CCMW060204-RK6 WKK20S indexable turning insert, Tiger‑tec Silver, for cast iron — Walter Tools

CCMW060204-RK6 WKK20S is an indexable turning insert designed for productive finishing and medium-duty turning of cast iron, offering controlled chip formation and stable wear resistance.

• Optimised for cast iron machining
• Tiger‑tec Silver coated grade WKK20S
• Rhombic 80° form, 0.4 mm corner radius
• Reliable chip control with RK6 chipbreaker

Consistent cast iron performance for stable production

The combination of a coated carbide grade and a purpose-built RK6 chipbreaker provides measurable advantages when machining cast iron. The coating technology delivers improved resistance to abrasive wear, while the chipbreaker shapes short, breakable chips that reduce re-cutting and improve surface finish. For production environments this means fewer interruptions, more predictable tool life and reduced scrap rates. The result is a cost‑efficient cutting process that supports steady throughput in turning operations.

Precise geometry that improves cutting stability

A rhombic 80° insert shape with a 0.4 mm corner radius and a 7° relief angle gives a balance between cutting strength and accessibility into profiles. The geometry supports steady cutting forces, which reduces vibration and helps maintain dimensional accuracy on turned components. The moderate corner radius is suited to light radii and finishing passes, while the 80° form provides positive engagement for stable chip formation and good toolholder compatibility.

Coating and grade benefits explained for practical use

The Tiger‑tec Silver coating applied to the WKK20S grade is a multi‑layer, wear‑resistant system optimised for abrasive cast iron applications. Coated carbide inserts like this one combine a tough substrate with a protective surface layer that delays flank and crater wear. In practice, this translates to longer intervals between indexings or insert changes and more consistent part quality. The WKK20S grade is tailored to the demands of nodular and grey cast irons, where short, brittle chips and abrasive particles challenge tool life.

Application guidance and integration into workflows

The insert is suitable for medium‑to‑high productivity turning of cast iron components in both single‑piece and batch production. Use the RK6 chipbreaker for general finishing to semi‑roughing operations where controlled, segmented chips are needed to avoid long, stringy chips. Matching the insert with a rigid toolholder and stable clamping reduces the risk of chattering and improves repeatability.

FAQ

What materials is this insert intended for?
The CCMW060204‑RK6 WKK20S insert is designed primarily for cast iron applications; the WKK20S grade and the RK6 chipbreaker are optimised for abrasive, short‑chip behaviour typical of cast iron.

What advantages does the Tiger‑tec Silver coating provide?
Tiger‑tec Silver coating on the WKK20S grade increases wear resistance and thermal stability during extended cutting, which helps to maintain consistent tool life and surface quality on cast iron components.

Which geometry features support finishing operations?
The rhombic 80° form in combination with a 0.4 mm corner radius and a 7° relief angle gives the insert a positive engagement suited to finishing passes while preserving dimensional stability.

Is the RK6 chipbreaker suitable for semi‑roughing?
Yes; the RK6 chipbreaker balances chip control with reliable cutting for finishing and some semi‑roughing conditions, improving safety and reducing chip‑related interruptions.

Can this insert be used in standard toolholders for turning?
The insert’s 80° rhombic form and size code 06 are compatible with standard indexable turning toolholders configured for this insert shape; confirm holder seating and clamping specifications before use.
