SNMA120412-RK5 WKK10S — Indexable turning insert, Tiger·tec Silver, RK5 chipbreaker (Walter Tools)

SNMA120412-RK5 WKK10S is an indexable turning insert designed for robust machining of cast iron, offering a coated‑carbide grade and a geometry suited to short, controlled chips

• Tiger·tec Silver coating
• Optimised for cast iron (ISO K)
• RK5 chipbreaker for short chips
• 1.2 mm corner radius for stable cutting

Consistent tool life and abrasion resistance for cast iron

The coated‑carbide grade WKK10S, integrated into the Tiger·tec Silver family, is formulated to resist the abrasive wear typical for cast components. This combination produces a dependable cutting edge that maintains performance over extended runs, reducing the frequency of insert changes and unplanned stoppages. The chemistry and coating technology work together to lower flank wear rates and sustain dimensional accuracy across batch production, which translates into measurable productivity gains and fewer tool life surprises.

Geometry that secures cutting stability and repeatable results

The square 90° form and a 1.2 mm corner radius deliver a robust cutting edge that tolerates intermittent and interrupted cuts common in cast‑iron turning. The insert’s 0° (negative) relief geometry increases edge security and reduces the risk of edge chipping under heavy engagement. Together, these attributes support stable cutting forces and predictable surface finish, making the insert suitable for finishing and semi‑finishing passes where consistency and tool life are priorities.

Chip control, handling and process benefits in production

The RK5 chipbreaker is tailored for the brittle, short‑breaking chips of cast iron, promoting reliable evacuation and minimising the risk of chip pack‑up. Using this insert in a matched turning holder helps achieve cleaner swarf flow and reduces manual intervention at the machine. As a square insert, it also offers multiple indexable edges, supporting economical tool use and simplified inventory management. These pragmatic advantages contribute to reduced cycle variability and improved overall equipment effectiveness.

FAQ

Which materials is this insert intended for?
The SNMA120412-RK5 WKK10S insert from Walter Tools is specifically developed for machining cast iron (ISO K), with a carbide grade and coating optimised for abrasive wear and short, brittle chips.

What performance benefits does the Tiger·tec Silver coating provide?
The Tiger·tec Silver coating on the WKK10S grade improves wear resistance and heat management, enabling longer tool life and consistent cutting performance in cast‑iron turning operations.

How does the RK5 chipbreaker influence machining?
The RK5 chipbreaker produces short, controllable chips suited to cast iron, aiding evacuation from the cut and reducing the likelihood of chip entanglement or surface damage.

How many cutting edges are available on a square 90° insert?
A Square 90° insert like this one offers four indexable corners, allowing multiple re‑uses of the cutting geometry before replacement.

What does a 0° (negative) relief mean for stability?
A 0° (negative) relief denotes a reinforced insert geometry that favours edge strength and resistance to chipping, which supports stable cuts under higher radial loads.
