Sandvik Coromant 5915047 CNMG432-SM 1115 Turning Insert

Product Description

The SANDVIK COROMANT 5915047 is a CNMG432-SM 1115 turning insert designed for precision external turning operations on difficult-to-machine materials. This solid carbide insert features a dual-layer PVD coating of TiAlN and AlCr2O3, delivering high thermal resistance and edge stability under demanding cutting conditions. It carries an 80-degree diamond shape (C), a neutral hand orientation, a 1/2-inch inscribed circle, and a 1/32-inch corner radius. The SM chip breaker geometry is engineered to manage chip control in tough materials. Licensed machinists and CNC lathe operators install this insert in T-Max P toolholders for ISO turning applications.

This insert is intended for primary use on stainless steel (ISO material group M) and is also rated for secondary applications on superalloys and titanium (ISO material group S). These material categories are common in aerospace, medical, and energy-sector component machining. The CNMG format and 432 size code make it compatible with standard CNMG-style toolholders using clamp and pin holding methods. The SM chip breaker geometry supports controlled chip evacuation at moderate to high cutting depths on work-hardening alloys.

Key Features

• TiAlN and AlCr2O3 PVD dual-layer coating for high-temperature wear resistance
• SM chip breaker geometry optimized for stainless steel and superalloy turning
• 80-degree diamond insert shape with 4 cutting edges for extended tool life per insert
• Neutral hand orientation for flexible toolholder compatibility
• Clamp and pin holding method for secure seating under interrupted and continuous cuts
• T-Max P series, ISO code CNMG 12 04 08-SM 1115

Compatibility

Designed for use in CNMG-style T-Max P turning toolholders that accept a 1/2-inch inscribed circle insert with clamp and pin holding. Compatible toolholders must conform to the CNMG 432 insert size and clearance code N with tolerance code M seating requirements.

Installation Notes

This insert is installed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and the toolholder is secured in the turret before seating or replacing the insert. Confirm the clamp and pin mechanism engages correctly to prevent insert movement during cutting. Do not exceed the insert or toolholder manufacturer's recommended cutting parameters for the workpiece material.
