CPGT050204-MM4 WSM20S drilling/turning indexable insert, Tiger·tec Silver – Walter Tools

A CPGT050204-MM4 WSM20S insert designed for high‑temperature alloy and stainless‑steel machining in turning and drilling operations.

• Tiger·tec Silver coated carbide for heat resistance
• Optimised for stainless steels and superalloys
• Rhombic 80° geometry for versatile turning and drilling
• 11° clearance with 0.4 mm corner radius

High‑performance grade for challenging materials

The insert combines the WSM20S carbide grade and Tiger·tec Silver technology to deliver enhanced thermal stability and edge life when cutting tough materials. As a coated carbide insert, it supports secure chip formation and reduced built‑up edge during intermittent or continuous cuts; this is particularly valuable when machining stainless steels and nickel‑based superalloys, which generate high temperatures and stress the cutting edge. The specification CPGT050204‑MM4 defines the insert footprint and makes it suitable for integration in common turning and drilling toolholders where a rhombic shape is required.

Geometry and edge design that improve process reliability

The Rhombic 80° form offers a balance between cutting strength and accessibility in shoulder, facing and light boring tasks. The specified 11° clearance reduces rubbing and heat generation at the flank, while the 0.4 mm corner radius supports a robust edge that can withstand higher feed rates without premature chipping. The MM4 chipbreaker geometry promotes consistent chip segmentation, which simplifies evacuation in through‑tool and external machining. Together, these characteristics reduce unplanned tool changes and contribute to a steadier production flow.

Productivity benefits and cost‑effectiveness in serial production

Using a dedicated grade and optimised geometry means fewer interruptions for tool change and less scrap from poor surface finish. The combination of coating and grade yields longer tool life and more consistent part quality, which translates into lower unit costs in batch and continuous manufacture. The insert’s attributes support higher cutting speeds where application permits and help maintain dimensional repeatability across components. For operations aiming to raise throughput without compromising surface integrity, this insert provides a pragmatic upgrade.

Integration into tooling systems and application guidance

The insert is compatible with standard turning and drill holders accepting the CPGT form factor; selection of the correct seat and clamp influences performance, so secure clamping and correct orientation are essential. For machining stainless steels and heat‑resistant alloys, adopt stable setups, appropriate coolant strategies and modest depths of cut when approaching material limits. The grade and chipbreaker suit both intermittent and continuous cuts depending on holder rigidity, so pairing with a rigid toolbody will maximise the benefits of the Tiger·tec Silver technology and the WSM20S composition without compromising surface finish.
