VCMT160404-RM4 WSM10S indexable turning insert for stainless steel and superalloys — Walter Tools

VCMT160404-RM4 WSM10S is an indexable turning insert engineered for heavy‑duty and high‑temperature turning applications, combining a coated carbide grade with a dedicated chipbreaker and a rhombic 35° geometry for controlled cutting in demanding materials

• Tiger·tec Silver coated grade WSM10S
• RM4 chipbreaker for controlled chips
• Rhombic 35° form with 0.4 mm corner
• Optimised for stainless steel and superalloys

High‑temperature performance for difficult‑to‑machine materials

The WSM10S grade, part of the Tiger·tec Silver family, is a coated carbide designed to resist thermal and mechanical wear when machining heat‑sensitive and tough materials. Its formulation supports stable chip formation and maintains a reliable cutting edge under elevated temperatures, which reduces unexpected tool changes and increases process uptime. For shops working with stainless steel or nickel‑based alloys, this means more consistent cycle times and fewer surface defects, while the coating contributes to prolonged tool life and repeatable performance.

Geometry that secures surface quality and chip control

The insert’s rhombic 35° shape combined with the RM4 chipbreaker and a 0.4 mm corner radius gives a balance between edge strength and finish capability. A clearance angle of 7° and the specified plate thickness ensure stable seating in standard tool holders and reduced vibration during interrupted cuts. The chipbreaker is optimised to break and evacuate swarf efficiently in combination with appropriate cutting data, supporting a reliable surface finish and minimising rework. These geometric choices make the insert suitable for both semi‑finish and finishing passes in production turning.

Production efficiency and consistent results on the shop floor

As an indexable turning insert, this product is aimed at manufacturers who prioritise repeatability and cost efficiency. The grade’s combination of wear resistance and edge stability reduces the frequency of insert changes and tool adjustments, supporting continuous operation and lower unit costs over long runs. From a process perspective, the insert contributes to higher machining stability and predictable tool life, which simplifies planning for replacement inserts and cutting parameters. Walter Tools’ proven platform and series integration help to ensure fast tool changeovers and consistent results across batches.

FAQ

What materials is this insert suitable for?
The VCMT160404‑RM4 WSM10S is formulated for S and M groups—primarily superalloys and stainless steel—offering heat resistance and edge stability for difficult‑to‑machine alloys.

Which geometry benefits finishing operations?
The rhombic 35° form with a 0.4 mm corner radius provides a compromise between edge strength and surface finish, making it suitable for semi‑finish and finishing passes.

How does the RM4 chipbreaker affect machining?
The RM4 chipbreaker promotes consistent chip control and evacuation, reducing the likelihood of built‑up edge and improving surface integrity under appropriate cutting conditions.

Is the insert compatible with standard toolholders?
The insert’s dimensions and clearance angle are aligned with ISO indexable turning standards, allowing use in common clamping systems for rhombic inserts.

What advantage does Tiger·tec Silver bring to production runs?
Tiger·tec Silver coating enhances thermal stability and wear resistance, which typically extends tool life and maintains cutting performance in longer production cycles.
