SCMT09T308-RM4 WSM10S turning and drilling insert — Walter Tools, Tiger·tec Silver, RM4 chipbreaker

SCMT09T308-RM4 WSM10S is a multi‑purpose indexable insert designed for demanding machining of heat‑resistant alloys and stainless steel in turning and drilling operations

• Tiger·tec Silver coated for high thermal resistance
• WSM10S grade for tough, heat‑resistant materials
• RM4 chipbreaker for controlled chip formation
• Square 90° form for stable seat and cutting edge

Consistent performance on tough, heat‑resistant materials

The combination of the WSM10S grade with the Tiger·tec Silver coating delivers a reliable balance between thermal resistance and wear protection. This insert is optimised for materials classified under ISO group M (stainless steel) and S (heat‑resistant superalloys and titanium), where workpiece toughness and poor thermal conductivity demand a coated, robust carbide. The result is stable chip formation and reduced edge breakdown, which translates into fewer tool changes and more predictable production cycles.

Secure chip control and edge stability for safer machining

With the engineered RM4 chipbreaker and a 0.8 mm corner radius, the insert supports predictable chip evacuation and a durable cutting edge under intermittent loads. The specified 7° clearance angle reduces rubbing on the flank, improving surface quality and lowering cutting temperatures. These geometry choices help maintain dimension and surface integrity during heavy engagement or when machining difficult batches, increasing overall process reliability.

Versatile form factor for integrated tool systems

The square 90° shape and size designation offer good indexing options and a stable seating in common holders. The T3 thickness and tolerance class M provide mechanical strength and consistent fit in pocketed tool bodies, making the insert suitable for both turning and approach‑boring operations where rigidity matters. Compatibility with common clamping systems allows straightforward integration into existing tooling setups, supporting efficient changeover and inventory management.

Shop‑floor benefits: productivity, predictability, and lower total cost

Using a coated, application‑focused grade minimises unexpected interruptions and supports higher cutting parameters where material and machine permit. The insert reduces scrap risk when machining stainless steel and superalloys by promoting stable cutting action and improved surface finish, which conserves operator time and downstream processing. For production environments aiming for repeatable cycles and traceable tool life, this insert offers a clear route to enhanced throughput and cost effectiveness.

FAQ

What materials is this insert best suited to machine?
This insert is designed primarily for stainless steel and heat‑resistant superalloys or titanium; the WSM10S grade and Tiger·tec Silver coating support stable cutting in these groups.

Can the insert be used for both turning and boring operations?
Yes, the SCMT09T308‑RM4 geometry and square 90° form permit use in turning and approach‑boring tool holders where the seat and clamping match the insert specification.

How does the RM4 chipbreaker improve machining?
The RM4 chipbreaker promotes controlled chip formation and evacuation, reducing the risk of built‑up edge and supporting consistent surface finish during intermittent or continuous cuts.
