DCMT11T308-FK6 WKK10S indexable turning insert, Tiger·tec Silver coating — Walter Tools

The DCMT11T308-FK6 WKK10S is a rhombic 55° indexable turning insert optimised for machining cast iron with a FK6 chipbreaker for stable and predictable chip control

• Tiger·tec Silver coating for extended tool life
• Optimised for cast iron machining (ISO group K)
• Rhombic 55° form with 0.8 mm corner radius
• FK6 chipbreaker for controlled chip formation

Higher productivity on abrasive cast iron

The coated carbide grade WKK10S in the Tiger·tec Silver series is formulated for abrasive cast iron applications, delivering consistent wear resistance and a longer service interval compared with uncoated grades. Because the grade balances hardness and fracture toughness, the cutting edge resists the fast, abrasive wear common when machining grey and nodular cast irons. This results in fewer insert changes and more stable cycle times on batch production runs. The combination of the coated substrate and a chipbreaker designed for cast materials provides reliable chip control that reduces interruptions from built-up edge and broken chips.

Predictable surface finish and dimensional control

The rhombic 55° geometry with a 0.8 mm corner radius and a 7° relief angle creates a versatile cutting profile that supports turning and light finishing passes without compromising strength. The FK6 chipbreaker promotes short, controllable chips which help maintain tool stability and protect the workpiece surface, improving repeatability across parts. Tolerance class M and the standardised insert form make mounting and index changes straightforward, supporting consistent part quality and minimising setup variation in serial production.

Easy integration and reliable process security

This indexable insert is supplied in the established DCMT configuration and fits common toolholders used in turning operations, allowing quick adoption into existing setups. The coated grade and chip control characteristics reduce the need for excessive cutting-fluid adjustments, supporting efficient wet or semi-dry processes. With applicability to ISO group K (cast iron) and a compact plate thickness T3, the insert supports compact clamping arrangements and predictable tool life, helping to lower overall machining costs and downtime.

FAQ

What materials is this insert designed for?
The DCMT11T308-FK6 WKK10S insert (Walter Tools) is specifically designed for machining cast iron and is classified for ISO group K applications.

How does the FK6 chipbreaker affect chip formation?
The FK6 chipbreaker on the DCMT11T308-FK6 WKK10S produces short, controllable chips that reduce entanglement and improve surface integrity during cast iron turning.

What are the key geometry parameters to consider for finishing passes?
Consider the rhombic 55° form and the 0.8 mm corner radius for light finishing; these geometries balance cutting edge strength with the ability to achieve good surface finishes.

Is the coating beneficial for productivity?
Yes, the Tiger·tec Silver coating on the WKK10S grade enhances wear resistance and contributes to longer tool life and more consistent cycle times in abrasive cast iron operations.

Will this insert fit standard DCMT toolholders?
The insert follows the DCMT configuration and is compatible with holders designed for that form; confirm holder compatibility with the toolholder manufacturer and the DCMT11T308-FK6 specification.
