P2840S-3N-A57 WKP35S — Bohr-/Aufbohrwendeschneidplatte (Tiger·tec Silver) for steel & cast iron — Walter Tools

P2840S-3N-A57 WKP35S is an indexable insert designed for bored and re-boring operations, optimised to deliver consistent cutting performance in steel and cast iron applications.

• Tiger·tec Silver coating for wear resistance
• WKP35S grade for stable cutting edge
• Optimised for steel and cast iron machining
• Consistent chip formation and process security

Proven coating and grade for extended tool life

The combination of the Tiger·tec Silver coating and the WKP35S carbide grade yields a wear-resistant cutting edge that tolerates the thermal and mechanical loads typical of steel machining. Coated carbide inserts balance toughness and hardness: the substrate provides fracture resistance while the coating reduces adhesive and abrasive wear. The result is fewer tool changes and a more predictable replacement interval, which supports higher machine uptime and lower production costs. This behaviour is particularly valuable in serial boring where cycle consistency matters.

Geometry and chip control that stabilise the process

The 3N-A57 chipbreaker geometry is tuned to the breaking behaviour of both steel (ISO group P) and cast iron (ISO group K). Controlled chip formation prevents long, stringy swarf and reduces the risk of tool and workpiece damage. Stable chip behaviour also improves coolant interaction and eases swarf handling at the machine, contributing to safer, cleaner production. The insert’s geometry stabilises cutting forces and supports process security, especially during medium to heavy depth cuts.

Operational benefits for the modern workshop

As an indexable insert intended for boring and re-boring tasks, the design emphasises predictable performance and economic machining. Reduced flank wear and stable cutting edges translate into fewer interruptions for regrinding or replacement. This insert supports higher throughput through longer effective tool life and consistent surface finish, helping to meet tighter tolerance chains without excessive tool inventories. Compatibility with standard boring toolholders ensures fast installation and immediate integration into existing setups.

FAQ

What materials is this insert suitable for?
The P2840S-3N-A57 WKP35S insert is developed for steel (ISO group P) and cast iron (ISO group K), providing reliable wear behaviour for both material classes.

What benefit does the Tiger·tec Silver coating provide?
Tiger·tec Silver reduces abrasive and adhesive wear on the cutting edge, extending the insert’s service life and maintaining cutting performance under typical steel and cast iron machining conditions.

How does the 3N-A57 chipbreaker support production?
The 3N-A57 geometry promotes controlled chip breaking for medium to heavy cuts, improving swarf handling and reducing the likelihood of built-up edge or tool damage during boring operations.

Is the WKP35S grade suitable for high-speed applications?
WKP35S is a coated carbide grade engineered for stability and wear resistance; its suitability for elevated cutting speeds depends on the specific machining parameters and must be validated in trial cuts for each application.

How is the insert identified and matched to toolholders?
Identification is by the full designation P2840S-3N-A57 WKP35S; compatibility with standard boring toolholders is common, but verification against the holder’s insert seat and clamping is recommended before production use.
