DNMG110408-RP5 WPP20G turning insert for steel by Walter Tools — Tiger‑tec Gold, RP5 chipbreaker

The DNMG110408-RP5 WPP20G is a rhombic 55° turning insert designed for medium to general steel machining where consistent chip control and long tool life are required

• Tiger‑tec Gold coating for extended life
• Optimised RP5 chipbreaker for steel machining
• Rhombic 55° geometry for versatile turning
• 0.8 mm corner radius for robust edge strength

Reliable cutting performance for steels and stable machining results

The insert combines the WPP20G coated carbide grade with the Tiger‑tec Gold coating to deliver a balance of wear resistance and toughness. This combination is optimised for ISO P materials, meaning the grade and coating are tuned to handle the typical heat generation and chip formation encountered when machining unalloyed and alloyed steel. The RP5 chipbreaker ensures predictable chip segmentation, which reduces the risk of long, stringy chips and contributes to a safer, more efficient machining process. In practical terms, the result is fewer interruptions, lower rework rates and improved cycle-time consistency.

Geometry and edge design that support process security and surface quality

Featuring a rhombic 55° shape and a corner radius of 0.8 mm, this insert offers a compromise between edge strength and finishing capability. The negative 0° rake (negative cutting angle) increases edge stability for heavier cuts and interrupted turning, while the insert’s 11 mm size and 4 mm thickness provide mechanical robustness in demanding setups. For operators and process planners, this means the insert is suitable for a wide range of turning tasks—from roughing passes that demand durability to finishing operations that still require a controlled surface outcome. The geometry reduces the tendency for vibration at moderate cutting parameters, supporting a stable machining window.

Practical advantages in workshop use and tool management

The insert’s ISO designation and proven chipbreaker design simplify tool selection and process documentation in an industrial environment. As a standard DNMG insert, it integrates with widely used clamping systems and toolholders, easing inventory management and changeover. The WPP20G grade, part of the Tiger‑tec Gold family, is manufactured for repeatable performance: predictable wear patterns facilitate tool-life monitoring and replacement scheduling. From a cost-efficiency perspective, the combination of coating and grade reduces the frequency of indexing and regrinding, improving overall uptime and lowering effective tooling cost per component.

FAQ

What materials is this insert intended for?
The DNMG110408-RP5 WPP20G insert is specified for ISO P applications and is intended primarily for machining unalloyed and alloyed steel.

How does the RP5 chipbreaker affect machining?
The RP5 chipbreaker on the WPP20G grade promotes controlled chip segmentation during turning of steel, improving chip evacuation and reducing the risk of entangling or long continuous chips.

Is the insert suitable for interrupted cuts?
Yes, the negative 0° rake and 0.8 mm corner radius provide enhanced edge strength, making the insert appropriate for interrupted turning and heavier engagement conditions.

Can the insert be used for finishing operations?
The rhombic 55° geometry and moderate corner radius allow for finishing passes with controlled surface quality, while still offering the robustness needed for mixed operation sequences.

Which toolholders are compatible with this insert form?
The DNMG form is a standard geometry that fits common DNMG-indexable toolholders; check holder compatibility for size and clamping style before use.
