DCMT11T304-MM4 WMP30G — Indexable turning insert for rostfreier Stahl (Tiger·tec Gold) by Walter Tools

The DCMT11T304-MM4 WMP30G is an indexable turning insert developed for medium to robust machining tasks on rostfreier Stahl, combining a versatile rhombic geometry with a specialised chipbreaker for controlled cutting.

• Tiger·tec Gold coated grade WMP30G
• Designed for rostfreier Stahl (ISO M)
• Rhombic 55° geometry for versatile turning
• 0.4 mm corner radius with MM4 chipbreaker

Consistent cutting performance with Tiger·tec Gold

The coated carbide Tiger·tec Gold grade provides a balanced combination of wear resistance and edge stability, which is particularly beneficial when machining rostfreier Stahl. The specific grade formulation promotes secure chip formation under the heat-generating conditions typical for these alloys, reducing the tendency for built-up edge and preserving surface integrity. In practice this means longer tool life and fewer interruptions for insert changes, helping to keep cycle times predictable and production flow steady.

Controlled chips and improved surface finish

A purpose-designed MM4 chipbreaker together with the rhombic 55° geometry yields reliable chip control and predictable cutting forces. The 0.4 mm corner radius contributes to a strong cutting edge that resists chipping during interrupted cuts while still allowing good surface finish on turned parts. The modest 7° relief angle supports stable contact conditions at the cutting edge, reducing vibration and promoting repeatable results in serial production.

Economical use and process reliability

Tolerance class M and the proven coating technology result in a cost-effective solution for demanding rostfreier Stahl applications. The insert’s T3 thickness and the overall design balance rigidity with accessibility for a range of toolholders. This combination reduces the need for frequent regrinding or replacement, supporting higher throughput and predictable tool consumption—factors that directly lower manufacturing costs over time.

Practical application advice for predictable results

Use this indexable insert for medium to robust finishing and semi‑finishing operations on rostfreier Stahl where stable chip formation is required. The combination of the WMP30G grade and the MM4 chipbreaker is geared towards avoiding built-up edge and maintaining a consistent cut. For matching toolholder and clamping recommendations, consider tool rigidity and mounting overhang to preserve the performance advantages of the insert and to achieve consistent surface quality.

FAQ

What materials is this insert suitable for?
The DCMT11T304-MM4 WMP30G insert by Walter Tools is designed primarily for rostfreier Stahl (ISO M), offering secure chip formation under the higher heat and toughness conditions of these alloys.

How does the MM4 chipbreaker affect machining?
The MM4 chipbreaker on this turning insert stabilises chip flow and reduces the risk of built-up edge, improving surface finish and making the cutting process more predictable for rostfreier Stahl.

Can this insert be used for finishing and semi‑finishing?
Yes, the combination of the WMP30G grade and a 0.4 mm corner radius suits both semi‑finishing and finishing operations where a balance of tool life and surface quality is required.

Is this insert compatible with standard toolholders?
The DCMT11T304-MM4 WMP30G follows common indexable insert geometry (rhombic 55°), making it compatible with appropriate holders designed for this ISO form and size
