SPMT09T308-D51 WSM35G – Square milling indexable insert, Tiger·tec Gold, for rostfreier Stahl and superalloys (Walter Tools)

SPMT09T308-D51 WSM35G is a square 90° indexable insert designed for productive face and shoulder milling of tough-to-machine materials, combining a heat‑resistant coating and geometry tuned for stable cutting.

• Tiger·tec Gold coated for elevated thermal resistance
• Suitable for rostfreier Stahl and heat‑resistant superalloys
• 11° clearance angle for secure chip control
• 0.8 mm corner radius for robust cutting edges

Robust performance for demanding materials

The insert’s WSM35G grade, developed within the Tiger·tec Gold series, is formulated for use on rostfreier Stahl and heat‑resistant superalloys. This coating technology increases thermal stability and abrasion resistance, which supports stable chip formation and reduces the risk of built‑up edge under elevated temperatures. For operations where material adhesion and heat are primary concerns, the combined grade and coating deliver a more consistent cutting action and longer edge life compared with uncoated alternatives. The result is improved process reliability and fewer interruptions for index changes, translating into higher productivity on challenging workpieces.

Geometry engineered for reproducible accuracy

The square 90° plateform with an 11° clearance angle and a 0.8 mm corner radius provides a compromise between edge strength and precision. The clearance angle reduces rubbing and heat input to the flank, while the corner radius supports robust load distribution at the cutting edge, which is particularly beneficial in interrupted cuts or heavier engagement. The plate thickness T3 and tolerance class M contribute to consistent clamping behaviour and repeatable positioning in standard tool holders. Together, these geometric parameters help maintain component tolerances and surface quality while offering predictable tool life for serial and jobbing operations.

Practical advantages for machining and process security

Equipped with a D51 chipbreaker, the insert manages chips effectively during milling of tough alloys, helping to avoid problematic long chips and improving evacuation in confined fixtures. The insert’s square form provides four cutting edges per index, reducing tooling costs per edge and simplifying inventory management. For production environments seeking steady cycle times and stable quality, this solution offers an economical path to improved throughput without compromising surface integrity. If cutting‑parameter fine‑tuning is required for specific grades of rostfreier Stahl or exotic alloys, technical consultation is recommended to match speeds, feeds and engagement to the workpiece and machine capabilities.

FAQ

What materials is this insert designed for?
The insert is intended for machining rostfreier Stahl and heat‑resistant superalloys (material groups S and M); the WSM35G grade and Tiger·tec Gold coating provide the thermal and edge stability required for these materials.

How does the 0.8 mm corner radius affect component finish?
A 0.8 mm corner radius increases edge strength and helps maintain consistent surface finish under higher loads; this radius supports stable cutting in both continuous and interrupted milling operations.

What advantages does the D51 chipbreaker provide?
The D51 chipbreaker promotes controlled chip formation and improved evacuation during milling of sticky or high‑temperature alloys, lowering the risk of chip entanglement and improving process security.

Is the insert compatible with standard square 90° milling holders?
The insert is a square 90° design and is suitable for holders that accept SPMT‑style indexable plates; ensure holder seat and clamping specifications match the SPMT09T308‑D51 geometry.

How many cutting edges are available per insert?
The square plate provides up to four indexable cutting edges, enabling economical use and simplified inventory rotation of cutting edges.
