Sandvik Coromant 5740553 Turning Insert Round Coroturn 107

Product Description

The SANDVIK COROMANT 5740553 is a round carbide turning insert in the RCMT style, designed for precision external turning operations on difficult-to-machine materials. It features a multilayer CVD coating of TiCN, Al2O3, and TiN over a solid carbide substrate, applying manufacturer grade S05F. The insert carries an SM chip breaker geometry and a neutral hand orientation. With a 0.5 inch inscribed circle and 0.1875 inch thickness, this insert fits screw-on toolholders and delivers four usable cutting edges per unit. It is suited for licensed machinists and tooling technicians working in production or job-shop CNC turning environments.

This insert is part of the CoroTurn 107 series and is engineered specifically for superalloy and titanium workpieces, material code S. These materials are common in aerospace, oil and gas, and medical component machining where tool life and thermal resistance are critical. The SM chip breaker is optimized for light-to-medium depth-of-cut passes on heat-resistant alloys. The insert is catalogued under ISO code RCMT 12 04 00-SM S05F, which allows cross-reference against standard toolholder designation charts used in CNC turning centers.

Key Features

• Round RCMT insert shape with 4 cutting edges for maximum indexing economy
• CVD multilayer coating: TiCN, Al2O3, and TiN for heat and wear resistance on tough alloys
• S05F grade optimized for superalloy and titanium cutting applications
• SM chip breaker geometry suited for light-to-medium passes on high-temperature alloys
• Screw-on insert holding method with 0.1732 inch hole diameter
• ISO designation RCMT 12 04 00-SM S05F for straightforward toolholder matching

Compatibility

Designed for use in CoroTurn 107 series screw-clamping toolholders that accept round RCMT-style inserts with a 0.5 inch inscribed circle. Compatible with CNC turning centers machining superalloy and titanium workpieces per ISO material code S.

Installation Notes

Installation is performed by qualified CNC tooling technicians. Power down and lock out the machine spindle before indexing or replacing inserts. Use the correct torque wrench and screw per the toolholder manufacturer specification sheet - do not overtighten the clamping screw, as this can fracture the insert. Verify insert seating and shim condition before resuming cuts.
