CPMT060204-MM4 WSM20S – indexable turning insert, Tiger·tec Silver coating, for stainless steel and superalloys | Walter Tools

The CPMT060204-MM4 WSM20S is a rhombic 80° indexable turning insert with Tiger·tec Silver coating, designed for secure cutting in stainless steel and heat-resistant superalloys.

• Tiger·tec Silver coating for long tool life
• MM4 chipbreaker for stable chip control
• Rhombic 80° form with 11° free angle
• Optimised for stainless steel and superalloys

Longer tool life through advanced coating technology

The combination of the Tiger·tec Silver platform and the WSM20S grade delivers enhanced wear resistance and thermal stability in continuous and interrupted cuts. The multilayer coated carbide resists adhesion and flank wear, which reduces the frequency of tool changes and supports consistent cycle times. For workshops machining stainless steel or other demanding materials, this translates into predictable tool life and fewer process interruptions, increasing overall productivity.

Consistent chip control and improved surface quality

The MM4 chipbreaker geometry is engineered to produce manageable chips across a range of cutting depths, contributing to safer chip evacuation and a more reliable process. The rhombic 80° insert form combined with a 0.4 mm corner radius supports a good balance between edge strength and surface finish, enabling stable passes and reduced rework. Clear explanation: a chipbreaker shapes the chips to prevent long, entangling swarf and to lower heat concentration at the cutting edge.

Suited to high-demand materials and difficult-to-machine alloys

This insert grade is tuned for the challenges of machining materials in the ISO groups M and S: stainless steel (austenitic and other stainless grades) and heat-resistant superalloys or titanium, which generate high temperatures and strain the cutting edge. The coating and grade chemistry aim to maintain edge integrity under thermal load, supporting secure cutting even where built-up edge or rapid wear would otherwise occur. The result is greater process security and consistent tolerances in serial production.

Process recommendations for reliable results

The 11° free angle and tolerance class M help to reduce flank rubbing while maintaining cutting stability; the insert execution T supports standard clamping systems. For best results, ensure a rigid toolholder and appropriate coolant strategy to manage temperatures when machining stainless steel or superalloys. The insert’s geometry and chip control are particularly beneficial for semi-finishing and finishing operations where surface quality and repeatability matter most.

FAQ

What materials is this insert suitable for?
The CPMT060204-MM4 WSM20S insert is suitable for stainless steel and heat-resistant superalloys (ISO groups M and S), with the WSM20S grade optimised for thermal stability and reliable chip control.

How does the MM4 chipbreaker affect machining?
The MM4 chipbreaker on the CPMT060204-MM4 promotes short, controllable chips and reduces the risk of long swarf, improving safety and surface quality during turning.

What does the 0.4 mm corner radius mean for finishing?
A 0.4 mm corner radius provides a compromise between edge strength and surface finish: it supports fine finishes while maintaining robustness against edge chipping in interrupted cuts.

Which coating technology is applied to this insert?
The insert uses the Tiger·tec Silver coating system; this multilayer coating enhances wear resistance and reduces adhesion on the cutting edge during operations in stainless steel and similar alloys.
