Sandvik Coromant 5730537 Turning Insert Dcmt Coroturn 107

Product Description

The SANDVIK COROMANT 5730537 is a DCMT-style indexable turning insert designed for precision metal cutting in CNC lathe and turning center applications. Part of the CoroTurn 107 series, this insert features a 55-degree diamond shape with a neutral hand orientation and a 3/8-inch inscribed circle. The carbide substrate is CVD-coated with a multilayer TiCN, Al2O3, and TiN finish under manufacturer grade 2025, providing wear resistance and thermal stability when cutting stainless steel and similar materials. With 2 cutting edges per insert and a 1/32-inch corner radius, it is suited for light to medium finishing passes.

This insert is applied in turning operations targeting stainless steel workpieces, corresponding to ISO workpiece material code M. The CoroTurn 107 series is designed for external turning where the insert is held by a screw clamp mechanism. The DCMT geometry with a 7-degree relief angle and MF chip breaker makes it appropriate for finishing and semi-finishing operations where chip control and surface finish are priorities. It is commonly used in job shops, production machining environments, and maintenance facilities handling precision turned components.

Key Features

• CVD multilayer coating: TiCN, Al2O3, and TiN for extended tool life on stainless steel
• 55-degree diamond insert shape (code D) with 7-degree relief angle for positive cutting action
• MF chip breaker geometry optimized for finishing and semi-finishing passes
• 2 usable cutting edges per insert for cost efficiency
• Screw-held mounting compatible with CoroTurn 107 toolholders
• ISO designation DCMT 11 T3 08-MF 2025 for cross-reference and toolholder matching

Compatibility

Designed for use with CoroTurn 107 series toolholders that accept DCMT-style inserts with a screw holding method. ISO insert code DCMT 11 T3 08-MF 2025 can be used to verify toolholder seat compatibility. Intended primarily for stainless steel (ISO material code M) turning applications.

Installation Notes

Installation is performed by a machinist or CNC tooling technician. Before swapping inserts, ensure the machine spindle is stopped and the tool turret is in a safe indexed position. Use the correct Torx or hex key specified for the CoroTurn 107 screw clamp system and do not overtighten, as this can crack the insert or damage the seat. Inspect the toolholder pocket and seating shim for wear or debris before seating the new insert.
