SDMT120425-F57 WSM35G Fräswendeschneidplatte (Square 90°, R2.5) by Walter Tools

SDMT120425-F57 WSM35G is a square milling indexable insert designed for demanding work in rostfreier Stahl and heat-resistant alloys, combining Tiger·tec Gold coating with a robust geometry for reliable material removal

Tiger·tec Gold coated carbide grade WSM35G
Optimised for rostfreier Stahl and superalloys
Square 90° insert with 2.5 mm corner radius
15° clearance and F57 chipbreaker design

Reliable performance in rostfreier Stahl and superalloys

The SDMT120425-F57 WSM35G insert is built on the Tiger·tec Gold coating platform and the WSM35G cutting grade to address the thermal and mechanical stresses of machining rostfreier Stahl and high-temperature alloys. The coated carbide substrate increases resistance to abrasive wear and heat, which reduces the formation of built-up edge and extends tool life. For operations where thermal load is high, this combination supports stable chip formation and predictable wear patterns, thereby improving machining consistency and reducing unplanned tool changes.

Controlled chips and improved surface quality

The engineered F57 chipbreaker geometry promotes short, controllable chips even when cutting sticky or ductile materials. Shorter chips reduce the risk of entanglement and make chip evacuation more reliable, which contributes to a better surface finish and fewer interruptions on automated lines. In process terms, the chipbreaker reduces cutting forces peaks and supports continuous material flow from the cutting zone, helping to maintain steady spindle loads and consistent part quality during longer production runs.

Geometry that supports strength and accuracy

A square 90° shape with a 2.5 mm corner radius and 15° clearance delivers a balance between edge strength and cutting precision. The larger corner radius increases edge robustness for heavier engagement, while the defined clearance angle helps prevent rubbing and heat build-up on the flank. The insert’s thickness code and M tolerance class ensure repeatable seating and positioning in compatible toolholders, which is essential for maintaining dimensional accuracy across batches and for predictable tool indexing cycles.

Practical application and efficiency gains

Assigned to material groups S / M under ISO 513, this insert is suited to heavy-duty and high-heat tasks as well as many stainless steel applications depending on the chosen tool geometry. The combined effect of the coating, grade and chipbreaker is improved productivity through longer cutting intervals and reduced downtime for tool change. For production environments prioritising process stability and cycle-time efficiency, this grade offers a cost-effective way to extend operating windows and increase machine utilisation without sacrificing surface integrity.

FAQ

What materials is this insert designed for?
The SDMT120425-F57 WSM35G insert from Walter Tools is formulated for rostfreier Stahl and heat-resistant superalloys (ISO groups M and S), offering thermal stability and wear resistance for difficult-to-cut materials.

How does the F57 chipbreaker help production?
The F57 chipbreaker on the SDMT120425-F57 reduces chip length and manages chip evacuation, which improves the surface finish and lowers the risk of chip-related stoppages during continuous milling operations.

What is the effect of the 2.5 mm corner radius?
A 2.5 mm corner radius increases edge strength for heavier cutting engagements and supports longer tool life; in the SDMT120425-F57 this contributes to more tolerant cutting conditions and fewer tool changes.

Which dimensions and tolerance class apply to this insert?
The insert is a square 90° type with size 12, thickness code 04 and tolerance class M; these parameters ensure stable seating and reproducible indexing in matching toolholders.

Is this insert suitable for finishing or roughing operations?
The WSM35G grade and Tiger·tec Gold coating target high thermal and mechanical stresses, making the SDMT120425-F57 suitable for heavy-duty cutting; depending on tool geometry, it can also be applied to finishing tasks in rostfreier Stahl.
