DCMT11T308‑MW4 WKK20S – Indexable turning insert, Tiger‑tec Silver grade for cast iron machining | Walter Tools

A DCMT11T308‑MW4 WKK20S indexable turning insert engineered for productive finishing and reliable chip control in cast iron components

• Tiger‑tec Silver coating for wear resistance
• MW4 chipbreaker for controlled chips
• Optimised for cast iron (ISO K)
• Rhombus 55° form with 7° clearance

Higher productivity through advanced coating and grade

The combination of the Tiger‑tec Silver system with the WKK20S grade delivers a measurable improvement in tool life and process reliability. The insert’s coated carbide substrate provides resistance to the abrasive wear typical of cast iron machining, reducing tool changes and downtime. For production environments where cycle time and tool consumption are key performance indicators, this geometry helps maintain consistent metal removal rates and surface finish quality.

Stable chip control that secures machining processes

Controlled chip formation is a decisive factor for uninterrupted turning operations. The MW4 chipbreaker on this insert promotes short, easily evacuated chips when cutting cast iron, lowering the risk of chip entanglement and tool damage. As a consequence, machine uptime increases and secondary operations for chip handling are minimised, which supports predictable cycle times and improved overall equipment effectiveness (OEE).

Precision geometry for consistent surface quality

The Rhombus 55° platform combined with a 7° clearance and a 0.8 mm corner radius ensures a reliable cutting edge contact and repeatable dimensional results. This geometry, together with tolerance class M, offers a balance between robustness and the ability to produce fine surface finishes on turned faces. The insert’s size 11 designation and T3 thickness contribute to secure clamping and stable cutting conditions under a range of feed and depth settings.

Application focus: optimised for ISO K materials

Designed specifically for ISO K applications, the insert addresses the typical challenges of cast iron: abrasive constituents and short, brittle chips. The WKK20S grade is tuned for these conditions to provide consistent performance across a broad set of cast iron types. For shops aiming to standardise on a versatile indexable solution, this insert supports both productive roughing and reliable finishing passes when parameters are set according to workpiece grade and machine capability.

FAQ

What materials is this insert suited for?
The DCMT11T308‑MW4 WKK20S is specifically optimised for cast iron (ISO K); the WKK20S grade and Tiger‑tec Silver coating address abrasive wear and short-chip formation typical of these materials.

How does the MW4 chipbreaker improve machining?
The MW4 chipbreaker produces short, controlled chips which reduce entanglement and help maintain continuous cutting conditions, improving process reliability with the Walter Tools insert.

What does the Rhombus 55° form mean for cutting?
A Rhombus 55° profile gives versatility in turning operations by combining accessibility for external contours with a stable cutting edge geometry that supports repeatable surface quality.

Can this insert be used for finishing and roughing?
Yes, the combination of WKK20S grade and geometry provides a balance suited to both productive roughing and consistent finishing operations on cast iron components.

What are the key geometry values to consider when programming?
Important values include the 0.8 mm corner radius, 7° clearance, and the size 11/T3 designation; these parameters influence feed, depth of cut and expected surface finish.
