CPMT060204-FM4 WMP20S — indexable turning insert with Tiger‑tec Silver coating (Walter Tools)

The CPMT060204‑FM4 WMP20S is an indexable turning insert developed for reliable machining of stainless steel in medium to robust cutting conditions, combining a proven chipbreaker with a compact Rhombus 80° geometry.

• Tiger‑tec Silver coating for process security
• WMP20S grade for stainless steel machining
• FM4 chipbreaker for consistent chip control
• 11° clearance and 0.4 mm corner radius

Stable chip control that keeps production running

The combination of the FM4 chipbreaker with a coated carbide grade provides predictable chip formation even when machining tough, ductile alloys. This geometry reduces the risk of built‑up edge and frequent interruption, which results in fewer tool changes and more predictable cycle times. The Tiger‑tec Silver coating contributes to heat resistance and lower friction at the cutting edge, thereby promoting a stable cutting zone and extended service intervals for the insert.

Designed for stainless steel and demanding turning tasks

The insert grade WMP20S is tuned for stainless steel applications and moderate to heavy duty operations. Its coating and substrate are balanced to resist thermal softening and to maintain a robust cutting edge under the typical high temperatures and work‑hardening tendencies of austenitic steels. This makes the product suitable for operations where consistent surface quality and tool life are necessary to meet production targets.

Geometry and edge preparation for precise, repeatable results

The compact Rhombus 80° shape and the specified 11° clearance angle combine to offer good approach angles and reliable seat stability in standard toolholders. The 0.4 mm corner radius supports a favourable edge strength while still allowing controlled material removal for finishing passes. The insert’s form and thickness code deliver rigidity and predictable engagement, which helps to reduce vibration and to secure repeatable dimensional accuracy in serial turning.

FAQ

What materials is this insert suited for?

The CPMT060204‑FM4 WMP20S is optimised for stainless steel machining; the WMP20S grade and Tiger‑tec Silver coating support secure chip formation and edge stability when working with austenitic and other stainless grades.

How does the FM4 chipbreaker influence performance?

The FM4 chipbreaker promotes consistent, segmented chips that are easier to evacuate from the cutting zone, improving process reliability and reducing the risk of built‑up edge during longer cuts.

What benefits does the Tiger‑tec Silver coating provide?

The Tiger‑tec Silver coating reduces friction and improves thermal resistance at the cutting edge, helping to extend insert life and maintain surface quality under higher temperatures typical for stainless steel turning.

Which edge geometry should be expected for finishing or roughing?

This insert offers a 0.4 mm corner radius and a 11° clearance angle, which balance edge strength and surface finish; the Rhombus 80° form allows flexible approach angles for both finishing and medium stock removal.
