WCMT030204-E47 WSM20S — Drilling/boring indexable insert, Tiger‑tec Silver, Trigon 80° (Walter Tools)

WCMT030204-E47 WSM20S is a Trigon 80° indexable insert designed for demanding drilling and bore‑enlarging operations in difficult‑to‑machine materials

• Tiger‑tec Silver coating for high wear resistance
• Optimised chipformer E47 for stable chip control
• Trigon 80° shape for deep drilling and bore enlarging
• Suitable for rostfreier Stahl and high‑temperature alloys

Longer tool life through coated carbide technology

The combination of the WSM20S grade and Tiger‑tec Silver coating focuses on thermal stability and abrasion resistance, which directly reduces flank and crater wear during interrupted drilling. The coated cemented carbide substrate supports consistent edge integrity, particularly when machining rostfreier Stahl or heat‑resistant alloys that tend to work‑harden and generate high temperatures. In practice, this means fewer tool changes and a steadier process window, which translates into improved uptime and predictable tool consumption for production environments.

Improved process reliability with geometry and chip control

A Trigon 80° plate form with a 0.4 mm corner radius and a 7° relief angle provides a balanced mix of strength and cutting engagement for bore enlargement. The E47 chipformer promotes controlled chip breaking even under tougher feeds and variable depths of cut, lowering the risk of build‑up or unstable chips that can compromise surface finish. For machining centres and drilling heads, this geometry contributes to repeatable hole quality and reduced rework, supporting tighter tolerances and better first‑pass yield.

Clear selection and machining guidance for workshop use

The ISO designation decodes as a compact indication of dimensions and function: the WCMT format denotes a Trigon insert in the 03 size with a plate thickness of 02. The WSM20S grade is tailored for demanding materials and is classified for use on S / M groups — heat‑resistant superalloys / titanium and rostfreier Stahl. When integrating these inserts into toolholders, attention to recommended feeds, speeds and cooling strategy will maximise performance; the coated grade permits elevated cutting parameters in many cases, but actual settings should follow machine and holder capability. For customers less familiar with insert geometry, the technical team at Metav Werkzeuge can provide mounting and process recommendations.

FAQ

What materials is the WCMT030204-E47 WSM20S insert suitable for?
The WCMT030204‑E47 WSM20S insert from Walter Tools is specified for group S and M materials, meaning heat‑resistant superalloys/titanium and rostfreier Stahl; the grade supports secure chip formation and edge stability in these applications.

How does the Trigon 80° geometry affect hole quality?
The Trigon 80° form concentrates cutting forces for deep drilling and bore enlarging while the 0.4 mm corner radius enhances edge strength, contributing to repeatable hole geometries and improved surface integrity when the insert is used in suitable holders.

What does the E47 chipformer provide in practice?
The E47 chipformer is designed for controlled chip breaking under varying feeds and interrupted cuts; in production this reduces chip‑related interruptions and helps maintain consistent tool life and surface finish.

Can the Tiger‑tec Silver coating be used at higher cutting speeds?
The Tiger‑tec Silver coating promotes thermal resistance and wear protection, enabling elevated cutting parameters on many machines; however, machining parameters should be adapted to machine rigidity and holder limitations.
