CCMT120404-E47 WSM20S Drilling/Boring indexable insert – Rhombus 80°, Tiger‑tec Silver (Walter Tools)

The CCMT120404-E47 WSM20S is a rhombic 80° indexable insert engineered for drilling and bore‑enlargement tasks in stainless steels and heat‑resistant superalloys.

• Tiger‑tec Silver coating for enhanced wear resistance
• WSM20S grade optimised for stainless steel and superalloys
• Rhombic 80° form with 0.4 mm corner radius
• 7° clearance and stable E47 chipbreaker geometry

Greater process reliability for difficult‑to‑machine alloys

The combination of the Tiger‑tec Silver coating and the WSM20S carbide grade delivers consistent wear resistance and a predictable edge life when machining materials that generate high temperatures and tend to work‑harden. This specification supports secure chip formation and reduces the frequency of tool changes, which improves uptime in batch and continuous operations. The description focuses on measurable process benefits and is intended for engineering and production planners seeking dependable cutting performance.

Geometry and chip control for reproducible bore quality

The rhombic 80° insert form, together with the E47 chipbreaker and a 0.4 mm corner radius, is designed to provide stable cutting forces and controlled chip breaking during drilling and boring operations. The moderate corner radius balances edge strength and finishing capability, while the dedicated chipbreaker geometry aids evacuation and reduces the risk of built‑up edge on the cutting face. These geometric choices promote repeatable dimensional results and help maintain surface quality across series production.

Cost‑effective productivity through material‑specific design

Optimised for machining stainless steels (M) and heat‑resistant superalloys/titanium (S), the insert supports higher process security in challenging applications by combining a robust coating technology with a tool grade selected for thermal and mechanical stability. The result is a lower overall cost per hole thanks to fewer interruptions, predictable tool life and easier process parameter stabilisation. The technical design therefore contributes directly to improved line efficiency and reduced scrap rates.

Practical handling and integration into existing tool systems

The insert matches industry standard clamping systems for its geometry, enabling straightforward replacement and minimal retrofit effort. For best results, pair the insert with a stable drill or boring head and ensure proper seat clamping to maintain the intended relief angle of 7°. While specific cutting data depends on the machine and workpiece, the insert’s construction supports coolant and dry operations where appropriate and benefits from process monitoring to fine‑tune feeds and speeds for each workpiece alloy.

FAQ

What materials is this insert suitable for?
The WSM20S grade insert is suited for stainless steels (M) and heat‑resistant superalloys/titanium (S), offering enhanced edge stability for these demanding materials.

How does the Tiger‑tec Silver coating benefit production?
The Tiger‑tec Silver coating increases wear resistance and thermal stability, which for the CCMT120404‑E47 WSM20S insert leads to longer life and more consistent performance in high‑temperature cutting.

Which chipbreaker is fitted to this insert and what does it do?
The insert uses an E47 chipbreaker, which controls chip formation and evacuation to reduce build‑up and promote stable cutting during drilling and boring operations.

Is the geometry compatible with standard tool holders?
Yes, the rhombic 80° form and standard size coding allow integration into common drilling and boring tool bodies that accept CCMT‑style indexable inserts.

Can this insert be used for finishing operations?
With its 0.4 mm corner radius and stable edge design, the insert can achieve good surface quality; final finishing suitability depends on the specific alloy and machine stability.
