CCMT060204-MK4 WKK10S – Indexable Turning Insert (Rhombic 80°, 7° relief) by Walter Tools

The CCMT060204-MK4 WKK10S is an indexable turning and boring insert engineered for abrasive cast iron machining, offering a combination of wear-resistant coating and a controlled-chip geometry for stable production.

• Tiger·tec Silver coated for long tool life
• Optimised for abrasive cast iron machining
• Rhombic 80° shape for versatile turning
• Chipbreaker MK4 for reliable chip control

Maximise cutting efficiency in cast iron turning

The combination of a coated carbide base and the Tiger·tec Silver technology delivers a robust cutting edge that copes with the high abrasion typical of cast iron. The WKK10S grade is tuned for short, brittle chips and abrasive wear resistance, which leads to longer intervals between insert changes and fewer unplanned stoppages. With a focus on measurable performance, the insert’s geometry reduces flank wear and maintains dimensional stability on repetitive turning cycles, contributing to predictable cycle times and improved component yield. The design supports higher cutting parameters where process stability allows, translating into a tangible increase in productivity for batch and serial production.

Improved surface quality and consistent chip formation

The chipbreaker MK4 and rhombic 80° form provide controlled chip flow and secure edge engagement, resulting in more consistent surface finishes and fewer interruptions from poor chip evacuation. The 7° relief minimises rubbing and heat build-up at the flank, while the corner radius 0.4 mm balances edge strength with the ability to achieve fine surface roughness on interrupted or continuous cuts. This geometry is particularly advantageous where repeatable part quality is required, such as cylinder bores or mating faces, because it reduces the need for secondary finishing and supports stable tool life across a production run.

Practical integration and application guidance

Designed to fit standard CCMT toolholders, the insert’s format and tolerance class M ensure consistent seating and repeatability in conventional turning setups. The grade is explicitly intended for the machining of cast iron, matching the abrasive wear profile and chip behaviour of these materials. For new applications, start with conservative feeds and speeds to determine the optimal combination for a specific cast iron grade; the insert’s stability then allows incremental increases in cutting parameters.

FAQ

What materials is this insert suitable for?
The CCMT060204-MK4 WKK10S insert is optimised for machining cast iron and is designed to handle the abrasive wear and short-chip behaviour typical of those materials.

How does the Tiger·tec Silver coating improve performance?
Tiger·tec Silver enhances wear resistance and thermal stability on the cutting edge; in the WKK10S grade this leads to longer tool life and more consistent machining results on abrasive cast iron.

Which chipbreaker is fitted and what benefit does it offer?
The insert features the MK4 chipbreaker, which ensures controlled chip formation and reliable evacuation, supporting uninterrupted production and improved surface finish.

Is the insert compatible with standard CCMT toolholders?
Yes, the insert follows the CCMT indexable insert standard and is intended for use in standard CCMT-compatible turning and boring toolholders.
