DCMT11T308-MW4 WKK10S indexable turning insert – Tiger·tec Silver, for cast iron (Walter Tools)

The DCMT11T308-MW4 WKK10S is an indexable turning insert engineered for reliable finishing and medium-duty roughing of cast iron, combining a wear-resistant coating with a chipformer optimised for short, breaking chips.

• Tiger·tec Silver coating for wear resistance
• Optimised for cast iron machining
• Rhombus 55° shape with 7° relief
• 0.8 mm corner radius for stable cutting

Longer tool life through advanced coating and grade

The combination of the Tiger·tec Silver coating and the WKK10S grade yields a consistently durable cutting edge under the abrasive conditions typical of cast iron machining. The layered coating reduces flank wear and heat build-up, which extends usable tool life and reduces frequency of index changes. For production environments this means fewer interruptions and a more predictable maintenance rhythm. The insert is a coated carbide design that balances toughness and abrasion resistance, giving a measurable benefit in both economy and uptime.

Predictable chip formation and improved process security

Equipped with the MW4 chipbreaker and tailored to material group K (cast iron), this insert produces short, controllable chips that are easy to evacuate. Stable chip formation is crucial for unattended operations and for avoiding damage to the workpiece and toolholder. The chipbreaker geometry is specifically adapted to the fragmenting behaviour of cast iron, limiting entanglement and supporting consistent surface quality. As a result, the insert contributes directly to higher process reliability and a lower scrap rate.

Geometry tuned for dimensional stability and surface quality

The Rhombus 55° shape and 7° relief angle provide a versatile cutting geometry that suits a range of turning strategies, including profiling and light turning. The 0.8 mm corner radius offers a good compromise between edge strength and surface finish: it reinforces the cutting edge under intermittent cuts while still enabling fine finishes when required. The medium tolerance class M supports repeatable seating in standard toolholders, helping to maintain consistent part accuracy across index changes.

Easy integration into machining workflows

With its standard DCMT designation and common insert size, the component integrates smoothly into existing toolholders and production setups without the need for bespoke fixtures. The insert’s characteristics — coating, chipbreaker and geometry — make it suitable for both serial production and single-part machining where cast iron components demand stable, repeatable results. Combined with Walter Tools’ known consistency in manufacturing, the insert supports efficient tool management and predictable process planning.

FAQ

What materials is this insert suited for?
The DCMT11T308-MW4 WKK10S is designed primarily for cast iron machining (material group K), where its coating and chipbreaker deliver stable performance.

How does the Tiger·tec Silver coating help in production?
The Tiger·tec Silver coating on the WKK10S grade reduces flank wear and heat, improving tool life and contributing to more consistent machining cycles with fewer index changes.

What advantage does the MW4 chipbreaker provide?
The MW4 chipbreaker is shaped for short, breaking chips typical of cast iron workpieces, helping to avoid chip entanglement and reducing the risk of surface damage.

Is the insert compatible with standard toolholders?
Yes — the DCMT11T308-MW4 format and Rhombus 55° geometry are standard dimensions that fit common toolholders used for turning inserts of this series.

How does the 0.8 mm corner radius influence results?
A 0.8 mm corner radius improves edge strength under interrupted cuts while still enabling good surface finish, offering a compromise between robustness and finish quality.
