Seco 10070637 DNMG432-MF5 Carbide Turning Insert

Product Description

The SECO 10070637 is a DNMG432-MF5 indexable turning insert manufactured from solid carbide with a CVD-applied Duratomic TiCN and Al2O3 multilayer coating. Carrying the TH1501 grade designation, it is engineered for finishing and medium machining of hard materials and cast iron. The insert features a 55-degree diamond (rhombic) shape, a 0.5-inch inscribed circle, and a 0.0315-inch corner radius. With four usable cutting edges and a neutral hand orientation, it delivers consistent tool life in high-wear applications. Licensed machinists and CNC turning specialists working in production or job-shop environments are the primary installers.

This insert is suited for hard turning, facing, boring, and back turning operations on CNC lathes and turning centers. The MF5 chip breaker geometry is optimized for finishing to medium-depth cuts, with a maximum depth of cut of 0.1063 inches. It targets primary workpiece materials classified as hardened materials (H-grade) and is also effective on cast iron (K-grade). The insert is compatible with toolholders that use clamp, pin, or lever-lock holding methods conforming to ANSI and ISO standards for the DNMG insert series.

Key Features

• Duratomic CVD coating: TiCN plus Al2O3 multilayer for wear resistance and toughness on hardened materials
• 55-degree diamond insert shape with 0.0315-inch corner radius for stable entry angles and reduced radial forces
• MF5 chip breaker geometry rated for finishing and medium machining operations
• Four cutting edges with chamfered and honed edge prep for consistent performance across all edges
• Neutral hand orientation fits both right-hand and left-hand toolholder configurations
• Negative rake and negative side clearance design for rigid clamping and maximum insert support

Compatibility

Designed for use with DNMG-series toolholders accepting clamp, pin, or lever-lock insert retention, conforming to ANSI insert code DNMG432 and ISO insert code DNMG150408. Compatible with multi-use applications including turning, facing, boring, and back turning.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before indexing or replacing inserts. Seat the insert fully in the pocket and confirm the clamp, pin, or lever-lock mechanism is fully engaged before running the machine. Do not exceed the published maximum depth of cut for the MF5 chip breaker geometry.
