SCMT060204-E47 WSM20S drilling/reaming indexable insert (for stainless steel & superalloys) — Walter Tools

The SCMT060204-E47 WSM20S is a square 90° indexable insert engineered for drilling and reaming applications, optimised for rostfreiem Stahl and heat‑resistant superalloys in high‑demand industrial machining.

*Tiger·tec Silver coating for high-temp performance
*Designed for stainless steels and superalloys
*Square 90° insert with 0.4 mm corner radius
*7° relief angle for secure chip control

High‑temperature performance and reliable chip control

The insert uses the Tiger·tec Silver coating combined with the WSM20S grade to deliver enhanced thermal stability and wear resistance when machining rostfreiem Stahl and heat‑resistant alloys. This combination supports stable chip formation and a secure cutting edge under elevated temperatures, reducing the frequency of tool changes and keeping cycle times predictable. The integrated E47 chipbreaker promotes controlled chips in interrupted or continuous drilling and reaming passes, which helps prevent built‑up edge and enhances process reliability even in challenging materials.

Geometry designed for edge strength and dimensional stability

A square 90° plate form with a 0.4 mm corner radius and a 7° relief angle creates a robust cutting geometry that balances edge strength with heat evacuation. The modest corner radius increases resistance to chipping while preserving the ability to achieve accurate hole profiles, and the relief geometry supports repeatable seating in the toolholder. These characteristics translate into consistent hole quality and fewer rejects in series production, particularly where hole tolerances and surface finish matter.

Productivity gains and predictable tool life

The coated, grade‑specific construction focuses on long effective life and reduced downtime. The combination of coating and substrate chemistry improves wear resistance and maintains a sharp cutting line over extended runs, which contributes directly to higher uptime and lower per‑part tooling costs. Process engineers benefit from the predictable wear behaviour: once cutting parameters are optimised for the insert and the workpiece group, machining can proceed with fewer interruptions and more consistent output.

Application scope and practical recommendations

This insert is intended for use in drilling and reaming tool bodies and is suitable for workpiece groups M (rostfreie Stähle) and S (heat‑resistant superalloys and titanium) as defined in ISO 513. The design supports both continuous and interrupted machining where thermal loads are high. For best results, match the insert geometry and chipbreaker to the toolbody and machining strategy, adjust cutting speeds to the grade’s recommendations and verify coolant strategy where applicable. For complex assemblies or unusual alloys, a short feasibility check is advisable before large runs.

FAQ

What materials is this insert suitable for?
The SCMT060204-E47 WSM20S insert is designed for rostfreie Stähle (ISO group M) and heat‑resistant superalloys or titanium (ISO group S), offering secure chip formation and edge stability in these materials.

Which chipbreaker does the insert use and why is it important?
This insert features the E47 chipbreaker; it controls chip flow during drilling and reaming to reduce built‑up edge and improve hole quality, especially in rostfreiem Stahl and difficult alloys.

How does the Tiger·tec Silver series benefit holemaking operations?
Tiger·tec Silver provides enhanced thermal resistance and wear protection, leading to longer tool life, fewer interruptions and more consistent surface finishes in high‑temperature drilling and reaming.

Is this insert compatible with standard drilling tool bodies?
The geometry (square 90°) and designation match common indexable insert tool systems for drilling/reaming; toolbody compatibility should be verified against the SCMT060204-E47 seat and clamping specifications.

What cutting data adjustments are recommended for stainless steels?
Due to the toughness and heat generation of rostfreie Stähle, moderate cutting speeds with controlled feed and effective chip evacuation are recommended; consult Metav Werkzeuge or technical datasheets for precise parameters.
