Seco 03062793 Turning Insert DNMG432-M5 TK1501 Carbide

Product Description

The SECO 03062793 is a DNMG432-M5 series indexable turning insert manufactured from solid carbide and finished with a multilayer CVD coating of TiCN, Al2O3, and Cr under the Duratomic coating classification. Designed with a 55-degree diamond shape, negative rake, and neutral hand, the insert provides four usable cutting edges per body. The M5 chip breaker geometry features a chamfered and honed cutting edge style suited to moderate to heavy material removal. The inscribed circle measures 0.5 inches, insert length is approximately 1.22 inches (15.5 mm), and corner radius is 0.0315 inches (1/32 inch). Clearance code is N, tolerance code is M. Licensed machinists and CNC turning specialists are the primary installers of this insert type.

This insert is optimized for primary use on cast iron (ISO material code K, grades K10, K20, K30) and is also applicable to steel and stainless steel workpieces (ISO codes P and M). The DNMG432-M5 geometry supports multiple turning operations including conventional turning, facing, boring, and back turning. The M5 chip breaker is well suited to moderate cutting depths and stable setups in both production and job-shop environments. The maximum depth of cut is 0.5787 inches, making this insert a practical choice for medium-to-heavy passes on cast iron components. The industry standard number is DNMG432-M5 and the ISO code is DNMG150408-M5.

Key Features

• Multilayer CVD Duratomic coating (TiCN, Al2O3, Cr) for extended tool life on cast iron and steel
• 55-degree diamond insert shape with negative rake and neutral hand orientation
• Four cutting edges per insert body for reduced cost per edge
• M5 chip breaker geometry with chamfered and honed edge for controlled chip formation
• Compatible with clamp, pin, and lever-lock toolholding systems
• Meets ANSI and ISO standards; ISO code DNMG150408-M5

Compatibility

Designed for use in DNMG-style toolholders that accept a 432 insert size (inscribed circle 0.5 inches, thickness 3/16 inch) with clamp, pin, or lever-lock holding methods. Fits toolholders conforming to ANSI and ISO DNMG150408 specifications. Verify toolholder clearance code N and tolerance code M compatibility before installation.

Installation Notes

This insert is installed by a machinist or CNC tooling technician. Power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate torque wrench and insert screw hardware specified by the toolholder manufacturer — do not over-tighten the clamping screw, as carbide inserts are brittle and susceptible to fracture under uneven clamping load. Inspect the insert pocket and clamping surfaces for chips or debris before seating a new insert.
