WNMG100612-MK5 WKK10S — Indexable Turning Insert, Tiger‑tec Silver, for Cast Iron (Trigon 80°) — Walter Tools

The WNMG100612-MK5 WKK10S is a trigon indexable insert from the Tiger‑tec Silver series, engineered with a negative 0° rake to deliver consistent performance when machining cast iron components.

• Tiger‑tec Silver coating for high wear resistance
• Optimised for cast‑iron machining (ISO K)
• Trigon 80° form with 1.2 mm corner radius
• MK5 chipbreaker for reliable chip control

Higher productivity through coating and grade benefits

The Tiger‑tec Silver grade WKK10S combines a wear‑resistant coated carbide body with geometry tuned for brittle, abrasive cast‑iron chips. This results in reduced flank wear and a more consistent tool life, meaning fewer interruptions for insert changes and a steadier production rhythm. The coated hardmetal substrate offers a balance of wear resistance and toughness that is particularly beneficial for interrupted cuts and variable surface conditions often encountered on cast‑iron workpieces. By matching the grade to the material group, process stability and repeatable surface quality are improved.

Secure cutting behaviour and dependable chip management

Built with an MK5 chipbreaker and a Trigon 80° shape, the insert provides controlled chip formation and evacuation in short, brittle chips typical of cast iron. The MK5 geometry promotes predictable chip flow and reduces the risk of entanglement, while the trigon form gives strong cutting edges and effective insert seating in standard WNMG pockets. The negative 0° rake enhances edge robustness under heavy cuts, supporting stable cutting forces and lowering the likelihood of edge chipping. These characteristics translate into fewer rejects and more reliable cycle times for batch and serial production.

Practical mounting and consistent positioning for workshop use

Tolerance class M and a corner radius of 1.2 mm ensure consistent seating and repeatable edge position in the toolholder, which simplifies process setup and inspection routines. The insert’s dimensions and the thickness code support rigid clamping, while the grade’s balance of abrasion resistance and toughness helps maintain cutting performance across diverse cast‑iron grades. Reduced variability in edge condition shortens downtime for adjustments and contributes to overall machining economy, making this insert a practical choice for shops aiming to improve uptime and reproducibility.

FAQ

Is this insert suitable for cast‑iron components?
Yes. The WNMG100612-MK5 WKK10S from Walter Tools is specifically optimised for cast‑iron (ISO group K) machining and matched to the abrasive, short‑chip behaviour of such materials.

What advantages does the Tiger‑tec Silver grade offer?
Tiger‑tec Silver provides a coated carbide surface that increases wear resistance, enhances edge life under abrasive conditions and helps maintain consistent surface finish during extended production runs.

How does the MK5 chipbreaker affect performance?
The MK5 chipbreaker promotes controlled chip formation and evacuation for short, brittle chips typical of cast iron, improving process reliability and reducing the risk of chip interference.

Can the trigon form be used in standard WNMG toolholders?
Yes. The Trigon 80° geometry is compatible with standard WNMG pockets and offers a strong cutting edge for heavy interruptions and stable clamping.
