Sandvik Coromant 5730844 Turning Insert Dcmt 2025

Product Description

The SANDVIK COROMANT 5730844 is a solid carbide turning insert from the CoroTurn 107 series, designed for external turning and profiling operations on CNC lathes and turning centers. It carries ISO designation DCMT 07 02 04-MM 2025 and features a CVD-applied multilayer coating of TiCN, Al2O3, and TiN for wear resistance and thermal stability. The 55-degree diamond insert shape (code D) provides a sharp, versatile cutting geometry suitable for medium finishing passes. The MM chip breaker geometry is optimized for controlled chip evacuation. This insert is installed by machinists and CNC operators working in precision turning environments.

This insert is rated primarily for stainless steel workpiece material (ISO material code M), making it well suited for turning austenitic and duplex stainless components. Its neutral hand orientation allows use on standard right-hand toolholders. The screw-holding method (ISO clearance code C, tolerance code M) fits standard DCMT-style pockets. The CoroTurn 107 series is commonly used in light to medium turning applications where close tolerances and surface finish are priorities.

Key Features

• CVD multilayer coating: TiCN, Al2O3, and TiN for extended tool life on stainless steel
• 55-degree diamond insert shape with MM chip breaker geometry for controlled chip formation
• Manufacturer grade 2025 optimized for stainless steel (ISO M) materials
• Neutral hand orientation compatible with standard DCMT screw-on toolholders
• 2 cutting edges per insert for cost efficiency
• Screw-on holding method for positive, repeatable seating in the pocket

Compatibility

Designed as an OEM-style replacement insert for DCMT-style toolholders within the SANDVIK COROMANT CoroTurn 107 series. ISO designation DCMT 07 02 04-MM 2025 governs toolholder pocket compatibility. Verify pocket and screw specifications against your toolholder documentation before installation.

Installation Notes

Insert seating and clamping should be performed by a qualified machinist following the toolholder manufacturer's torque and clamping procedure for screw-type inserts. Power down and lock out the spindle before changing inserts. Inspect the toolholder pocket for chips or damage before seating a new insert. Handle carbide inserts with care to avoid chipping the cutting edge prior to use.
