documentation for that value. Inspect the insert pocket seat for debris or damage before seating the new insert. Never reuse a damaged or chipped insert, as compromised edges can affect workpiece quality and tool life.
