SCMT09T308-E47 WSM30S — drill/boring indexable insert, Tiger·tec Silver, Walter Tools

The SCMT09T308-E47 WSM30S is a square 90° indexable insert engineered for drilling and boring operations in stainless steels and heat‑resistant superalloys, combining a wear‑resistant coating with an optimised chipbreaker for consistent metal removal.

• Tiger·tec Silver coating for wear resistance
• Optimised E47 chipbreaker for reliable chips
• 0.8 mm corner radius for strong cutting edge
• Suitable for stainless steels and superalloys

Proven process security when machining stainless and superalloys

The Tiger·tec Silver grade delivers consistent wear resistance and temperature tolerance, which is crucial when working with ISO group M (stainless steels) and S (superalloys and titanium). The coated cemented carbide grade supports stable cutting edges during interrupted cuts and high thermal loads, reducing the frequency of tool changes and improving overall machine uptime. Clear, repeatable behaviour under load translates into fewer production stops and a more predictable cost per part.

Stable chip formation and surface quality through engineered geometry

The E47 chipbreaker has been developed to control long, stringy chips that are typical in austenitic stainless steels. By promoting defined chip segmentation and evacuation, the chipbreaker reduces the risk of built‑up edge and improves surface finish on bore and drill exits. Combined with a 7° clearance angle, the geometry lowers friction and helps maintain dimensional accuracy over a longer tool life, so the machining process stays both efficient and reliable.

Robust edge strength for demanding operations

A 0.8 mm corner radius increases edge stability during plunge and radial cutting, offering a balance between strength and cutting precision. This radius helps absorb impact loads and resists micro‑chipping when encountering hard inclusions or workpiece variability. The square 90° insert form provides four usable cutting edges per insert, enabling economical edge usage and quick index changes to sustain cycle times in production environments.

Application guidance and selection advice for process optimisation

For bore and reaming tasks in tougher materials, selecting the WSM30S grade ensures thermal stability and controlled wear. The insert thickness T3 and size 09 suit medium‑duty drill/boring holders where rigidity and chip control matter. When setting cutting parameters, favour slightly reduced cutting speeds and increased feed per tooth for stainless steels to avoid work hardening; for superalloys, focus on maintaining coolant or appropriate lubrication to manage heat. Correct holder clamping and stable workholding complete the process chain for predictable results.
