• Optimised for steel machining
• Suitable for cast iron components
• Chipbreaker 2R25-D57 for stable chips

Maximise throughput on steel and cast iron

The combination of the Tiger·tec Silver coating with the WKP25S carbide grade provides a balance of wear resistance and toughness that is particularly suited to the thermal and mechanical demands of machining steel (ISO group P) and cast iron (ISO group K). The coating reduces abrasive wear and helps maintain cutting-edge integrity under the high temperatures commonly encountered in production runs. For production environments where uptime and repeatable part quality matter, this specification supports longer tool life and fewer index changes, which contributes directly to lower overall machining costs per component.

Consistent edge life and process security

Coated cemented carbide in the WKP25S class was developed to offer predictable performance across a range of common steels and cast irons. The material and coating combination improves edge life and reduces the frequency of unplanned interruptions due to wear-related edge failure. This leads to greater process security, with more predictable tool-change intervals and stable dimensional results. The insert’s design aims to ensure economical performance over series production, helping to maintain surface quality and part tolerances without excessive tooling overhead.

Controlled chip formation for stable productivity

The chipbreaker 2R25-D57 is engineered to influence chip geometry and evacuation in interrupted and continuous cuts. By promoting short, controllable chips, the geometry reduces the risk of chip entanglement and improves safety at higher cutting speeds. Effective chip control also assists in preserving surface finish and in maintaining consistent cutting forces, which benefits machine tool spindle life and fixture stability. For operators less familiar with chipbreaker nomenclature: this designation identifies the insert’s groove and facet geometry, optimised for a balance of shear and compression suited to P and K materials.

Practical application and compatibility overview

This indexable milling insert is supplied as a standard plate designed for versatile incorporation into common milling tool bodies where the specific seat and clamping system accept the P44290-series geometry. The main application is catalogue- and geometry-dependent, meaning the cutting performance will be governed by the chosen tool holder, entry conditions and machine rigidity. For unfamiliar set-ups, matching the WKP25S grade and Tiger·tec Silver coating to the machining strategy offers a reliable starting point for achieving repeatable productivity and stable surface integrity.

FAQ

What materials is this insert intended for? The P44290-2R25-D57 WKP25S insert is intended primarily for steel (ISO P) and cast iron (ISO K) machining, reflecting the grade and coating combination.

What advantages does Tiger·tec Silver provide? Tiger·tec Silver is a coating technology applied to cemented carbide that enhances abrasive-wear resistance and thermal stability, improving edge life and consistent performance in the relevant material groups.

What is the function of the 2R25-D57 chipbreaker? The 2R25-D57 chipbreaker shapes chip flow to produce short, controllable chips and to assist in evacuation from the cutting zone, supporting surface quality and reducing the risk of chip-related interruptions.

Is this insert suitable for finishing operations? Finishing suitability depends on the specific tool geometry and the depth of cut; the WKP25S grade can be used in a range of operations, but the final surface finish will be influenced by the chosen holder and cutting parameters.

Can the insert be re-sharpened or reconditioned? Indexable inserts of this type are typically not re-sharpened; performance is achieved through replacing with a new insert of the same grade and geometry to maintain process reliability.
