Faster, more reliable machining through a modern coating system

The combination of Tiger·tec Silver technology and the WKP35S grade delivers a clear advantage in cyclic drilling and boring. The coated carbide composition provides improved resistance to abrasive wear and thermal loading typical of steel and cast iron operations, which translates into longer intervals between tool changes and more stable production runs. This translates to tangible gains in productivity and fewer process interruptions during batch production.

Consistent chip control and stable cutting behaviour

The insert’s geometry, denoted by 6R-F57, incorporates a chipbreaker designed to manage the short, brittle chips commonly produced when machining cast components, while also performing reliably in steel. The engineered chip formation reduces the risk of chip jamming and improves surface finish consistency, supporting higher feed rates where tool holders and machine rigidity allow. Improved chip control directly supports process reliability and predictable cycle times.

Practical benefits for workshop workflows

As an indexable cutting solution, the insert simplifies inventory management compared with brazed or solid tools: the WKP35S grade and the Tiger·tec Silver coating aim to deliver repeatable performance and easier replacement. For production planning, this means fewer unexpected tool failures and a clearer basis for estimating tool life under defined cutting parameters. The insert is intended for use in compatible drilling and boring tool bodies that accept this ISO designation; confirmation of seat geometry and clamping method is recommended before mounting.

What the grade and series mean for application choice

The designation signals suitability primarily for workpieces classified under ISO group P (unalloyed and alloyed steel) and K (cast iron). The WKP35S coated carbide was selected to balance wear resistance and toughness for these materials, helping to maintain edge integrity under the heat and abrasion typical of such cuts. Where very different materials or extreme hardness levels are involved, assess tool selection accordingly rather than assuming universal applicability.

FAQ

What materials is this insert suited for?
The P4840C-6R-F57 WKP35S insert from Walter Tools is intended primarily for steel (ISO group P) and cast iron (ISO group K), reflecting the design priorities of the WKP35S grade and Tiger·tec Silver coating.

Is this insert suitable for stainless steel?
No, the WKP35S grade and this geometry are optimised for steel and cast iron; machining stainless steels usually requires different grades and coatings tailored to their work‑hardening behaviour.

What does the Tiger·tec Silver designation mean?
Tiger·tec Silver denotes a modern PVD/CVD coating technology combined with a carbide substrate to improve wear resistance and thermal stability, supporting longer tool life and consistent cutting performance in the specified materials.

Which tool holders accept this insert designation?
The insert is meant for drilling and boring tool bodies compatible with the ISO/geometry designation P4840C-6R-F57; confirmation of seat type and clamping method is recommended before fitting.

Can these inserts be resharpened or reconditioned?
Indexable inserts such as the WKP35S are manufactured as replaceable cutting edges and are not typically reground; replacement is the standard procedure when wear affects performance.
