Sandvik Coromant 7080834 Turning Insert DNMG432-PM 4335

Product Description

The SANDVIK COROMANT 7080834 is a DNMG-style solid carbide turning insert designed for precision metal cutting on CNC lathes and turning centers. It carries a CVD-applied multilayer coating of TiCN, Al2O3, and TiN, which provides thermal resistance and wear protection during continuous and interrupted cuts. The insert features a neutral hand orientation, a 55-degree diamond shape, a 1/2-inch inscribed circle, and a 1/32-inch corner radius. With four available cutting edges and a PM chip breaker geometry, it is suited for productive turning operations on steel workpieces. It is installed and managed by machinists and CNC tooling technicians working in production or job-shop environments.

This insert is intended for external and internal turning applications where consistent chip control on steel is required. The PM chip breaker geometry targets medium-depth finishing to moderate roughing passes on carbon and alloy steels, aligning with ISO material group P. It is part of the T-Max P series, which is engineered for high-productivity turning with reliable edge life. The insert seats in standard DNMG-compatible toolholders using clamp and pin holding methods, making it a direct fit for common indexable turning setups found in both manual and automated machining cells.

Key Features

• CVD multilayer coating: TiCN, Al2O3, and TiN for thermal and abrasion resistance
• 55-degree diamond insert shape with neutral hand for versatile tool path flexibility
• PM chip breaker geometry optimized for steel turning in ISO P material group
• Four cutting edges per insert for extended tooling value
• Clamp and pin holding method compatible with standard DNMG toolholders
• ISO code DNMG 15 04 08-PM 4335 for cross-reference ordering

Compatibility

Designed for use in DNMG-compatible indexable turning toolholders that accept clamp and pin insert retention. Fits standard holders sized for a 1/2-inch inscribed circle DNMG insert with a 0.2030-inch hole diameter.

Installation Notes

Indexable turning inserts are installed and indexed by machinists or CNC tooling technicians. Power down and lock out the machine spindle before seating or indexing the insert. Use the appropriate torque wrench and clamp hardware specified by the toolholder manufacturer — do not over-tighten the clamp screw, as carbide inserts are brittle and can fracture under uneven clamping force. Inspect the insert pocket and seating surfaces for chips or debris before installation to ensure proper insert support and edge alignment.
