TPGN160304 WKK20S triangular 60° indexable turning insert — Tiger·tec Silver for cast iron by Walter Tools

A TPGN160304 WKK20S triangular turning insert designed for efficient, repeatable machining of cast iron components with optimised wear resistance and chip behaviour

• Tiger·tec Silver coated carbide grade WKK20S
• Optimised for cast iron (ISO group K)
• Triangular 60° form, 16 mm inscribed circle
• Positive rake, 11° free cutting angle

Consistent productivity through optimised grade and coating

The combination of the Tiger·tec Silver coating and the WKK20S grade provides a balance of wear resistance and toughness that suits abrasive, brittle cast‑iron materials. Coated carbide means a hard, wear‑resistant surface layer on a carbide substrate; this reduces flank and crater wear under typical turning conditions and extends the time between index changes. For production environments, this translates into fewer tool changes and steadier cycle times, increasing overall throughput without compromising component quality.

Geometry engineered for controllable chips and surface quality

The triangular 60° form and the 0.4 mm corner radius produce a stable cutting edge geometry for finishing and medium turning operations. The 11° positive rake promotes smoother cutting action and helps to break the short, brittle chips typical of cast iron, reducing the risk of built‑up edge and chatter. A defined corner radius supports consistent surface finish while preserving edge strength; in practice, this means predictable tolerances and fewer rejects when machining batch parts.

Application benefits and simple process integration

This insert is tailored for cast‑iron applications (ISO group K), where abrasive wear and short chips dictate the choice of grade and geometry. The WKK20S sort is a coated carbide designed to handle those conditions with good economy and stable chip formation. Integrating the insert into a turning operation requires only standard indexable‑insert holders compatible with the triangular 60° form; cutting parameters can be adapted from general cast‑iron turning charts and fine‑tuned using short tests to achieve the desired surface finish and tool life.

FAQ

What materials is this insert best suited for?
The insert is optimised for cast iron (ISO group K); the WKK20S coated carbide grade delivers stable wear performance when machining abrasive, brittle cast‑iron alloys.

How does the Tiger·tec Silver coating help in production?
The Tiger·tec Silver coating provides a hard, wear‑resistant surface that extends edge life and improves process stability for continuous turning of cast‑iron components.

Which insert geometry is supplied and what does it mean for holders?
A triangular 60° form with a 16 size and 0.4 mm corner radius is supplied; this fits standard insert holders designed for triangular indexable inserts and supports predictable surface finish and chip control.
