P4160-2L08-E47 WKK20S drilling/reaming indexable insert — Tiger·tec Silver for cast iron (Walter Tools)

The P4160-2L08-E47 WKK20S is an indexable insert designed for drill and reaming applications, optimised for machining cast iron in serial production environments.

• Tiger·tec Silver coating for wear resistance
• WKK20S grade optimised for cast iron
• Stable chip formation with 2L08-E47 breaker
• Coated carbide for reliable tool life

Extended component life through targeted coating technology

The combination of Tiger·tec Silver and the WKK20S grade delivers measurable benefits when working with cast iron: the coating reduces abrasive wear and helps maintain a stable cutting edge, which directly extends tool life and reduces downtime. For operations that face frequent edge wear due to hard inclusions or abrasive graphite, this coating-grade pairing minimises the frequency of index changes and supports continuous cycles, increasing overall throughput while keeping maintenance predictable.

Reliable chip control for fewer process interruptions

Equipped with the 2L08-E47 chipbreaker, the insert produces short, controlled chips that prevent accumulation in the bore and reduce the risk of tool jamming. Improved chip control translates into fewer interruptions and less manual clearing during longer drilling or reaming passes, which enhances process security and results in more consistent part quality. The chip geometry is tuned for brittle, breaking-chip materials typical of the ISO K group, aiding stable machining even in interrupted cuts.

Practical production benefits and inventory simplicity

As a coated carbide insert tailored to the ISO K category, the component simplifies tool selection for cast-iron workpieces and supports predictable cycle times in batch production. The universality of the WKK20S grade for cast-iron applications reduces the need for multiple special-purpose grades, improving inventory management and ensuring fast tool changeovers. The design promotes reproducible surface finish and dimensional consistency, making it suitable for workshops focused on reliable, efficient machining rather than frequent process optimisation.

FAQ

What materials is this insert designed for?
The insert is designed for cast iron machining; the WKK20S grade and Tiger·tec Silver coating are optimised for the abrasive and short-chip properties of ISO K materials.

How does the 2L08-E47 chipbreaker improve performance?
The 2L08-E47 chipbreaker produces controlled, short chips that reduce bore clogging and lower the likelihood of tool stoppages during drilling and reaming.

Is this insert suitable for interrupted cuts in cast iron?
Yes, the combination of coated carbide and the WKK20S grade provides resilience against the mechanical shocks common in interrupted cuts on cast iron.

Will this insert improve surface finish on cast-iron components?
The coating and stable cutting geometry help deliver consistent surface results by maintaining edge integrity, which contributes to improved finish over long runs.

Can the insert be used across different sizes of drills and holders?
The insert is an indexable component intended for compatible drilling/reaming systems; confirm holder compatibility and seat dimensions before selection.
