Sandvik Coromant 5732699 Turning Insert DNMG432-MM 2015

Product Description

The SANDVIK COROMANT 5732699 is a DNMG432-MM 2015 grade solid carbide turning insert designed for precision external turning operations on CNC lathes and turning centers. The insert features a CVD-applied multilayer coating of TiCN, Al2O3, and TiN, delivering wear resistance and thermal stability during interrupted and continuous cuts. With a 55-degree diamond shape, a 0.5 inch inscribed circle, and a 1/32 inch corner radius, it is engineered primarily for machining stainless steel. The MM chip breaker geometry controls chip flow across a wide range of cutting conditions. Licensed machinists and CNC turning technicians install this insert in standard DNMG toolholders with clamp and pin holding methods.

This insert is suited for turning stainless steel workpieces in both production and job-shop environments. The ISO code DNMG 15 04 08-MM 2015 and insert size code 432 confirm fitment in compatible DNMG-series T-Max P toolholders. It carries a neutral hand designation, making it appropriate for standard right-hand turning applications. The four available cutting edges per insert reduce per-edge tooling cost in high-volume turning operations. This insert is part of the SANDVIK COROMANT T-Max P series, commonly used in medium to finishing pass applications on austenitic and duplex stainless alloys.

Key Features

• CVD multilayer coating: TiCN, Al2O3, and TiN for thermal and abrasion resistance
• 55-degree diamond insert shape with neutral hand orientation
• MM chip breaker geometry optimized for stainless steel chip control
• Four usable cutting edges per insert for extended tool life economy
• Clamp and pin holding method for rigid, repeatable seating in DNMG toolholders
• Manufacturer grade 2015 targeted at primary workpiece material code M (stainless steel)

Compatibility

Designed for use in DNMG-style T-Max P series toolholders accepting insert size code 432 with clamp and pin holding. Confirmed ISO designation DNMG 15 04 08-MM 2015. Verify toolholder pocket geometry and clamping style before installation.

Installation Notes

Installation is performed by licensed machinists or CNC tooling technicians. Power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate torque wrench per the toolholder manufacturer's clamping screw specification - do not overtighten the clamp pin, as this can fracture the carbide substrate. Inspect the toolholder pocket for chips or burrs before seating the new insert to ensure full contact and correct insert height.
