WOEX080408-E57 WKP25S – indexable drilling/bore insert, Trigon 80°, Tiger·tec Silver (Walter Tools)

A WOEX080408-E57 WKP25S is an indexable insert engineered for drilling and bore enlargement in steel and cast iron, combining a Trigon 80° form with the Tiger·tec Silver coated carbide for extended tool life and consistent chip control.

• Tiger·tec Silver coating for high wear resistance
• WKP25S grade optimised for steel and cast iron
• Trigon 80° geometry for stable cutting performance
• Corner radius 0.8 mm for reliable edge strength

Higher uptime through advanced coating and grade

The combination of Tiger·tec Silver technology and the WKP25S coated carbide grade delivers markedly improved wear resistance compared with uncoated grades. This coating system is developed for elevated thermal and abrasive loads encountered when machining steel and cast iron, converting material-specific heat and abrasion into predictable tool life. The result is fewer insert changes and more consistent cycle times—advantages that translate directly into higher machine availability and lower per-part tooling cost.

One insert for steel and cast-iron operations

Designed for the ISO material groups P and K, this insert supports efficient processing of steel (P) and cast iron (K) with a single geometry and grade. The WKP25S chemistry is tuned to manage the typical chip formation and heat patterns of these groups, reducing the need to switch grades between different workpieces. For production environments that handle mixed batches or varied components, this versatility reduces inventory complexity and simplifies process planning.

Geometry that stabilises cutting and improves surface quality

The Trigon 80° form offers a robust cutting edge and an insert shape that promotes stable engagement during drilling and bore enlargement. Combined with a corner radius 0.8 mm, the geometry increases edge strength and resists chipping under intermittent entry conditions. The chipbreaker E57 supports controlled chip formation, particularly beneficial where short or brittle chips are expected, improving evacuation and reducing the risk of re-cutting. These geometric choices help lower vibration and improve surface finish on demanding bores.

Practical benefits for workshop integration

As an indexable insert from the Tiger·tec Silver series, the component is compatible with standard machining workflows and established holder systems, enabling quick seat changes and predictable repeatability. The insert’s profile and grade are selected to support productive drilling cycles and stable tool life, which aids in planning preventive maintenance and minimising unplanned downtime. Where process reliability and consistent results are priorities, this insert offers a balance of performance and economy that fits production-focused environments.

FAQ

What materials is this insert suitable for?
The WOEX080408-E57 WKP25S is formulated for steel (ISO group P) and cast iron (ISO group K), offering balanced performance across both material families.

What benefit does the Tiger·tec Silver coating provide?
Tiger·tec Silver on the WKP25S grade enhances thermal and abrasive resistance, increasing insert life and stabilising cutting conditions in demanding operations.

How does the Trigon 80° form affect machining?
The Trigon 80° geometry improves edge support and cutting stability during drilling and bore enlargement, reducing vibration and promoting consistent surface finish.

What role does the chipbreaker E57 play?
The E57 chipbreaker controls chip formation for short, brittle chips—particularly useful when machining cast iron—helping to avoid chip entanglement and improve evacuation.

Is the corner radius suitable for interrupted cuts?
With a corner radius of 0.8 mm, the insert provides enhanced edge strength that resists chipping under intermittent entry, making it appropriate for less continuous engagement.
