DNMG150408-RM5 WMP30G — indexable turning insert, Tiger·tec Gold coating, for rostfreier Stahl (Walter Tools)

DNMG150408-RM5 WMP30G is an indexable turning insert designed for turning applications in rostfreier Stahl, combining a rhombic 55° shape with a robust chipbreaker for secure material removal.

• Tiger·tec Gold coated carbide
• Rhombic 55° insert geometry
• 0.8 mm nose radius for stable edges
• Negative 0° rake for secure cutting

Deliver higher productivity when machining rostfreier Stahl

The combination of the Tiger·tec Gold coating and the WMP30G grade is engineered to counter the typical challenges of machining rostfreier Stahl: high workpiece toughness, built-up edge tendency and heat generation. The coated carbide substrate provides improved wear resistance and thermal stability, while the RM5 chipbreaker promotes manageable chips and repeatable cutting conditions. As a result, cycle times can be optimised and downtime for edge repairs reduced without compromising finished-part integrity.

Stable chip control and improved surface finish

The RM5 chipbreaker is shaped to produce short, even chips when used in combination with the rhombic 55° geometry, which moderates the engagement angle and aids stability during interrupted cuts. The negative 0° rake angle increases edge strength to resist chipping under tougher cutting regimes, so the operator obtains a more consistent surface quality. For less experienced users, coated carbide means a predictable wear pattern and simpler process parameter choice, reducing trial-and-error set‑up time on the shop floor.

Robust edge life and repeatable results

The Tiger·tec Gold technology contributes to a durable cutting edge and controlled flank wear; this improves reproducibility across multiple insert changes and supports stable tool life in serial production. The insert’s tolerance class M and robust execution ensure that the cutting edge remains reliable under medium to heavy conditions typical for rostfreier Stahl work. Longer intervals between indexings and fewer scrap parts support the rational case for productivity gains and lower effective machining costs.

Practical fitment and machining notes for production use

The insert’s rhombic 55° form, size 15 and thickness 04, together with the 0.8 mm nose radius, offer a balanced compromise between edge strength and ability to deliver a fine surface finish. The designation DNMG150408 indicates the standard geometry for commonly used tool holders; the RM5 chipbreaker and WMP30G grade are matched primarily for ISO group M applications. When integrating this insert into a turning cell, select compatible clamping systems and verify cutting data charts for rostfreier Stahl to achieve the best combination of feed and speed.

FAQ

What materials is this insert best suited for? The DNMG150408‑RM5 WMP30G insert is optimised for rostfreier Stahl (ISO group M), where the Tiger·tec Gold grade and RM5 chipbreaker help to manage toughness and heat during turning.

How does the RM5 chipbreaker affect machining? The RM5 chipbreaker on this Walter Tools insert promotes controlled, short chips and helps to reduce the risk of built‑up edge, improving process stability and surface finish in rostfreier Stahl turning.

Is the negative 0° rake suitable for interrupted cuts? Yes, the negative 0° rake angle increases edge strength, making the DNMG150408‑RM5 WMP30G a good option for applications with interrupted cuts or heavier radial engagement.

What surface quality can be expected with a 0.8 mm nose radius? A 0.8 mm nose radius provides a compromise between a strong cutting edge and the ability to produce a consistent surface finish; it is commonly chosen where both durability and finish matter.

Which series and coating technology does this insert use? This insert belongs to the Tiger-tec Gold series and uses the WMP30G coated carbide grade, designed for reliable performance when machining rostfreier Stahl.
