DNGG110402M-MN3 WNN10 turning insert — rhombic 55° form, coated carbide, Walter Tools

The DNGG110402M-MN3 WNN10 is a rhombic 55° turning insert designed for general to semi-finish turning where stable chip formation and repeatable tool life are required, featuring a 0° negative rake and a 0.2 mm corner radius

• Coated carbide grade WNN10
• MN3 chipbreaker for controlled chips
• Rhombic 55° geometry for versatile turning
• 0° negative rake for robust cutting

Optimised productivity through proven grade and chip control

The combination of the WNN10 coated carbide and the MN3 chipbreaker is aimed at improving process stability and reducing secondary operations. The coating on the sintered carbide promotes wear resistance while the chipbreaker geometry channels swarf away from the cutting edge, resulting in fewer interruptions during long turning cycles. For machining tasks that demand repeatable performance, this insert supports a steady cycle time and contributes to predictable tool-change intervals, helping to maintain throughput in batch production or continuous turning processes.

Robust geometry for secure machining and dimensional consistency

A rhombic 55° form together with a 0° negative rake provides a robust cutting corner that tolerates variable workpiece conditions and moderate interruptions. The nominal corner radius of 0.2 mm improves edge strength and reduces the risk of chipping when machining interrupted cuts or tougher material zones. These geometric choices favour dimensional stability and a consistent surface finish, making the insert suitable for routine roughing and semi-finishing operations where tool reliability and part accuracy matter.

Easy specification and integration into tool systems

The insert is offered in the standard ISO designation DNGG110402M-MN3 WNN10 and fits common toolholders sized for 11 mm inserts and 04 thickness. Compatibility with established clamping systems simplifies inventory handling and toolsetting, while the tolerance class G ensures consistent seating and repeatable indexation. Technical documentation and cutting data from Walter Tools assist in selecting appropriate feeds and speeds for the required application, enabling planners and operators to define efficient process parameters with confidence.
