DCMT070204-MM4 WMP20G indexable turning insert, Tiger·tec Gold coating for rostfreier Stahl — Walter Tools

The DCMT070204-MM4 WMP20G is a rhombic 55° indexable turning insert designed for machining rostfreier Stahl under medium to robust cutting conditions.

• Tiger·tec Gold coating for improved tool life
• Optimised MM4 chipbreaker for stable chip control
• 7° relief angle for reliable cutting engagement
• Rhombic 55° form with 0.4 mm corner radius

Reliable performance for rostfreier Stahl turning operations

The Tiger·tec Gold‑based grade WMP20G delivers a balance of wear resistance and edge stability tailored to rostfreier Stahl. Its coating technology reduces adhesion and heat build‑up at the cutting edge, which improves process consistency and reduces the frequency of insert changes. For manufacturing environments where material toughness and built‑up edge are common, this insert offers a measurable improvement in tool life and repeatability, supporting higher uptime and fewer interruptions to the production flow.

Consistent chip control to prevent process interruptions

Equipped with the MM4 chipbreaker and a rhombic 55° geometry, the insert ensures predictable chip formation and evacuation in rotational turning applications. Stable chip control lowers the risk of entanglement and surface damage, enabling uninterrupted cycles on automatic lathes and CNC machines. The controlled chip form also simplifies coolant and tool‑holder selection, so machining strategies remain efficient while protecting workpiece integrity.

Precision geometry that supports accurate finishing and long service intervals

The insert’s 7° relief and 0.4 mm corner radius combine to offer a reliable cutting engagement and defined cutting edge strength. A moderate corner radius helps achieve improved surface finish without sacrificing edge robustness during interrupted cuts. The rhombic 55° shape provides versatile clearance and turning angles for a range of external turning tasks. Together, these geometrical features translate into fewer reworks and consistent part quality across batches.

FAQ

What materials is this insert suitable for?
The DCMT070204‑MM4 WMP20G insert is specified for rostfreier Stahl (material group M) and is formulated to manage the toughness and heat characteristics of these alloys.

How does the Tiger·tec Gold coating benefit production?
Tiger·tec Gold on the WMP20G grade reduces edge adhesion and improves thermal resistance, leading to longer tool life and more consistent machining results in rostfreier Stahl.

Can the MM4 chipbreaker be used on automated lathes?
Yes, the MM4 chipbreaker produces controlled chips suitable for automated lathes and CNC turning centres, helping to reduce stoppages caused by poor chip evacuation.

What cutting characteristics does the rhombic 55° shape offer?
The rhombic 55° geometry provides effective clearance and cutting angles for external turning, enabling versatile tool paths and accessible cutting edges for finishing tasks.

Is the insert compatible with standard insert pockets and toolholders?
The DCMT070204‑MM4 WMP20G fits standard toolholders designed for DCMT‑form inserts; confirm holder compatibility before use to ensure correct clamping and orientation.
