SPEB090308-A67 WSM35G indexable milling insert — Tiger·tec Gold, square 90° (Walter Tools)

The SPEB090308-A67 WSM35G is an indexable milling insert engineered for machining stainless steels and heat‑resistant superalloys, offering a balance of edge stability and wear resistance within the Tiger·tec Gold family.

• Tiger·tec Gold coating for high thermal stability
• Optimised chipformer A67 for secure chip control
• Square 90° form with 0.8 mm corner radius
• Suited to stainless steel and superalloys (M, S)

Greater productivity through thermal stability and wear resistance

The Tiger·tec Gold combination of a coated carbide substrate and modern multilayer coating provides enhanced thermal stability and wear resistance during heavy or interrupted cuts. This means more consistent tool life in applications with elevated cutting temperatures and tendencies to build up on the edge. The result is a reduction in unplanned tool changes and a steadier production rhythm when machining stainless steels and nickel‑based alloys, where heat and ductility strain the cutting edge.

Reliable chip control and geometric advantages for safer machining

Thanks to the designated A67 chipformer and the square 90° geometry, chip evacuation is more predictable and chips are broken into manageable segments, lowering the risk of re‑cutting and surface damage. The corner radius R0.8 mm and the relief angle 11° together promote a robust cutting edge that tolerates higher feed rates while maintaining acceptable surface finish. For workshops seeking repeatable results, this combination supports stable process windows and easier optimisation of cutting data.

Purposeful grade selection for demanding materials

The WSM35G grade is a coated carbide designed specifically for the M and S ISO groups: M denotes stainless steels, which require secure chip formation and chipping resistance; S covers heat‑resistant superalloys and titanium, demanding excellent edge stability and heat resistance. Selecting this grade reduces the compromise between tool life and component integrity, providing a predictable balance between wear performance and cutting reliability for difficult‑to‑machine alloys.

Integration into machining processes and shopfloor benefits

As a square insert with a compact thickness and standard size code, the insert integrates easily into conventional milling holders and indexable cutter systems, enabling quick index changes and minimal setup time. The tolerance class E and the execution B ensure consistent seating in the pocket and reproducible running behaviour, which simplifies process documentation and quality control. For production runs where downtime must be minimised, this insert supports higher availability and simplified tooling logistics.

FAQ

What materials is this insert suitable for?
The SPEB090308-A67 WSM35G insert is formulated for stainless steels (ISO group M) and heat‑resistant superalloys/titanium alloys (ISO group S).

How does the Tiger·tec Gold coating benefit shopfloor performance?
The Tiger·tec Gold coating on the WSM35G grade increases thermal stability and wear resistance, which extends effective tool life and supports higher cutting temperatures often encountered in machining stainless steels and superalloys.

What does the A67 chipformer provide during milling?
The A67 chipformer promotes consistent chip breaking and evacuation, reducing the likelihood of long, tangled chips and helping to protect the workpiece surface from recutting and damage.

Is the square 90° geometry suitable for heavy interrupted cuts?
The square 90° configuration combined with a 0.8 mm corner radius and a robust grade gives the insert good edge strength, making it suitable for a range of milling tasks including moderate interrupted cuts when mounted in appropriate tooling.

Which machineholders are compatible with this insert?
The SPEB090308-A67 WSM35G follows standard indexable insert dimensions and fits conventional milling cutter systems that accept a 09 size square insert; confirm holder compatibility and clamping standards before use.
