TCMT16T308-FM4 WMP20S – Turning and drilling insert, Tiger‑tec Silver, for rostfreier Stahl | Walter Tools

The TCMT16T308-FM4 WMP20S is a triangular 60° indexable insert designed for turning and light boring operations, offering a coated cemented‑carbide grade optimised for rostfreier Stahl and medium to heavy duty use.

• Tiger‑tec Silver grade WMP20S
• Triangular 60° form for stable seating
• FM4 chipbreaker for secure chip control
• 0.8 mm corner radius for robust edges

Increased process stability where it matters

The combination of the WMP20S grade and Tiger‑tec Silver coating delivers balanced wear resistance and thermal stability specifically for rostfreier Stahl machining. The coated cemented‑carbide composition supports a predictable cutting edge under the heat and work‑hardening typical of austenitic stainless steels. The FM4 chipbreaker actively shapes chips to reduce entanglement and vibration, which helps maintain surface finish and lowers the risk of built‑up edge. By selecting this insert, workshops gain a measurable improvement in cycle consistency and fewer unplanned interventions during serial turning.

Geometry that reduces tool changes and downtime

A triangle 60° form and a 0.8 mm corner radius provide a robust cutting edge that tolerates occasional interrupted cuts and offers good load distribution. The insert’s 7° clearance angle reduces rubbing on flank faces while keeping cutting forces manageable; the nominal 16 mm inscribed circle and T3 thickness ensure secure clamping in standard toolholders. These geometric choices mean fewer indexings and a more economical use of each insert, so set‑ups remain stable and predictable. For operations where repeatability matters, the engineered geometry contributes directly to shorter non‑productive time.

Practical application and machining guidance

The FM4 chipbreaker and the WMP20S composition are intended for rostfreier Stahl where chip control and edge robustness are priorities. In practice, start with moderate cutting speeds and increased coolant flow when machining heat‑sensitive alloys; the coated grade tolerates elevated temperatures but benefits from consistent cooling. The insert is suitable for both conventional and high‑volume turning cells where stable edge life and reproducible results are required. Walter Tools’ production standards and the Tiger‑tec Silver technology together support efficient metal removal with an emphasis on steady process windows and achievable surface qualities.

FAQ

What materials is this insert intended for?
The TCMT16T308-FM4 WMP20S insert is designed primarily for rostfreier Stahl; the WMP20S grade and Tiger‑tec Silver coating support secure chip formation in stainless applications.

Can the insert be used for both turning and boring?
Yes, this indexable insert is suitable for turning and light drilling/boring operations when mounted in the appropriate Walter Tools toolholder.

How does the FM4 chipbreaker help in machining?
The FM4 chipbreaker on the TCMT16T308-FM4 WMP20S shapes and controls chips to reduce entanglement and vibration, improving surface finish and tool life in rostfreier Stahl cutting.

What is the benefit of the 0.8 mm corner radius?
A 0.8 mm corner radius offers a compromise between edge strength and profile fidelity, giving the insert robustness for interrupted cuts while maintaining good form accuracy.

Is this insert compatible with standard TCMT toolholders?
The TCMT designation indicates compatibility with standard TCMT toolholder pockets; ensure correct clamping torque and seat condition for optimal performance.
