DCMW11T308-RK6 WKK10S turning insert for cast iron, Rhombic 55° by Walter Tools

A DCMW11T308-RK6 WKK10S turning insert engineered for demanding cast-iron operations, combining Tiger·tec Silver coating with an RK6 chipbreaker for controlled chips and stable cutting performance.

• Tiger·tec Silver coated for long tool life
• Optimised for cast iron machining
• Rhombic 55° geometry for versatile turning
• 0.8 mm corner radius for accurate form

Reliable chip control for abrasive cast-iron work

The Tiger·tec Silver grade and the RK6 chipbreaker are matched to the short, often brittle chips typical of cast iron. This combination ensures consistent chip control, reducing interruptions and minimising the risk of built-up edge. Designed as a coated carbide insert, the WKK10S grade offers resistance to abrasive wear, which translates into fewer tool changes and steadier cycle times in production. The rhombic 55° geometry delivers stable cutting forces, helping to maintain dimensional accuracy on turned components.

Durable coating and grade for economical machining

The Tiger·tec Silver coating on the WKK10S grade improves substrate protection against abrasive wear and thermal influence during interrupted cuts. The coated construction supports longer tool life under typical cast-iron conditions, making the insert a cost-effective option for batch and continuous production. With a focus on process economy, the grade balances toughness and hardness to resist flank wear while preserving edge integrity, which reduces unexpected downtime and contributes to predictable tool-change intervals.

Geometry that supports versatility and precision

The rhombic 55° shape with a 0.8 mm corner radius provides a good compromise between strength and finish capability. This radius supports form stability on convex and slight profiling tasks, while the 55° approach angle facilitates both light finishing and more aggressive roughing passes depending on insert orientation. The 0.8 mm corner radius also aids in producing consistent surface texture without excessive cutting forces, which is particularly useful in maintaining part tolerances on cast-iron components.

Practical use and integration into production

The insert’s designation and size align with common toolholder systems for straightforward replacement and upgrade in existing tool chains. Marked by a medium tolerance class and a 7° free cutting edge angle, the insert is suitable where robust chip breaking and repeatable seating are required. For workshop planners and process engineers, this insert represents a pragmatic choice when machining cast iron with repeatable quality demands, combining a familiar geometry with a dedicated chipbreaker and a high-performance coating.

FAQ

What materials is this insert intended for? This turning insert is designed expressly for machining cast iron; the WKK10S grade and chipbreaker are optimised for ISO group K materials.

How does the Tiger·tec Silver coating benefit performance? The Tiger·tec Silver coating increases wear resistance and thermal stability, extending tool life and maintaining cutting-edge integrity in abrasive cast-iron applications.

Which geometry characteristics influence cutting behaviour? The rhombic 55° shape and 0.8 mm corner radius provide a balance of strength and surface finish, while the 7° relief angle helps maintain chip flow and reduce cutting forces.

Is the RK6 chipbreaker suitable for both roughing and finishing? The RK6 chipbreaker is primarily tuned for controlled chip formation in cast iron and performs well across a range of chip loads; selection of cutting parameters will determine suitability for roughing or finishing passes.
