DCGT070204-MN2 WNN10 — Indexable turning insert by Walter Tools, rhombic 55° with MN2 chipbreaker

DCGT070204-MN2 WNN10 is an indexable turning insert designed for general turning applications where predictable chip formation and repeatable seating are required

• Coated carbide grade WNN10
• Rhombic 55° insert geometry
• MN2 chipbreaker for controlled chips
• 0.4 mm corner radius and 7° relief

Stable cutting and predictable process results

The coated carbide grade WNN10 provides a balance between wear resistance and toughness, delivering consistent cutting performance across repeated operations. Combined with the MN2 chipbreaker, the insert promotes stable chip formation, reducing interruptions from chip entanglement and easing swarf evacuation. The tolerance class G ensures repeatable seating and interchangeability in suitable toolholders, supporting reliable tool life planning. For production environments where cycle reproducibility is essential, this geometry and cutting concept reduce variability and help maintain throughput.

Geometry and what it means for machining choices

The rhombic 55° shape with a 0.4 mm corner radius and 7° relief gives a compromise between accessibility and edge strength: the acute angle improves reach into profiles, while the modest radius preserves edge stability for light to medium finishing cuts. The nominal size code and plate thickness facilitate straightforward selection of compatible toolholders; however, the specific suitability for a given material batch should be verified against the manufacturer's application matrix. Where a gentler finish or smaller radii are required, the small corner radius here supports finer surface quality without excessive cutting forces.

Practical handling, integration and benefits for workshops

The insert’s chip control and coated substrate simplify daily handling and reduce the need for frequent edge changes, contributing to lower process downtime. The MN2 chipbreaker is optimised for predictable swarf shape, which can reduce machine stoppages and improve operator safety. Inspection of seating and clamping condition is recommended at regular intervals to maintain the tolerance class G performance. For customers seeking precise toolholder pairing or a material-specific recommendation, Metav Werkzeuge can supply the application matrix and advise on optimal cutting parameters to integrate the insert seamlessly into an existing production line.

FAQ

What is the intended use of this insert?
The DCGT070204-MN2 WNN10 indexable turning insert is intended for turning operations where controlled chip formation and reliable seating are priorities; consult the Walter Tools application matrix for specific material guidance.

How does the MN2 chipbreaker affect machining?
The MN2 chipbreaker shapes chips to be more manageable and consistent, reducing the risk of chip-related stoppages and contributing to smoother production cycles with the DCGT070204-MN2 WNN10.

What does the 0.4 mm corner radius mean for surface finish?
A 0.4 mm corner radius balances edge strength and surface quality, enabling finer finishes than larger radii while still providing adequate robustness for routine finishing passes.

Is the insert compatible with standard toolholders?
The insert is manufactured to tolerance class G, which supports repeatable seating; check the toolholder specification against the DCGT070204-MN2 geometry to ensure secure fitment.

Where to find cutting data for this grade?
Cutting data and recommended parameters for the WNN10 grade are provided in the Walter Tools application matrix; Metav Werkzeuge can supply the relevant documentation and parameter advice.
