Seco 03096373 Turning Insert DNMG432-MF2 TP3501 Carbide

Product Description

The SECO 03096373 is a DNMG432-MF2 indexable turning insert in grade TP3501, designed for precision metal removal on CNC lathes and turning centers. The insert is manufactured from solid carbide and carries a CVD-applied Duratomic multilayer coating of TiCN, Al2O3, and Cr to extend cutting edge life under sustained chip loads. With a 55-degree diamond shape, a 0.5-inch inscribed circle, and a 0.0315-inch corner radius, the DNMG432-MF2 geometry suits general-purpose external and internal turning operations where controlled chip formation is critical. The MF2 chipbreaker is optimized for medium-feed finishing and light roughing passes.

This insert is suited for turning and boring operations on steel and stainless steel workpieces across a range of material grades including P20, P30, and P40. Typical applications include back turning, boring, facing, and general turning on medium to heavy-duty CNC turning centers in job shop and production environments. The negative rake geometry and chamfered-and-honed cutting edge style provide edge strength during interrupted cuts and against hard spots in low-alloy steel stock. Licensed machinists, CNC operators, and toolroom technicians in metalworking and manufacturing facilities are the primary users of this insert.

Key Features

• CVD Duratomic coating: TiCN, Al2O3, and Cr layers for thermal resistance and extended tool life
• 55-degree diamond insert shape with 4 cutting edges for cost-efficient indexing
• MF2 chipbreaker geometry optimized for medium-feed turning on steel and stainless steel
• Negative rake, chamfered and honed cutting edge for edge stability under interrupted or heavy cuts
• Compatible with clamp, pin, and lever-lock insert-holding methods
• Meets both ANSI and ISO insert standards; ISO code DNMG150408-MF2

Compatibility

Designed for use in DNMG-style toolholders that accept clamp, pin, or lever-lock holding methods. Primary workpiece materials are steel (ISO P) and stainless steel (ISO M), with material grades P20, P30, and P40 identified. Confirmed multi-use applications include back turning, boring, facing, and turning.

Installation Notes

Installation should be performed by a qualified CNC operator or toolroom machinist with the machine powered down and the spindle locked before indexing or replacing the insert. Verify that the toolholder pocket is clean and free of chips or debris before seating the insert, and confirm the clamping method — clamp, pin, or lever lock — is properly engaged and torqued per the toolholder manufacturer specifications. Always follow the insert manufacturer recommended cutting data for feed rate and depth of cut; the maximum depth of cut for this insert is 0.5787 inches. Wear appropriate PPE, including cut-resistant gloves, when handling carbide inserts.
