VBMT160408-MK4 WKK10S turning insert — Tiger·tec Silver for cast iron, Walter Tools

A VBMT160408-MK4 WKK10S is a rhombic 35° coated turning insert from Walter Tools, optimised for efficient and repeatable machining of cast iron components.

• Tiger·tec Silver coating for wear resistance
• Optimised for cast iron (K) machining
• MK4 chipbreaker for controlled short chips
• 0.8 mm nose radius, 5° clearance

Consistent chip control for stable productivity

The combination of the MK4 chipbreaker and the WKK10S grade is engineered to manage the short, brittle chips typical of cast iron. This results in reduced risk of chip-related interruptions and clearer swarf evacuation, which in turn supports longer uninterrupted cutting cycles. Such predictable chip formation contributes directly to higher machine uptime and more economical component throughput, making the solution well suited to repeat production and mixed-batch work where process reliability is key.

Coating and grade that extend tool life

The WKK10S is a coated carbide grade within the Tiger·tec Silver family, designed specifically for abrasive wear conditions found in cast iron. The coating improves edge stability and reduces flank wear, which preserves dimensional accuracy over longer tool lives. For operations where changing inserts frequently disrupts flow, this performance translates into lower tool consumption and improved part quality. The technical combination supports consistent surface finish without sacrificing machining speed.

Geometry designed for simple setup and good finishes

The Rhombus 35° form with a 0.8 mm nose radius and 5° clearance offers a balance between cutting strength and accessible cutting geometry. The relatively large nose radius helps achieve stable contact for improved surface finish, while the 35° lead angle reduces cutting forces on the workpiece. These geometric choices make tool selection and insert indexing straightforward, enabling quick integration into existing toolholders and predictable results when switching between similar cast-iron components.

FAQ

Which materials is this insert intended for?
The VBMT160408-MK4 WKK10S insert is tailored for cast iron (material group K) and its grade and geometry address the abrasive wear and short-chip behaviour typical of these alloys.

What advantage does the MK4 chipbreaker provide?
The MK4 chipbreaker on this Walter Tools insert enables controlled short chips during cast-iron turning, improving chip evacuation and reducing the risk of entanglement or surface damage.

How does the Tiger·tec Silver coating affect performance?
The Tiger·tec Silver coating on the WKK10S grade enhances edge stability and wear resistance, which supports longer tool life and consistent surface quality under abrasive conditions.

Will this insert give a good surface finish with a 0.8 mm nose radius?
Yes; the 0.8 mm nose radius offers a compromise between robustness and surface finish, delivering stable cutting contact that often results in improved surface quality compared with smaller radii in heavy interrupted cuts.

Is this insert suitable for stainless steel or aluminium?
This specific grade and geometry are specified for cast iron; there is no indication that the VBMT160408-MK4 WKK10S is optimised for stainless steel or aluminium applications.
