XDMT4009250R-F55 WKP35S – Indexable milling insert (for steel and cast iron) by Walter Tools

The XDMT4009250R-F55 WKP35S indexable milling insert is engineered for productive roughing and semi-finishing of steel and cast iron, combining a Tiger·tec Silver coating with a tailored geometry for stable machining.

• Tiger·tec Silver coating technology
• Grade WKP35S, coated carbide
• For steel and cast iron machining
• 2.5 mm corner radius for robust edge

Increase throughput with consistent cutting performance

The combination of a coated carbide grade and the Tiger·tec Silver technology delivers a measurable increase in process reliability for demanding milling tasks. The insert’s chipbreaker F55 is optimised to manage the typical chips produced when machining steel and cast iron, reducing interruptions from chip entanglement and improving machine utilisation. By favouring stable chip formation and predictable wear behaviour, this geometry supports higher uninterrupted cutting times and a more efficient production flow. The result is a practical uplift in productivity while maintaining surface quality.

Prolonged edge life through optimised coating and geometry

Constructed from a wear-resistant WKP35S substrate and finished with a Tiger·tec Silver coating, the insert provides improved resistance to abrasive and adhesive wear mechanisms common in ferrous materials. The substantial 2.5 mm corner radius increases edge strength, delaying corner chipping in interrupted cuts and roughing operations. A 15° clearance angle supports secure cutting engagement while reducing rubbing and heat build-up at the flank, thereby helping to extend the component life of the insert and reduce tool change frequency.

Precision results across typical shop-floor applications

With a standard ISO designation and a tolerance class M, the insert offers reproducible geometry suitable for fixture-based production and versatile milling setups. The nominal plate size value (40) and thickness code (09) define a stable contact surface in the tool holder, which helps maintain consistent runout and repeatability across series production. For shops working to ISO material groupings, the marked suitability for P (steel) and K (cast iron) clarifies application scope and supports tool selection decisions without guesswork.

Practical handling and application notes for machining planners

The indexable design supports rapid replacement and minimises downtime compared with regrindable solutions, making it suitable for batch-oriented environments and general workshop use. The WKP35S grade is intended for the thermal and mechanical conditions of steel and cast iron cutting; when used with appropriate holder clamping and process parameters the insert delivers steady performance. For mixed production that includes both unalloyed steels and abrasive cast materials, the combination of chip control and coating technology reduces risk of premature wear and enhances overall process security.

FAQ

What materials is this insert suitable for?
The insert is specified for machining steel (P) and cast iron (K); the WKP35S grade and Tiger·tec Silver coating are designed to cope with the thermal and abrasive conditions of these materials.

What does the F55 chipbreaker provide?
The F55 chipbreaker offers controlled chip formation for roughing and semi-finishing, improving evacuation and reducing the risk of chip-related interruptions during milling.

How does the 2.5 mm corner radius affect performance?
A 2.5 mm corner radius increases edge robustness for interrupted cuts and heavy engagement, helping to prolong edge life and reduce the frequency of insert replacements.

What is the significance of the 15° clearance angle?
The 15° clearance angle reduces flank contact and rubbing while maintaining a secure cutting edge engagement, which helps lower heat generation and wear on the flank face.

Is this insert available across a complete tooling system?
The insert form and ISO designation align with common indexable milling systems; selection of the correct holder and clamping system will ensure optimal performance with the XDMT4009250R-F55 WKP35S insert.
