DCMT11T308-MK4 WKK10S indexable turning insert — Tiger‑tec Silver for cast iron | Walter Tools

DCMT11T308-MK4 WKK10S is an indexable insert designed for productive cast iron turning applications, combining a Tiger‑tec Silver coating with an MK4 chipbreaker for dependable chip control.

• Tiger‑tec Silver coating for abrasion resistance
• Optimised MK4 chipbreaker for reliable chip control
• Rhombic 55° form with 0.8 mm corner radius
• Suited to cast iron machining (ISO group K)

Material-adapted grade for abrasive cast iron turning

The WKK10S grade, part of the Tiger‑tec Silver series, is engineered specifically for cast iron (ISO group K). Its coated carbide substrate provides enhanced abrasion resistance, which reduces flank wear when machining abrasive grey or ductile castings. This targeted material design translates into longer intervals between insert changes and fewer interruptions in batch production, supporting higher machine uptime and predictable tool-life cycles. The technical balance between hardness and toughness in the grade helps manage the frequently short, breaking chips typical of cast materials.

Geometry that improves chip flow and surface consistency

The insert’s rhombic 55° shape with a 0.8 mm corner radius and 7° clearance combines accessibility for both profiling and light turning with a robust cutting edge for intermittent cuts. The MK4 chipbreaker is optimised for stable chip formation in cast iron, directing chips away from the cutting zone and reducing the risk of built-up edge. This geometry supports repeatable surface finishes and dimensional stability, especially in automated or high-volume turning, where consistent chip evacuation and cutting forces are crucial for process reliability.

Production benefits: predictable throughput and economical use

Configured as an indexable insert in size 11 with T3 thickness, the DCMT11T308-MK4 WKK10S suits shop-floor scenarios that prioritise steady cycle times and low tool-change frequency. The combination of coated carbide and a targeted chipbreaker reduces unplanned downtime and delivers reproducible results across serial workpieces. For operations seeking measurable improvements, this insert contributes to lower unit machining costs through extended tool life and enhanced process stability, while the Walter Tools design supports straightforward insert indexing and minimal set-up variation.
