DNGG150404M-MN3 WNN10 turning indexable insert by Walter Tools — rhombic 55° geometry, MN3 chipbreaker

A DNGG150404M-MN3 WNN10 is a rhombic 55° turning insert designed for general turning operations where robust cutting, predictable chip control and repeatable performance are required.

• Rhombic 55° geometry for versatile turning
• Coated carbide grade WNN10 for broad use
• Zero-degree negative rake for robust cutting
• MN3 chipbreaker with 0.4 mm corner radius

Durable geometry that increases process stability

The rhombic 55° geometry combined with a 0° (negative) rake delivers a stable cutting angle that reduces insert breakouts and supports dependable tool life under varying cutting conditions. This geometry provides a compromise between reach and strength, permitting secure clamping and reliable entry into the cut; the result is improved process stability and fewer interruptions on production runs. For workshops needing consistent productivity, the insert’s form reduces the risk of chatter and helps maintain surface finish over longer cycles.

Coated carbide grade built for broad applications

The WNN10 designation signifies a coated carbide grade tailored for general-purpose turning. The coating enhances wear resistance and contributes to sustained cutting performance on a range of workpiece materials, while the substrate supports edge stability. Material suitability should be confirmed against the manufacturer’s product matrix before use; this ensures the chosen grade matches the specific steels or alloys in a given application. Proper selection leads to lower tooling costs per part through longer intervals between indexings.

Controlled chip formation for safer machining

The MN3 chipbreaker has been developed to shape and evacuate chips effectively in routine turning tasks, reducing the risk of entanglement and improving surface integrity. Together with a 0.4 mm corner radius, the chip control strategy softens the cutting impact at the edge, which can reduce micro-chipping and contribute to a steadier surface quality. This configuration is particularly beneficial in serial production where repeatability and minimal rework are priorities.

Practical fit, handling and insertion benefits

The insert follows standard dimensions with a nominal size 15 and thickness code 04, enabling compatibility with common tool holders for rhombic 55° inserts. The naming convention and ISO-style designation simplify procurement and inventory management, while the robust format supports straightforward indexing for multi-edge use. For users planning toolholder selection or inventory stocking, the clear ISO-style label and chipbreaker type ease identification and reduce the time spent matching inserts to holders.

FAQ

What cutting geometry does this insert use?
The insert features a rhombic 55° geometry with a 0° (negative) rake, offering a robust angle for general turning operations and reliable edge engagement.

Which chipbreaker and corner radius are specified?
This indexable insert uses the MN3 chipbreaker and a 0.4 mm corner radius, optimised for controlled chip formation and improved edge stability during routine turning.

Is the WNN10 grade suitable for all materials?
The WNN10 coated carbide grade is intended for broad use, but material suitability should be checked against the manufacturer’s product matrix to ensure optimal performance on the intended workpiece materials.

How does the negative rake affect cutting performance?
A negative rake increases edge strength and resistance to mechanical stress, making the insert suitable for heavier cuts and interrupted cuts where robustness is required.

How is the insert identified for procurement and inventory?
Identification follows the ISO-style designation DNGG150404M-MN3 WNN10, which aligns with common ordering and stocking practices for turning inserts.
