CCMT060208-RM4 WSM20S – indexable turning insert, Tiger‑tec Silver, 7° relief | Walter Tools

The CCMT060208-RM4 WSM20S is an indexable turning insert optimised for heavy‑duty machining of rostfreier Stahl and heat‑resistant alloys in production environments

• Tiger‑tec Silver coated carbide grade WSM20S
• Designed for rostfreier Stahl and heat‑resistant alloys
• Rhombic 80° geometry with 0.8 mm corner radius
• RM4 chipbreaker for secure chip formation

Higher productivity when machining difficult materials

The coated carbide grade WSM20S from the Tiger‑tec Silver series is formulated to deliver stable cutting edges and reduced flank wear when machining demanding materials. Because the grade is optimised for the ISO groups M and S, the insert supports secure chip formation and thermal resilience during prolonged cuts in rostfreier Stahl and heat‑resistant superalloys. The result is an increase in process reliability and fewer tool changes, which translates directly to improved cycle times and predictable output in batch production.

Coating and grade engineered for longer life

A modern multilayer coating is combined with a wear‑resistant substrate to provide resistance against abrasive and adhesive wear mechanisms. The Tiger‑tec Silver technology reduces friction at the cutting zone and helps to maintain a consistent cutting edge, which enables higher cutting speeds and longer tool life compared with uncoated grades. This combination is particularly beneficial in operations where heat generation and built‑up edge are common, as the coating supports quicker heat dissipation and smoother chip evacuation.

Geometry and chip control that stabilise the process

The Rhombic 80° insert form, paired with a 0.8 mm corner radius and the RM4 chipbreaker, provides a balance between strength and precision. The 80° approach angle gives robust cutting edge engagement for interrupted or general turning, while the moderate corner radius enhances edge strength without compromising dimensional control. The RM4 chipbreaker is designed to produce manageable chip segments under varying depths of cut, which contributes to safer handling and reduced risk of chip tangling in automated setups.

Practical application and integration into production

The insert is specified as CCMT060208‑RM4 and is supplied in the Tiger‑tec Silver series, making it suitable for a wide range of turning operations where rostfreier Stahl and titanium alloys impose thermal and mechanical challenges. Integration into standard indexable holder systems is straightforward; the geometry supports both roughing passes where edge stability is critical and finishing passes where surface quality matters. Process windows should be validated on the component material, and cutting parameters can be adjusted to balance life and productivity for a given setup.

FAQ

What materials is this insert suitable for?
The CCMT060208‑RM4 WSM20S from Walter Tools is designed primarily for rostfreier Stahl and heat‑resistant superalloys; the WSM20S grade targets ISO groups M and S.

How does the Tiger‑tec Silver coating benefit cutting performance?
The Tiger‑tec Silver coating on the WSM20S grade reduces friction and improves heat resistance, which helps to extend tool life and maintain consistent cutting edges during machining.

Which geometry aspects improve process stability?
The rhombic 80° form combined with a 0.8 mm corner radius and the RM4 chipbreaker enhances edge strength and produces controlled chip shapes, resulting in a more stable machining process.

Is this insert suitable for finishing as well as roughing?
Yes, the CCMT060208‑RM4 WSM20S can be used for both roughing and finishing. The geometry offers sufficient robustness for heavier cuts while supporting acceptable surface quality on finishing passes.

How is chip control handled with this insert?
Chip formation is managed by the RM4 chipbreaker and the coated grade, which together encourage segmented chips and reduce the occurrence of long, tangled swarf in most turning operations.
