DNMG150608‑RP5 WKK20S indexable turning insert, Tiger‑tec Silver — Walter Tools

DNMG150608‑RP5 WKK20S is a rhombic 55° indexable turning insert engineered for productive turning of cast iron components in industrial machining.

• Tiger‑tec Silver coating for extended tool life
• Grade WKK20S optimised for cast iron machining
• Rhombic 55° form with 0.8 mm nose radius
• Negative 0° rake for stable cutting forces

Consistent performance for cast iron turning

The combination of the WKK20S grade and Tiger‑tec Silver coating addresses the typical challenges of cast iron — high abrasive wear and frequent, short-breaking chips. The insert’s RP5 chipbreaker is designed to condition chips reliably, improving evacuation and reducing the risk of interruptions. The rhombic 55° geometry with a 0.8 mm corner radius delivers a durable edge that balances strength and surface finish, while the negative 0° clearance contributes to stable cutting forces. These technical choices translate into fewer tool changes and more predictable production runs when machining abrasive grey and nodular cast irons.

Improved process reliability and higher productivity

As a coated carbide grade intended for cast iron applications, this insert provides wear resistance that supports longer cutting lengths and steady performance under industrial cycle times. The RP5 chip control works with the insert geometry to moderate chip formation, which often leads to reduced downtime for chip management and quicker cycle completion. Walter Tools’ design focus on robust edge preparation means the insert sustains a repeatable cutting edge under interrupted cuts and heavier depths of cut, delivering measurable gains in operational efficiency for turning centres and lathes handling cast components.

Application guidance and mounting considerations

For clamping and toolholder selection, choose a DNMG‑compatible turning holder that matches the insert’s rhombic 55° seat. The plate thickness designation (06) and form require holders designed for DNMG‑type inserts to ensure correct seating and repeatable indexability. This insert is specifically optimised for cast iron materials (ISO group K); it is not specified for stainless or general steel grades, so selection should follow the workpiece material. Appropriate coolant strategy and feed selection, matched to the chipbreaker and grade, will further extend service life and maintain surface integrity on finished components.

FAQ

What materials is this insert suited for?
The DNMG150608‑RP5 WKK20S insert from Walter Tools is formulated for cast iron machining (ISO group K) and is optimised to handle the abrasive wear characteristics of such materials.

What does the RP5 chipbreaker do?
The RP5 chipbreaker on this Walter Tools insert shapes and controls cast iron chips to promote consistent breakage and evacuation, reducing chip-related interruptions during turning operations.

How does the Tiger‑tec Silver coating benefit machining?
Tiger‑tec Silver coating enhances the wear resistance of the Walter Tools grade WKK20S, extending cutting edge life and supporting stable performance in abrasive cast iron applications.

Is this insert suitable for stainless steel or hardened materials?
This specific grade and geometry are specified for cast iron; it is not indicated for stainless steel or hardened steel applications, so alternative grades should be selected for those materials.

What clamping system is required for this insert?
The DNMG form requires a compatible DNMG turning holder that secures rhombic 55° inserts to ensure correct seating and reliable indexability.
