SCMT120408-E47 WSM30S drilling/boring indexable insert by Walter Tools — Tiger·tec Silver coated, for stainless steel and superalloys

SCMT120408-E47 WSM30S is a square 90° indexable insert designed for demanding drilling and boring operations in stainless steel and heat‑resistant superalloys

• Tiger·tec Silver coating for heat resistance
• Optimised chipbreaker E47 for stable chips
• 0.8 mm corner radius for edge strength
• Square 90° geometry for versatile clamping

High‑performance cutting for demanding materials

The SCMT120408-E47 WSM30S insert pairs a coated carbide substrate with the Tiger·tec Silver technology to address the particular challenges of machining stainless steel and heat‑resistant superalloys. The combination of coating and substrate promotes stable chip formation and improved thermal resistance, which reduces the risk of built‑up edge and extends effective cutting life. For production environments where consistent surface quality and repeatability matter, this series provides a reliable balance between wear resistance and edge stability.

Geometry and chip control that stabilise the process

This insert’s chipbreaker E47 is engineered to produce controlled, repeatable chips under interrupted or heavy cutting conditions, reducing rework and downtime. The 7° relief angle and 0.8 mm corner radius support a robust cutting edge that resists deformation at elevated temperatures. The square 90° plate form distributes cutting forces evenly and enables multiple indexings per insert, contributing to lower tooling costs per component and a predictable tool change rhythm on automated machines.

Practical advantages on the shop floor

With a compact plate size and the specified plate thickness, the insert contributes to rigidity in the tool assembly and stable bore guidance during drilling and boring cycles. Its suitability for both stainless steel and high‑temperature alloys means fewer insert changes across mixed batches, simplifying inventory and process planning. The coated carbide and the Tiger·tec Silver finish help maintain consistent performance across medium to high cutting speeds, supporting higher productivity without compromising component finish.

Selection guidance for process security and productivity

Choosing an insert involves matching grade, geometry and chip control to the component material and cycle strategy. The WSM30S grade, as used here, emphasises thermal stability and edge robustness for tough‑to‑cut materials; combining this with the chipbreaker E47 and a 0.8 mm corner radius offers a practical route to minimise vibration and chatter in deeper bores. For application optimisation, consider machining parameters, coolant strategy and clamping stiffness to fully exploit the insert’s properties while maintaining process security.
