CNMG160616-MK5 WKK10S Drehwendeschneidplatte – Tiger·tec Silver for cast iron | Walter Tools

The CNMG160616-MK5 WKK10S is a rhombic 80° turning insert designed for efficient machining of cast iron, combining a coated carbide grade with a dedicated chipbreaker for consistent performance.

• Tiger·tec Silver coating for wear resistance
• Designed for cast iron (K) materials
• Rhombic 80° geometry, 1.6 mm corner radius
• Negative rake 0° for stable cutting

Consistent wear resistance for productive cast-iron turning

The WKK10S grade, applied within Walter Tools' Tiger·tec Silver series, is a coated carbide solution formulated for abrasive cast-iron applications. Because the grade is tuned to the short, brittle chips typical of cast materials, the insert provides improved wear resistance and extended edge life compared with uncoated alternatives. The result is fewer tool changes and higher machine uptime, which directly supports process efficiency and predictable production cycles.

Geometry tuned for strength and reliable surface quality

The CNMG rhombic shape with 80° lead angle and a 1.6 mm corner radius balances cutting-edge strength and achievable surface finish. The negative 0° rake increases edge robustness under interrupted cuts and heavy engagement, while the MK5 chipbreaker promotes controlled chip formation. This geometry and edge preparation allow stable cutting forces and reduced vibration, enhancing dimensional repeatability and component quality even in challenging cast-iron workpieces.

Practical application advice for stable machining results

As an indexable insert for turning, the plate is intended for a range of turning tasks on cast iron according to ISO group K. The MK5 chipbreaker supports reliable chip control during both roughing and finishing passes, lowering the risk of built-up edge and workpiece damage. For best results in production environments, pair the insert with a rigid tool holder and a stable clamping setup to exploit the grade’s process security and achieve consistent cycle times.

FAQ

What materials is this insert suitable for?
The CNMG160616-MK5 WKK10S from Walter Tools is designed primarily for cast iron machining (ISO group K) and is optimised for the abrasive, short-chipping behaviour typical of these materials.

What does the MK5 chipbreaker do?
The MK5 chipbreaker on this insert controls chip formation in cast-iron turning, producing short, manageable chips and reducing the risk of chip entanglement and built-up edge.

How does the 1.6 mm corner radius affect performance?
A 1.6 mm corner radius offers a compromise between edge strength and surface finish; it increases resistance to edge wear and is suitable for stable cutting conditions where a secure edge is required.

Is the Tiger·tec Silver grade a coating or substrate?
Tiger·tec Silver refers to the coating technology applied to the WKK10S coated carbide grade, delivering improved wear resistance and longer tool life in abrasive cast-iron applications.

Can this insert be used for finishing as well as roughing?
Yes, the insert’s geometry and MK5 chip control make it suitable for both roughing and certain finishing passes on cast iron when used with appropriate cutting parameters and a rigid setup.
