CCMT09T308‑MK4 WKK10S — Rhombic 80° turning and boring insert, Tiger·tec Silver, Walter Tools

A CCMT09T308‑MK4 WKK10S coated carbide insert designed for efficient machining of cast iron in turning and bore‑work, offering controlled chip formation and extended tool life.

• Tiger·tec Silver coating for wear resistance
• Optimised for cast‑iron machining
• Rhombic 80° form with 0.8 mm nose radius
• 7° clearance and MK4 chipbreaker design

Increased productivity through a wear‑resistant coating

The combination of the Tiger·tec Silver coating and the WKK10S grade provides pronounced resistance to abrasive wear typical of grey and nodular cast irons. This coated carbide technology reduces flank wear and extends service intervals, which in turn lowers tooling costs and minimises machine downtime. The result is a reliable cutting edge that keeps productivity high during repetitive turning operations while maintaining consistent dimensional accuracy.

Better surface finish and chip control from optimised geometry

The Rhombic 80° geometry paired with a 0.8 mm nose radius creates a favourable balance between cutting strength and accessibility, making the insert suitable for a wide range of turning and finishing passes. The MK4 chipbreaker is engineered to handle the short, brittle chips produced by cast iron, improving evacuation and reducing risk of built‑up edge. A 7° clearance angle helps prevent rubbing and supports smooth, repeatable surface finishes on components.

Practical versatility for workshop and production environments

Designed as a multi‑purpose turning and boring insert, the CCMT form supports both roughing and finishing steps when the process parameters are set accordingly. The insert’s specifications favour cast‑iron workpieces (ISO group K), offering predictable tool life and stable cutting behaviour. For operations seeking an economical, straightforward solution for series turning of cast‑iron parts, this insert provides a sound balance of performance and simplicity.

FAQ

Which materials is this insert best suited for?
The CCMT09T308‑MK4 WKK10S is optimised for cast iron (ISO group K) and is tuned to the abrasive wear and short‑breaking chips typical for these materials.

What benefits does the Tiger·tec Silver coating provide?
Tiger·tec Silver enhances wear resistance and cutting edge durability, improving tool life and consistency in machining cycles when using the WKK10S grade.

Can the insert be used for both roughing and finishing?
Yes, with appropriate parameter selection the rhombic 80° geometry and the MK4 chipbreaker allow both productive roughing and fine finishing steps.

How does the MK4 chipbreaker affect chip formation?
The MK4 chipbreaker promotes controlled, short chips for cast‑iron machining, aiding safe evacuation and reducing the likelihood of chip entanglement.

Is this insert compatible with standard CCMT toolholders?
The insert follows the CCMT designation and fits compatible toolholders designed for CCMT inserts; ensure correct clamping and seat condition for secure use.
