DCMT070208-MM4 WMP20G indexable turning insert — for rostfreier Stahl, Walter Tools

The DCMT070208-MM4 WMP20G is an indexable turning insert engineered for medium to robust machining of rostfreier Stahl, offering a balance of edge stability and consistent chip formation.

• Tiger‑tec Gold coated grade WMP20G
• Optimised for stainless steels (ISO M)
• MM4 chipbreaker for reliable chip control
• Rhombic 55° shape with 0.8 mm corner radius
• 7° clearance angle, 2 mm plate thickness

Reliable performance for rostfreier Stahl under demanding conditions

The combination of the Tiger‑tec Gold coating and the WMP20G grade provides a material system tailored for rostfreier Stahl, a group known for toughness and tendency to produce built-up edge. The specialised coating reduces friction and improves thermal resistance, which leads to a stable cutting edge and extended tool life. In practice, this means fewer insert changes, more consistent part quality and improved productivity in turning operations where heat and adhesion present challenges. The result is a predictable process with reduced downtime and improved cost-efficiency per component.

Geometry and chip control that support consistent surface quality

Designed with a rhombic 55° outline and an MM4 chipbreaker, the insert delivers concise chip segmentation and evacuation. The 0.8 mm corner radius helps to maintain edge strength while providing the surface finish expected in precision turning tasks. The MM4 chipbreaker aids in controlling the chip flow for a wide range of feeds and depths of cut, reducing the likelihood of surface defects caused by erratic chips. Together, these features improve part quality and lower the risk of secondary operations to correct surface issues.

Precision features that increase process security and throughput

A clearance angle of 7° and a plate thickness of 2 mm ensure the insert mounts securely while offering the rigidity required for robust cutting conditions. The coated carbide substrate is optimised to withstand temperature peaks typical for rostfreier Stahl machining, supporting repeatable performance across batches. For operations prioritising throughput, the insert’s balanced design contributes to consistent cycle times and reliable tool life, which in turn supports predictable production scheduling and cost calculations.

FAQ

What materials is this insert suitable for?
The DCMT070208-MM4 WMP20G is formulated for rostfreier Stahl and classified for ISO M applications, making it suitable for stainless steel turning where adhesion and heat are critical factors.

What does MM4 chipbreaker provide in practice?
The MM4 chipbreaker ensures controlled chip segmentation and evacuation, improving surface finish consistency and reducing the risk of chip-related interruptions during turning operations.

How does the Tiger‑tec Gold coating benefit machining?
Tiger‑tec Gold enhances thermal resistance and reduces friction at the cutting zone, which supports a stable cutting edge and longer life when machining rostfreier Stahl.

Can this insert handle heavy cuts or interrupted cuts?
The insert’s 0.8 mm corner radius and robust coated carbide grade deliver edge strength suitable for medium to robust cutting conditions; however, specific process parameters should be validated for heavy or highly interrupted cuts.

Which geometry features influence surface quality?
The rhombic 55° shape combined with the 0.8 mm corner radius and MM4 chipbreaker contribute directly to chip control and the resulting surface integrity on turned parts.
