Sandvik Coromant 5915062 Turning Insert DNMG432-SM 1115

Product Description

The SANDVIK COROMANT 5915062 is a DNMG432-SM 1115 series turning insert designed for precision external turning operations on difficult-to-machine materials. This solid carbide insert features a dual-layer TiAlN and AlCr2O3 coating applied via PVD process, providing thermal resistance and edge durability under demanding cut conditions. The 55-degree diamond shape (Insert Shape Code D) delivers strong cutting geometry with four available cutting edges per insert. At 0.252 inches in length with a 0.5-inch inscribed circle and a 0.0313-inch corner radius, this insert is sized for moderate depth-of-cut finishing and semi-finishing passes. It carries a neutral hand orientation and fits standard DNMG toolholders using clamp and pin holding methods.

This insert is engineered primarily for stainless steel (ISO Material Code M) with secondary capability on superalloys and titanium (ISO Material Code S). It is well suited for CNC turning centers and lathes running production or job-shop work where edge consistency and coating life on work-hardening materials are critical. The SM chip breaker geometry is optimized for controlled chip flow and reduced built-up edge on austenitic stainless grades and nickel-based superalloys. Licensed machinists and CNC operators in aerospace, medical, and industrial manufacturing will find this insert appropriate for tight-tolerance turning applications. ISO designation is DNMG 15 04 08-SM 1115.

Key Features

• TiAlN and AlCr2O3 dual-layer PVD coating for thermal stability and wear resistance on stainless and superalloys
• 55-degree diamond insert shape with four cutting edges for cost-effective edge utilization
• SM chip breaker geometry controls chip evacuation on work-hardening and gummy materials
• 0.0313-inch corner radius suitable for semi-finishing and finishing passes with moderate edge strength
• Neutral hand orientation compatible with standard DNMG clamp-and-pin toolholders
• T-Max P series insert from SANDVIK COROMANT, manufactured to ISO tolerance code M, clearance code N

Compatibility

Designed for use in DNMG-style toolholders accepting a 0.5-inch inscribed circle insert with clamp and pin holding. Compatible with toolholders specified for the T-Max P series. Confirm holder pocket geometry and clamping system before installation. No additional model-specific compatibility data was provided in the product input.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician with the machine powered down and in a locked-out state. Ensure the toolholder pocket and clamping surfaces are clean and free of chips before seating the insert. Use a calibrated torque wrench on the clamping screw per the toolholder manufacturer specification - do not over-torque the pin or clamp. Inspect the cutting edge and coating integrity before the first pass; a chipped or contaminated edge on stainless or superalloy work can cause rapid tool failure and surface finish defects.
