Sandvik Coromant 5915111 TNMG432-SM 1105 Turning Insert

Product Description

The SANDVIK COROMANT 5915111 is a TNMG432-SM 1105 grade solid carbide turning insert designed for precision metal removal on CNC and manual lathes. Coated with TiAlN via a PVD process, this insert delivers wear resistance and thermal stability in demanding cutting applications. The triangular insert shape provides 6 cutting edges per insert, and the SM chip breaker geometry is engineered for controlled chip formation in difficult-to-machine materials. At 0.252 inches in length with a 0.5-inch inscribed circle and a 0.0313-inch corner radius, it fits standard TNMG toolholders. Installation and setup is handled by machining professionals in production and job-shop environments.

This insert is suited for turning stainless steel as its primary workpiece material, with secondary applications in superalloys and titanium. The SM chip breaker geometry is specifically selected for materials that work-harden or produce stringy chips, making it a practical choice for aerospace, medical, and energy-sector component machining. It is part of the SANDVIK COROMANT T-Max P series and carries ISO designation TNMG 22 04 08-SM 1105. The neutral hand orientation allows use in both right-hand and left-hand toolholder configurations.

Key Features

• TiAlN coating applied via PVD process for improved wear resistance and edge stability
• SM chip breaker geometry optimized for stainless steel, superalloy, and titanium turning
• 6 cutting edges per triangular insert reduce per-edge tooling cost
• Neutral hand insert compatible with right-hand and left-hand toolholders
• Clamp and pin holding method for secure seating in T-Max P compatible toolholders
• 0.0313-inch corner radius balances surface finish quality with edge strength

Compatibility

Designed for use in TNMG-style toolholders within the SANDVIK COROMANT T-Max P series. Compatible with standard TNMG 432 insert pockets using clamp and pin holding. Suitable for turning stainless steel (ISO material group M) and superalloys and titanium (ISO material group S).

Installation Notes

Installation is performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and the toolholder is securely mounted before indexing or replacing inserts. Use the appropriate torx or clamp screw as specified by the toolholder manufacturer when seating the insert. Inspect the insert pocket and clamping components for wear or debris before seating a new edge.
