Sandvik Coromant 5740705 Turning Insert RCMT32.5-SM S05F

Product Description

The SANDVIK COROMANT 5740705 is a round solid carbide turning insert designed for precision metal cutting in CNC turning applications. Designated RCMT32.5-SM S05F, this insert features a multi-layer MTCVD-applied coating of TiCN, Al2O3, and TiN for wear resistance and thermal stability at the cutting edge. It belongs to the CoroTurn 107 series and is engineered for screw-clamped toolholders. With 4 cutting edges, a neutral hand orientation, and a full radius profile, it delivers consistent performance on demanding workpiece materials including superalloys and titanium. Insert thickness is 0.1563 inches and inscribed circle diameter is 0.375 inches.

This insert is suited for external and internal turning operations in production machining environments, particularly where superalloys and titanium alloys are the primary workpiece materials. The SM chip breaker geometry is optimized for these materials, supporting stable chip control under moderate to light cutting conditions. It is commonly used in aerospace and energy sector component machining where tight tolerances and surface finish consistency are required. The CoroTurn 107 system is widely used in ISO S-material turning applications across both horizontal and vertical CNC turning centers.

Key Features

• Round insert shape (RCMT) with full radius edge for smooth turning profiles
• Multi-layer MTCVD coating: TiCN, Al2O3, and TiN for heat and wear resistance
• SM chip breaker geometry optimized for superalloy and titanium turning
• 4 cutting edges per insert for extended tool economy
• Screw-clamped holding method compatible with CoroTurn 107 toolholders
• Neutral hand orientation for flexible setup on standard turning toolholders

Compatibility

Designed for use in CoroTurn 107 series screw-clamped toolholders. ISO code RCMT 09 T3 00-SM S05F. Intended for turning of superalloys and titanium (ISO material code S). Verify toolholder bore and seat dimensions before installation.

Installation Notes

Turning insert replacement is performed by machining technicians with the spindle locked out and all machine motion stopped per machine-specific lockout/tagout procedures. Use the appropriate Torx or hex key to remove and seat the clamping screw to the toolholder manufacturer's specified method without overtightening. Inspect the insert pocket seat for debris or wear before seating the new insert. Confirm cutting edge orientation and hand match the toolholder setup before resuming operation.
