SPMT120408-D51 WSM35G – Milling indexable insert, Tiger·tec Gold grade for rostfreier Stahl and superalloys (Walter Tools)

SPMT120408-D51 WSM35G is a square milling indexable insert engineered to support productive machining of challenging materials such as rostfreier Stahl and high-temperature alloys.

• Tiger·tec Gold coated carbide grade WSM35G
• Optimised chipbreaker D51 for chip control
• Square 90° insert with 0.8 corner radius
• Relief angle 11° for versatile milling

Longer tool life and consistent chip control for demanding alloys

The WSM35G grade, developed within the Tiger·tec Gold series, pairs a robust coating with a wear-resistant substrate to deliver extended tool life in severe applications. This combination reduces flank wear and supports stable chip formation, especially when machining tough-to-cut materials such as rostfreier Stahl and heat-resistant superalloys. The result is fewer tool changes, lower downtime and a more predictable production process. For operations that prioritise throughput, the coated carbide chemistry and the insert's geometry translate directly into improved process reliability and repeatable component quality.

Precision geometry to improve surface finish and cutting stability

The insert’s geometry is engineered for balanced performance: a Square 90° shape combined with a corner radius of 0.8 and a relief angle of 11° provides a robust cutting edge that resists chipping while still enabling good surface integrity. The D51 chipbreaker is optimised to break and evacuate chips reliably across common feeds used for rostfreier Stahl and titanium alloys, reducing the risk of built-up edge and tool-induced surface damage. These features help maintain consistent part tolerances and reduce the need for secondary finishing, contributing to lower cycle times and higher first-pass yields.

Practical advantages for shop-floor productivity and process control

In production environments where material variability and thermal loads are a concern, this insert offers a pragmatic balance of wear resistance and edge stability. The coated design supports higher cutting rates and prolonged cutting intervals compared with uncoated alternatives, which improves overall cost-efficiency per component. Combined with the insert’s chip control and geometry, users can expect steady machining parameters and fewer process interruptions.

FAQ

Which materials is this insert best suited for?
The SPMT120408-D51 WSM35G insert is designed for machining rostfreier Stahl and heat-resistant superalloys (ISO groups M and S), where its coating and grade support secure chip control and edge stability.

What is the function of the D51 chipbreaker?
The D51 chipbreaker promotes controlled chip segmentation and evacuation, reducing the risk of built-up edge and improving surface integrity when cutting at moderate to high feeds with coated carbide grades.

How do the geometry values affect performance?
The combination of a Square 90° format, 0.8 corner radius and 11° relief balances edge robustness with surface finish, helping to maintain dimensional accuracy and extend tool life under thermal load.

Is the grade coated and what benefit does the coating provide?
Yes — the insert uses the Tiger·tec Gold coating system. This coated carbide construction enhances heat resistance and wear protection, enabling longer tool life in demanding dry or wet cutting situations.

What tolerance and precision class does this insert meet?
The insert is supplied in tolerance class M, offering consistent geometry and repeatability suited to production milling of precision components.
