Sandvik Coromant 5752717 TCMT222MM Turning Insert

Product Description

The SANDVIK COROMANT 5752717 is a TCMT-style triangular carbide turning insert in the CoroTurn 107 series. It carries a dual PVD coating of TiAlN and AlCr2O3, the 1115 manufacturer grade, designed for positive-rake external and internal turning operations on difficult-to-machine materials. The insert measures 10.74 mm (0.4228 inches) in length with a 0.25-inch inscribed circle and a 0.80 mm (1/32 inch) corner radius. It seats via screw clamping and is oriented neutral, making it compatible with standard TCMT toolholders across CNC turning centers and manual lathes used by machinists in production and job-shop environments.

This insert is intended primarily for turning stainless steel, with secondary suitability for superalloys and titanium. These are demanding workpiece materials that generate high heat and require edge stability, which the MM chip breaker geometry and dual-coating system are engineered to handle. Typical applications include finishing and semi-finishing passes on components where surface integrity and controlled chip formation are critical. The 60-degree triangle insert shape provides three usable cutting edges, making it a practical choice for high-volume turning programs where edge economy matters.

Key Features

• PVD-applied TiAlN and AlCr2O3 dual coating for heat resistance and edge wear life on stainless steel and superalloys
• MM chip breaker geometry engineered for controlled chip formation on difficult-to-machine materials
• Three cutting edges per insert from the 60-degree triangle shape
• Screw-clamping insert holding method for rigid, repeatable seating in TCMT toolholders
• 0.80 mm corner radius balances surface finish quality with insert strength
• Maximum depth of cut of 9.94 mm (0.3913 inches) supports semi-finishing applications

Compatibility

Designed for use in TCMT-style screw-on toolholders within the CoroTurn 107 series. ISO code TCMT 11 03 08-MM 1115 identifies the insert geometry for cross-referencing with compatible toolholder systems. Confirm toolholder seat dimensions before installation.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before indexing or replacing inserts. Use the correct torque wrench for the clamping screw to avoid seat damage or insert fracture — refer to the toolholder manufacturer torque specification, as no torque value is specified for this insert. Inspect the toolholder pocket and clamping screw for wear or debris before seating a new insert edge.
