CPMT060204-FM4 WSM20S — Indexable insert for drilling/bore and turning, Tiger·tec Silver, FM4 chipbreaker — Walter Tools

The CPMT060204-FM4 WSM20S is a rhombic 80° indexable insert designed for productive machining of stainless steel and heat‑resistant superalloys in demanding turning and boring applications

• Tiger·tec Silver coating for thermal robustness
• WSM20S grade for stainless steel and superalloys
• FM4 chipbreaker for reliable chip control
• 0.4 mm corner radius for improved edge stability

Increased process efficiency through coating and grade selection

The combination of the Tiger·tec Silver coating with the WSM20S carbide grade is engineered to extend tool life under high temperatures and adhesive wear typical of stainless steel and nickel‑based alloys. The coating raises thermal resistance and reduces friction at the cutting edge, which in turn supports consistent cutting forces and extended productive time between index changes. For production environments seeking predictable cycle times, this insert reduces machining interruptions and contributes to a more economical throughput.

Predictable chip control and surface quality for stable operations

Equipped with the FM4 chipbreaker and a rhombic 80° geometry, the insert provides controlled chip formation and reliable evacuation, particularly in narrow grooves or interrupted cuts. The 0.4 mm corner radius increases edge strength and helps resist breakouts during heavier depths of cut, while the 11° clearance angle supports low rubbing and improved surface finish. These characteristics combine to lower the risk of built‑up edge and help achieve a consistent surface quality on components made from stainless steel and heat‑resistant materials.

Practical selection and application advice for workshop use

The insert’s designation and size code simplify toolholder matching and inventory management: the plate format and thickness codes are standardised for straightforward integration with common toolholders. The WSM20S grade is particularly suitable where secure chip formation and stable cutting edges are required; when tackling highly heat‑generating operations, this grade and the coating offer an advantageous balance between wear resistance and edge toughness. For setup, refer to toolholder manufacturer recommendations and adjust feeds and speeds conservatively when first testing a new batch.

FAQ

What materials is this insert suitable for?
The WSM20S grade with Tiger·tec Silver coating is intended primarily for stainless steel and heat‑resistant superalloys; the insert supports secure chip formation and thermal stability in these groups.

How does the FM4 chipbreaker affect machining?
The FM4 chipbreaker promotes short, controllable chips and reliable evacuation, which improves process stability when using the CPMT060204-FM4 WSM20S insert in turning and boring operations.

What is the benefit of the 0.4 mm corner radius?
A 0.4 mm corner radius increases edge strength and reduces the likelihood of chipping during heavier cuts, contributing to longer edge life and steadier surface quality.

Which toolholders match the rhombic 80° form?
Rhombic 80° inserts fit toolholders designed for CPMT‑type geometries; confirm the holder is specified for a CPMT060204 form and the corresponding thickness code before assembly.
