WCMT040204-E47 WSM20S — Drilling/boring indexable insert, Tiger·tec Silver, for stainless steels & superalloys — Walter Tools

WCMT040204-E47 WSM20S is a Trigon 80° indexable insert designed for drilling and boring operations in demanding materials such as stainless steels and heat‑resistant superalloys

• Tiger·tec Silver coating for high thermal resistance
• WSM20S grade optimised for stainless steel and superalloys
• Trigon 80° form with 0.4 mm corner radius
• 7° clearance angle for secure chip control

High-temperature performance for demanding materials

The combination of the Tiger·tec Silver coating and the WSM20S grade provides a robust solution for materials that generate heat and strain the cutting edge. Coated carbide technology increases wear resistance and helps maintain a stable cutting edge when machining stainless steels and superalloys, which are known for poor thermal conductivity and rapid tool loading. This results in fewer interruptions, more predictable tool life and a measurable improvement in process stability for production environments.

Precision geometry that stabilises chip flow and surface finish

The Trigon 80° insert geometry, together with the E47 chipbreaker and a 0.4 mm corner radius, balances edge strength and chip control. The insert shape reduces vibration during drilling and boring, while the chipbreaker guides swarf away from the cutting zone. As a result, the machining process benefits from improved surface integrity and fewer rework cycles, which supports higher first‑pass yields and steadier cycle times on the shop floor.

Practical advantages in toolpath consistency and setup

A 7° clearance angle and clear dimensional codes (insert size 04, thickness code 02) ensure compatibility with common toolholder systems used in drilling and boring applications. The tolerance class M underlines consistent manufacturing precision, helping to maintain reproducible cutting conditions across batches. These characteristics contribute to reduced setup times and consistent tool performance, which is particularly valuable in high‑mix or repeat production scenarios.

Production reliability and economical operation

Designed for the challenges of machining tough materials, this coated carbide insert supports stable chip formation and reliable edge life, contributing to lower downtime and less frequent insert changes. The technical concept behind the insert focuses on process security and predictable productivity—factors that influence total cost of ownership beyond the unit price. The brand reputation of Walter Tools further supports confidence in repeatable results and supply chain reliability.
