WCMT06T308-E47 WSM20S indexable insert – Trigon 80°, 7° clearance | Walter Tools

WCMT06T308-E47 WSM20S is an indexable insert engineered for drilling and boring applications in demanding materials such as stainless steels and heat‑resistant superalloys

• Tiger·tec Silver coating for thermal stability
• Optimised E47 chipbreaker for secure chip flow
• Trigon 80° form with 0.8 mm corner radius
• Suitable for stainless steel and superalloys

Consistent edge life in high‑heat machining

The insert combines the WSM20S coated carbide grade with Tiger·tec Silver technology to deliver improved resistance against thermal loading and flank wear. This results in more stable cutting edges when machining tough alloys, which reduces unscheduled tool changes and increases productive cutting time. Coated carbide here means a ceramic or PVD/CVD finish applied to a hard substrate to slow wear and protect the cutting edge; the practical benefit is a longer useful life and fewer interruptions to the machining cycle.

Geometry designed to secure process reliability

The Trigon 80° plate form, paired with a 0.8 mm corner radius and 7° clearance, optimises contact conditions at the tool‑workpiece interface. The E47 chipbreaker is engineered for consistent chip formation and evacuation, lowering the risk of built‑up edge and improving surface finish. In practice, that means more predictable cycle times and reduced scrap rates, particularly in interrupted cuts and atypical chip‑producing profiles.

Suited for demanding materials and varied operations

Marked for ISO groups M and S, the insert is specified for stainless steels and heat‑resistant superalloys or titanium respectively. For these materials, heat generation and poor thermal conductivity are typical challenges; the WSM20S grade addresses them by combining hardness with thermal protection. The result is reliable chip control and repeatable performance in drilling and boring tasks where material behaviour can otherwise cause rapid edge degradation.

Compatibility, handling and economic benefit

The plate is produced to tolerance class M and the standard size designation ensures compatibility with common drilling/boring cutter bodies. The thickness T3 and the size 06 give a robust seating and minimise deformation under load. Using this insert typically leads to reduced tooling costs per component through longer life and fewer tool swaps, thereby improving overall machining economy without compromising surface quality or dimensional control. The combination of geometry and coating therefore supports higher uptime and predictable output.

FAQ

What materials is this insert designed for?
The WCMT06T308-E47 WSM20S insert is specified for ISO groups M and S, meaning it is suitable for stainless steels and heat‑resistant superalloys or titanium depending on machining conditions.

How does the Tiger·tec Silver technology benefit drilling and boring operations?
Tiger·tec Silver provides enhanced thermal resistance and wear protection for the coated carbide base, which in the WCMT06T308-E47 WSM20S leads to more stable cutting edges and longer tool life under high temperatures.

What role does the E47 chipbreaker play in performance?
The E47 chipbreaker controls chip formation and evacuation to prevent clogging and built‑up edge; on the WCMT06T308-E47 WSM20S this supports consistent surface finish and reduces the risk of interrupted‑cut failures.

Is the insert compatible with standard cutter bodies?
Yes, the insert is produced to common tolerances (class M) and size designation 06 with thickness T3, ensuring compatibility with matching indexable drill and boring bodies.
