DCMW11T304-RK6 WKK20S — indexable turning insert, Tiger·tec Silver, for cast iron, Walter Tools

DCMW11T304-RK6 WKK20S is an indexable turning insert designed for productive machining of cast iron components, offering a robust grade and a geometry tuned for stable chip control.

• Tiger·tec Silver coating for long life
• Optimised for cast iron machining
• Rhombic 55° form with 0.4 mm corner
• RK6 chipbreaker for stable chip control

Reliable wear resistance for cast iron production

The WKK20S grade, part of the Tiger·tec Silver family, is engineered to resist the abrasive wear typical of cast iron workpieces. The coated carbide formulation delivers improved edge life under interrupted cutting and short, brittle chip formation common to grey and nodular cast irons. This results in fewer tool changes and more predictable tool life, supporting continuous production and reduced downtime. The combination of coating and grade provides a clear advantage where consistent machining of cast-iron components is required.

Geometry that improves stability and surface quality

A rhombic 55° insert form with a 0.4 mm corner radius and a 7° relief angle gives a balanced cutting geometry that supports both light finishing and moderate roughing operations. The RK6 chipbreaker is optimised for producing short, controllable chips, which helps maintain stable cutting forces and consistent surface finish. The insert thickness T3 and tolerance class M contribute to a reliable seating and repeatable indexability in standard toolholders, helping to keep process variance low and component tolerances within specification.

Productivity and process security in everyday use

Designed for productive turning of cast iron, this indexable insert helps increase machining throughput while maintaining quality. The tooling concept reduces the risk of unplanned interruptions thanks to its abrasion resistance and optimised chip control. For operations seeking improved cycle times and fewer tool indexings, the insert delivers measurable process benefits.

FAQ

Which materials is this insert intended for?
The DCMW11T304-RK6 WKK20S insert is optimised for cast iron (ISO group K) and is tuned for the abrasive wear and short, brittle chips typical of these materials.

What benefits does the WKK20S grade provide?
WKK20S, combined with Tiger·tec Silver coating, offers enhanced resistance to abrasive wear and stable edge life in interrupted cutting, which supports longer tool life and consistent machining results.

How does the RK6 chipbreaker influence machining?
The RK6 chipbreaker promotes short, controllable chips, reducing the risk of chip entanglement and supporting steady cutting forces for improved surface finish and process stability.

What are the key geometric specifications to consider?
Important geometry data: rhombic 55° form, 0.4 mm corner radius, 7° relief angle, thickness T3 and insert size 11, all of which affect feed, depth of cut and suitability for finishing or medium roughing.

What does tolerance class M indicate for this insert?
Tolerance class M reflects the dimensional accuracy and interchangeability required for repeatable seating in toolholders, contributing to consistent part quality across indexings.
