CCMT060204-MM4 WMP20S indexable insert for turning and drilling by Walter Tools — Tiger·tec Silver, optimised for stainless steel

CCMT060204-MM4 WMP20S is a rhombic 80° indexable insert designed for turning and bore-milling tasks in stainless steels and similar demanding materials

• Tiger·tec Silver coating for improved wear resistance
• Optimised for machining stainless steel (ISO group M)
• Rhombic 80° form with 0.4 mm nose radius
• MM4 chipbreaker for stable chip control

Consistent performance on stainless steels with a high-performance grade

The Walter WMP20S grade, based on the Tiger·tec Silver technology, is a coated carbide designed specifically for machining stainless steel (ISO group M). The combination of a modern coating and substrate composition reduces edge wear under adhesive and heat-intensive cutting conditions. As a result, operators benefit from stable chip formation and improved process reliability, which in turn reduces the need for frequent tool changes and supports longer uninterrupted production runs. The technical focus on adhesion resistance and thermal stability makes this grade suitable for medium to heavy-duty turning operations where workpiece material tends to work-harden.

Geometry and chip control that improve surface quality and repeatability

The insert’s rhombic 80° form and a 0.4 mm nose radius provide a balance between robust cutting edge and acceptable surface finish for general turning and finishing passes. The 7° relief angle helps to reduce contact on the flank face, and the MM4 chipbreaker is engineered to produce predictable, controlled chips when cutting ductile and sticky stainless alloys. This geometry supports repeatable dimensions and consistent surface quality, particularly on long runs where tool behaviour must remain uniform. The insert’s design also simplifies tool selection for versatile turning applications.

Productivity gains and process security in series production

Using Walter Tools grade inserts like this model contributes to measurable productivity improvements: fewer interruptions for insert changes, reduced scrap from unstable cutting, and consistent part quality. The coated grade and chip control also help to protect the cutting edge during transient conditions, giving greater margin against built-up edge. In production environments where reproducibility and tool life matter, the insert supports stable cycle times and better overall equipment effectiveness.

FAQ

Which materials is this insert intended for?
The CCMT060204-MM4 WMP20S is formulated for stainless steel (ISO group M); the Tiger·tec Silver coating and WMP20S grade support secure chip formation and reduced adhesive wear when machining such alloys.

What advantages does the MM4 chipbreaker provide?
The MM4 chipbreaker on this insert promotes controlled chip breaking and evacuation during turning, which improves process stability and reduces the risk of chip-related surface defects when using the CCMT060204-MM4 WMP20S insert.

How does the rhombic 80° form affect cutting performance?
The rhombic 80° geometry offers a robust cutting edge suitable for a range of turning operations; combined with a 0.4 mm nose radius it balances strength and surface finish, aiding dimensional consistency across production runs.

Is the grade suitable for medium to heavy-duty operations?
Yes. The WMP20S grade is intended for medium to robust cutting conditions in stainless steels, delivering good edge life and process reliability under demanding workloads.
