DCGT11T304-MM4 WSM20S turning insert — Walter Tools, Tiger·tec Silver, 7° relief, 0.4 mm radius

A DCGT11T304-MM4 WSM20S turning insert designed for medium to heavy duty turning of stainless steel and heat-resistant superalloys, combining a rhombic 55° form with Tiger·tec Silver coating for enhanced thermal resistance and edge stability.

• Tiger·tec Silver coating for thermal resistance
• Suited for stainless steel and superalloys
• Rhombic 55° geometry for versatile turning
• 0.4 mm corner radius for refined finish

Stable edge control for demanding materials

The combination of a coated carbide grade and the Tiger·tec Silver technology provides a durable cutting edge that reduces edge wear during prolonged engagement with demanding materials. For components made of stainless steel or nickel-based alloys the insert’s composition supports secure chip formation and helps prevent built-up edge, which in turn maintains dimensional stability and surface quality. The MM4 chipformer is tailored to break and evacuate chips reliably under variable depths of cut, reducing the risk of re-cutting and improving process repeatability.

Geometry and finish: consistent surfaces with minimal rework

The rhombic 55° form paired with a 0.4 mm corner radius offers a balance between strength and finish quality. This geometry allows reliable plunge and profiling operations while the modest radius aids in producing a uniform surface without overstressing the cutting edge. The insert’s 7° relief angle reduces rubbing on the flank, lowering heat generation and supporting a better surface condition on the workpiece. As a result, secondary finishing operations can be minimised, supporting shorter cycle times and higher throughput.

Application guidance and process reliability

When machining heat-resistant alloys and stainless steel, the insert’s coated substrate and robust edge control improve process security under thermally challenging conditions. The DCGT11T304-MM4 WSM20S insert is suitable for toolholders that accept DCGT-style cartridges and performs well in interrupted cuts or components with variable cross-sections. Selecting a stable holder and appropriate clamping, together with a coolant strategy adapted to the workpiece and machine, will amplify the benefits of the insert’s Tiger·tec Silver surface and ensure consistent tool life and part quality.

FAQ

What materials is this insert designed for?
The DCGT11T304-MM4 WSM20S insert from Walter Tools is formulated for machining stainless steel and heat-resistant superalloys, offering improved chip control and edge stability for those material groups.

How does the Tiger·tec Silver coating benefit the cutting process?
Tiger·tec Silver on the DCGT11T304-MM4 WSM20S increases thermal resistance and reduces abrasive wear, which extends usable edge life and maintains consistent cutting performance in thermally demanding applications.

When is the 0.4 mm corner radius recommended?
A 0.4 mm corner radius on this turning insert supports a fine surface finish while retaining sufficient edge strength for general turning and light profiling; it is particularly useful where reduced post-process finishing is desired.

Which operations suit the rhombic 55° geometry and MM4 chipformer?
The rhombic 55° form combined with the MM4 chipbreaker makes the insert versatile for facing, longitudinal turning and medium-depth profile work, with reliable chip breakage in variable cutting conditions.
