SNMA120416-RK5 WKK10S – Turning insert, Tiger‑tec Silver, RK5 chipbreaker (Walter Tools)

The SNMA120416-RK5 WKK10S is a square turning insert designed for high-performance finishing and medium-duty roughing of cast iron components

*Tiger‑tec Silver coating
*Optimised for cast iron (ISO K)
*RK5 chipbreaker for consistent chips
*Square 90° geometry, 1.6 mm corner radius

Consistent machining performance for cast iron production

The SNMA120416-RK5 WKK10S insert combines the Tiger‑tec Silver coating with the WKK10S carbide grade to address the abrasive wear typical of cast iron machining. The coated cemented-carbide substrate increases resistance to abrasive degradation and thermal damage, which translates into longer cutting edge life and fewer tool changes. For production environments where uptime and predictable tool life matter most, this combination supports steady cycle times and reduced process variance.

Reliable chip control and dimensional stability

The dedicated RK5 chipbreaker is engineered to produce short, repeatable chips when cutting grey and nodular cast irons, reducing the risk of entanglement and improving surface consistency. The square 90° geometry with a 1.6 mm corner radius offers robust edge support for shoulder cuts and facing operations, while the 0° (negative) relief configuration provides stable cutting behaviour under moderate depth of cut. These geometrical choices help maintain dimensional accuracy and make toolpath planning more predictable on automated lathes.

Practical benefits for workshop efficiency and process security

Designed as an indexable insert for standard toolholders, the plate’s manufacturing tolerance class M and its A execution ensure interchangeability and repeatable clamping in series production. The Tiger‑tec Silver series is known for balancing wear resistance with toughness, providing a cost-effective solution where consistent results and low regrinding frequency are required. For workshops seeking to reduce downtime and simplify tooling logistics, this plate offers a dependable option that contributes to overall process security and productivity.
