LDMT14T308R-F57 WKP25S — Indexable milling insert, Tiger·tec Silver for steel & cast iron (Walter Tools)

The LDMT14T308R-F57 WKP25S is a rectangular indexable milling insert engineered for productive face and shoulder milling in steel and cast iron, combining coated carbide performance with a chipbreaker optimised for controlled chip formation.

• Tiger·tec Silver coated carbide for long life
• Optimised for steel (P) and cast iron (K)
• 15° relief angle for stable cutting
• 0.8 mm corner radius for smooth finishes

Reliable performance on steel and cast iron

The combination of the Tiger·tec Silver technology and the WKP25S grade delivers a wear-resistant, coated-carbide solution that is designed to cope with the thermal and abrasive demands typical when machining steel (ISO group P) and cast iron (ISO group K). The coating and substrate pairing promote stable chip formation, reduced flank wear and consistent cutting forces, which together support longer tool life and fewer insert changes. The integrated chipbreaker F57 assists in breaking and evacuating chips to maintain process stability and reduce the risk of re-cutting.

Geometry tuned for accuracy and surface finish

A 15° relief promotes reliable entry and exit behaviour, reducing cutting edge stresses and vibration during interrupted cuts. The 0.8 mm corner radius helps to distribute cutting loads and improve workpiece surface quality without compromising strength at the cutting edge. The rectangular format (size 14) and T3 thickness provide a robust support platform in the tool holder, while the tolerance class M ensures consistent fit and repeatable seating for accurate machining and predictable part quality.

Process benefits and handling advantages

As an indexable milling insert, this product supports economical machining by offering multiple cutting edges per insert and straightforward replacement, lowering cost per component in volume production. The LDMT14T308R-F57 WKP25S belongs to the Tiger·tec Silver series, known for good overall process reliability and broad material coverage, making it suitable for mixed-production environments. The insert’s design reduces downtime for tool changes and aids in achieving reproducible results across batches, supporting higher productivity and simplified tool management.

FAQ

What materials is this insert suitable for?
The LDMT14T308R-F57 WKP25S is formulated for steel (ISO group P) and cast iron (ISO group K); the Tiger·tec Silver coating and WKP25S grade balance wear resistance and chip control for these groups.

How does the chipbreaker F57 affect machining?
The F57 chipbreaker promotes controlled chip formation and evacuation, reducing recutting and aiding stable machining when using the Walter Tools insert in interrupted or continuous cuts.

Which geometry features improve surface finish?
The 15° relief angle together with the 0.8 mm corner radius reduces cutting edge stress and vibration, contributing to improved surface quality and consistent part finishes.

Is this insert compatible with standard toolholders?
The rectangular LDMT geometry and T3 thickness are compatible with holders designed for LDMT-style inserts; proper clamping and seat cleanliness are recommended for repeatable accuracy with the Walter Tools insert.

What does the grade designation WKP25S indicate?
WKP25S denotes a Walter Tools coated-carbide grade within the Tiger·tec Silver range, optimised for productive machining of steel and cast iron with good wear resistance and stable cutting behaviour.
