Tungaloy 6803410 DNMG432-SS GH330 Turning Insert

Product Description

The TUNGALOY 6803410 is a DNMG-style coated carbide turning insert designed for precision metal cutting in CNC lathe and turning center applications. Manufactured to ANSI and ISO standards under the ISO code DNMG 432 SS, this insert features a 55-degree diamond shape with a negative rake geometry and a TiCNO coating applied via PVD process. The GH330 grade targets steel, stainless steel, and cast iron workpieces across material grades P15, P30, M15, M30, K05, and K30. It is installed by machinists and CNC operators performing turning, facing, boring, back turning, and back boring operations.

This insert is suited for production and job-shop environments running moderate-to-general-purpose cuts on steel and stainless steel components. The SS chip breaker geometry is engineered for controlled chip flow in these materials. With four cutting edges per insert and compatibility with both clamp and pin holding methods, it delivers consistent performance across high-volume turning cycles. It fits standard DNMG-SS toolholders and is a direct replacement for other DNMG 432 SS inserts conforming to the same ISO specification.

Key Features

• SS chip breaker for controlled chip formation on steel and stainless steel
• Four usable cutting edges per insert; neutral hand orientation
• Honed cutting edge style for improved edge strength and finish
• Rated for turning, facing, boring, back turning, and back boring operations

Compatibility

Designed as an OEM-style replacement for DNMG 432 SS inserts conforming to ANSI and ISO standards; fits standard DNMG-SS toolholders that accept clamp and pin holding methods.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate torque wrench and clamp hardware specified by the toolholder manufacturer - do not overtighten or undertighten the clamp screw. Inspect the insert seat and pocket for chips or debris before seating the new insert to ensure proper contact and runout.
