DNGG110404M-MN3 WNN10 — Turning indexable insert by Walter Tools, Rhombus 55° & MN3

The DNGG110404M-MN3 WNN10 is a rhombic turning insert intended for precision lathe operations where predictable chip formation and robust edge behaviour are required

• Rhombic 55° geometry for stable cutting
• 0.4 mm corner radius for consistent edge life
• Coated carbide grade WNN10 for wear resistance
• MN3 chipbreaker for controlled chip formation

Predictable geometry for consistent component finish

The rhombic 55° geometry provides a reliable cutting angle that supports stable engagement and predictable tool forces. Combined with a 0.4 mm corner radius, the geometry helps to distribute cutting stresses and reduce the risk of premature edge chipping, which in turn contributes to a consistent surface finish on the turned workpiece. The negative free angle of 0° (negative) increases edge strength for heavier cuts; this arrangement is particularly useful when robustness and repeatability are priorities in serial production.

Controlled chip formation and wear performance

Equipped with the MN3 chipbreaker, the insert promotes reliable chip control across a range of turning conditions, reducing the incidence of long, entangling chips and improving process safety. The cutting material is a coated carbide in grade WNN10, which provides wear resistance and thermal stability during continuous cutting. Note that the grade’s suitability for specific workpiece materials should be verified against the manufacturer’s product matrix to ensure optimal performance and tool life.

Practical benefits for workshop integration

The DNGG110404M-MN3 WNN10 is supplied in a standard insert designation that simplifies toolholder selection and stocking. With a size code of 11 and thickness code 04, it fits conventional clamping systems used in turning operations, while the tolerance class G assures consistent fit and repeatability. These attributes reduce setup time and support steady production throughput. For applications requiring material-specific advice, the product matrix or Metav Werkzeuge’s technical consultants can clarify optimal cutting parameters and grade selection.

FAQ

What is the main advantage of the MN3 chipbreaker?
The MN3 chipbreaker on the DNGG110404M-MN3 WNN10 produces short, controllable chips, improving process safety and reducing the need for chip handling during turning operations.

Is the WNN10 grade suitable for all materials?
WNN10 is a coated carbide grade; its application range should be confirmed via the manufacturer’s product matrix to ensure compatibility with the intended workpiece material and cutting conditions.

How does the 0.4 mm corner radius affect performance?
A corner radius of 0.4 mm increases edge strength and contributes to a consistent surface finish; it is well suited for general turning where a balance between strength and form accuracy is required.

Can this insert be used in standard toolholders?
Yes, the DNGG110404M-MN3 WNN10 follows a standard insert designation and is compatible with common turning toolholders designed for rhombic 55° inserts.
