LDMT170408R-D57 WKP25S indexable milling insert — Tiger‑tec Silver, for Stahl & Gusseisen | Walter Tools

A LDMT170408R-D57 WKP25S indexable milling insert engineered for robust medium to heavy milling of Stahl and Gusseisen, offering enhanced tool life and stable chip formation.

• Tiger‑tec Silver coating for high wear resistance
• WKP25S grade optimised for Stahl and Gusseisen
• 15° clearance angle for stable cutting geometry
• Rectangular insert with 0.8 mm nose radius

Longer service life through advanced coating technology

The combination of the Tiger‑tec Silver coating and the WKP25S carbide grade delivers measurable improvements in abrasion resistance and edge stability. Coating technology reduces flank wear under elevated temperatures common when machining Stahl, which translates into longer intervals between index changes and lower tooling costs per component. For operations that require sustained productivity, the coated insert supports consistent performance across batch runs and helps maintain machining parameters without frequent adjustment.

Consistent chip control and improved surface finish

Equipped with the D57 chipbreaker and a rectangular form, the insert promotes repeatable chip formation, which reduces the risk of built-up edge and interruptions. The 0.8 mm nose radius contributes to a balance between edge strength and surface integrity, enabling good component finish while resisting chipping in interrupted cuts. Stable chip evacuation reduces tool wear and the potential for rework, supporting higher first-pass yields on cast and steel components.

Precision geometry for process security and productivity

The insert's 15° clearance angle and robust edge geometry ensure a defined cutting relationship that is less sensitive to machine vibrations and fixture variations. This geometry supports reliable indexability and repeatability in multi‑tool setups, shortening changeover time compared with re‑grindable tools. As a result, the insert offers a pragmatic route to increased spindle utilisation and consistent cycle times in series production.

Practical integration into production workflows

As a standard rectangular indexable insert, the component is compatible with common cutter bodies that accept the LDMT footprint, enabling fast replacement and simplified inventory management. The combination of coated carbide material and optimised chip control reduces the need for excessive cutting parameter adjustments, freeing up engineering time for other process improvements. For specific machine or application questions, technical advice is available to ensure optimal tool selection and parameter settings.

FAQ

Is this insert suitable for machining steel?
The LDMT170408R-D57 WKP25S from Walter Tools is designed for machining Stahl (ISO group P) and is optimised to handle the heat and chip behaviour typical of steel cutting.

Can this insert be used for cast iron workpieces?
Yes. The WKP25S grade and the D57 chipbreaker are configured for effective chip control when machining Gusseisen, providing stable cutting and good wear resistance.

What advantages does Tiger‑tec Silver provide?
The Tiger‑tec Silver coating improves abrasion resistance and edge life, which enhances process security and reduces the frequency of index changes in serial milling applications.

What do the 0.8 mm radius and 15° clearance deliver in practice?
A 0.8 mm corner radius gives improved edge robustness for interrupted cuts, while the 15° clearance angle establishes a stable cutting geometry that supports repeatable machining results.

Is the insert recommended for rostfreier Stahl (stainless steel)?
No specification for rostfreier Stahl is provided for this grade; the LDMT170408R-D57 WKP25S is specified for Stahl and Gusseisen only.
