SCMT09T308-E47 WSM20S — Drilling/boring indexable insert, Tiger·tec Silver, Walter Tools; 0.8 mm radius, 7° clearance

A SCMT09T308-E47 WSM20S indexable insert engineered for drilling and boring operations in stainless steel and high‑temperature alloys, providing stable chip control and consistent cutting performance.

• Tiger·tec Silver coating for high-temperature stability
• WSM20S grade for stainless steels and superalloys
• Square 90° shape with 0.8 mm corner radius
• 7° clearance angle for secure cutting-edge contact

Consistent performance in stainless steel and superalloys

The combination of the WSM20S grade with the Tiger·tec Silver coating targets the common challenges of machining stainless steel and heat‑resistant superalloys: high heat generation, work‑hardening and difficult chip formation. The coated cemented‑carbide substrate is tailored to support stable chip formation and to resist thermal and mechanical wear, resulting in fewer unscheduled tool changes and more predictable component quality. This reduces scrap rates and increases process reliability on serial production runs.

Geometry engineered for edge security and surface quality

A square 90° geometry paired with a 0.8 mm corner radius and a 7° clearance angle balances edge strength and surface finish. The corner radius increases the cutting‑edge robustness for plunge and axial cuts, while the moderate relief angle limits rubbing and heat build‑up. The fitted E47 chipbreaker is designed to promote controlled chip segmentation under typical drilling and boring feed conditions, helping to avoid built‑up edge and to sustain a consistent surface integrity on the workpiece.

Productivity gains through predictable tool life and straightforward handling

The insert’s dimensions and tolerances favour quick indexing and repeatable set‑up in compatible toolholders, supporting short changeover times and steady cycle times. As a coated, indexable solution, it offers an economical path to extended cutting life and fewer complete tool replacements. The result is improved uptime and lower cost‑per‑part in medium to high‑volume machining of demanding materials, with the added confidence of a brand‑grade design focused on process stability.

FAQ

Which materials is this insert intended for?
The SCMT09T308‑E47 WSM20S insert is designed primarily for stainless steel and for heat‑resistant superalloys and titanium, reflecting the WSM20S grade’s emphasis on thermal stability and secure chip formation.

What is the corner radius and how does it affect cutting?
The insert features a 0.8 mm corner radius; this radius strengthens the cutting edge for plunge and axial engagements and contributes to a consistent surface finish when machining demanding materials.

Which chipbreaker is fitted and what is its benefit?
This insert uses the E47 chipbreaker, which promotes controlled chip segmentation and reliable evacuation in drilling and boring operations, reducing the risk of built‑up edge.

How does the Tiger·tec Silver series support production?
The Tiger·tec Silver coating increases heat resistance and wear performance; paired with the WSM20S grade, it helps to extend tool life and maintain process stability over longer runs.

Is the insert compatible with standard toolholders for drilling and boring?
The SCMT09T308‑E47 insert conforms to common square 90° insert dimensions and tolerance class M, enabling straightforward indexing in compatible drilling and boring toolholders.
