Sandvik Coromant 5915102 Turning Insert TNMG332-SM 1115

Product Description

The SANDVIK COROMANT 5915102 is a TNMG332-SM 1115 grade solid carbide turning insert designed for precision metal-cutting applications on CNC lathes and turning centers. Featuring a TiAlN and AlCr2O3 dual-layer PVD coating, this triangular insert delivers high wear resistance and thermal stability when machining difficult-to-cut materials. With a 3/8-inch inscribed circle, a 1/32-inch corner radius, and a neutral hand orientation, it is engineered for consistent performance across moderate to high-speed turning passes. Machinists and CNC operators install this insert as part of the T-Max P series tooling system.

This insert is primarily intended for turning stainless steel, with secondary suitability for superalloys and titanium — materials common in aerospace, medical, and energy sector components. The SM chip breaker geometry manages chip formation effectively in these tough materials, reducing built-up edge and improving surface finish. It fits standard TNMG-compatible toolholders and is appropriate for both roughing and finishing passes depending on feed and depth-of-cut parameters. Production environments running high-mix, difficult-material turning programs will find this insert well-suited to maintaining tool life consistency.

Key Features

• TNMG332-SM geometry with SM chip breaker optimized for stainless steel and superalloy turning
• TiAlN and AlCr2O3 dual-layer PVD coating for elevated wear resistance and thermal protection
• 1115 manufacturer grade carbide substrate for toughness in demanding cut conditions
• Neutral hand orientation compatible with standard TNMG toolholder setups
• 6 cutting edges per insert for extended tool economy
• Clamp and pin holding method for secure, repeatable seating in the toolholder pocket

Compatibility

Designed for use in TNMG-style toolholders within the SANDVIK COROMANT T-Max P series system. ISO code TNMG 16 04 08-SM 1115 may be used to cross-reference compatible toolholder seats and clamp styles.

Installation Notes

Installation is performed by a machinist or CNC tooling technician. Power down and lock out the machine spindle before changing inserts. Seat the insert fully in the toolholder pocket and secure using the designated clamp and pin hardware — do not overtighten the clamp screw beyond toolholder manufacturer specifications. Inspect the insert seat and clamp for wear or debris before installing a new insert to ensure proper contact and edge geometry repeatability.
