DNMG110408-FW5 WPP20G – Turning insert, rhombic 55°, Tiger‑tec Gold by Walter Tools

A DNMG110408-FW5 WPP20G turning insert designed for steel machining, combining the Tiger‑tec Gold coating with a FW5 chipbreaker to deliver reliable chip formation and productive metal removal

• Tiger‑tec Gold coated carbide grade WPP20G
• FW5 chipbreaker for reliable chip control
• Rhombic 55° shape with 0.8 mm corner radius
• Optimised for machining steel (ISO group P)

Consistent cutting performance for steel turning

The coated carbide grade WPP20G, part of the Tiger‑tec Gold series, is formulated for efficient machining of steels (ISO group P). The combination of a wear‑resistant coating and a universal substrate delivers improved tool life and predictable wear behaviour, which translates to reduced tool changes and higher uptime. In practice, this means more consistent component tolerances and fewer interrupted runs in batch production. The chemistry and coating structure are tuned to manage the heat and typical chip formation of steel, making this insert a pragmatic choice where process reliability and repeatability are priorities.

Precision geometry that improves component quality

The rhombic 55° insert form and 0.8 mm corner radius are designed to balance edge strength with dimensional accuracy. The 0° (negative) relief angle gives the insert a robust edge for interrupted cuts and heavy engagement, reducing the risk of chipping. This geometry helps maintain a stable cutting line and contributes to consistent surface finish, lowering the need for downstream finishing operations. For operations requiring repeatable parts and tight tolerances, the geometry supports predictable tool behaviour under varying cutting forces.

Stable chip control and higher process security

The FW5 chipbreaker is engineered to shape and evacuate chips reliably when turning steels, minimising the chance of entanglement and cycle interruptions. Effective chip control reduces machine downtime, protects workpiece surfaces and tooling, and simplifies coolant and chip conveyor requirements. Combined with the coated carbide substrate, the chipbreaker promotes uninterrupted machining at production speeds typical for steel turning tasks, delivering measurable productivity gains across mixed production runs.

Practical application guidance and compatibility

This insert is coded as DNMG110408-FW5 WPP20G and is suitable for a wide range of turning operations on unalloyed and alloyed steels. The insert thickness and size code provide mechanical stability in standard toolholders designed for DNMG geometry. Where heavy roughing or interrupted cuts are frequent, the negative relief and robust chipbreaker create resilience; where finer finishes are required, optimised feeds and speeds with moderate depth of cut will exploit the coating’s wear resistance to maintain surface quality. For precise cutting data, match the insert code with the machine capability and material grade, and consult the detailed cutting charts available from the supplier.

FAQ

What materials is this insert suited for? The DNMG110408-FW5 WPP20G insert is optimised for machining steels (ISO group P) and is formulated to handle the heat and chip characteristics typical of unalloyed and alloyed steels.

How does the FW5 chipbreaker affect machining? The FW5 chipbreaker on this Walter Tools insert improves chip control and evacuation during turning, reducing the risk of chip entanglement and helping to maintain stable cutting conditions.

Is the negative relief angle suitable for interrupted cuts? Yes, the 0° negative relief angle gives the insert a stronger cutting edge that is more tolerant of interrupted cuts and heavy engagement in turning applications.

Can this insert be used for finishing operations? With appropriate cutting parameters and feed rates, the WPP20G grade and the insert’s geometry can produce good surface finishes; adjust depth of cut and speed according to the workpiece steel and machine rigidity.

What does the Tiger‑tec Gold series provide? The Tiger‑tec Gold series provides a wear‑resistant coating and substrate combination that aims for extended tool life and consistent performance when machining steels with varied cutting conditions.
