CNMG120404-MM5 WMP20S Turning indexable insert, Rhombic 80°, Walter Tools

The CNMG120404-MM5 WMP20S is a turning insert engineered for machining stainless steels under medium to robust cutting conditions.

• Tiger·tec Silver coating
• Designed for stainless steels (ISO M)
• Rhombic 80° geometry
• MM5 chipbreaker for stable chips

Consistent cutting performance for stainless steel production

The coated carbide grade delivers a predictable trade-off between tool life and cutting reliability, particularly on stainless steels (ISO M) that are prone to work‑hardening and built‑up edge. The combination of the Tiger·tec Silver technology and the specified WMP20S grade supports a stable cutting edge under fluctuating conditions, which helps to reduce rework and unscheduled tool changes. This results in improved throughput and a more stable process capability in batch and continuous turning operations.

Geometry and chip control that minimise disruptions

The rhombic 80° insert form with a 0.4 mm nose radius and a 0° negative rake provides mechanical robustness and versatility between finishing and semi‑finishing cuts. The MM5 chipbreaker is optimised to promote reliable chip formation when machining tough, adhesive materials, reducing the risk of chip entanglement and machine stoppages. Fewer interruptions and better chip control translate into higher machine utilisation and lower indirect production costs.

Coating and grade advantages — why WMP20S pays off

The combination of the WMP20S coated carbide and the Tiger·tec Silver series offers enhanced oxidation resistance and edge stability at elevated cutting temperatures typical for stainless steel turning. This technical pairing supports longer periods between indexings and consistent surface quality, which can shorten downstream finishing steps.

FAQ

What materials is this insert intended for?
The CNMG120404-MM5 WMP20S insert is designed primarily for machining stainless steels (ISO M) and provides stable performance where adhesion and heat generation are critical factors.

How does the MM5 chipbreaker influence machining?
The MM5 chipbreaker promotes predictable chip formation and evacuation in demanding stainless steel cuts, reducing chip entanglement and improving process stability for the CNMG120404-MM5 WMP20S.

What benefits does the Tiger·tec Silver coating provide?
The Tiger·tec Silver coating enhances oxidation resistance and edge stability at raised temperatures, helping the WMP20S grade to maintain a consistent cutting edge and prolong usable life.

Which cutting conditions suit the rhombic 80° geometry best?
The rhombic 80° form with a 0.4 mm nose radius and 0° negative rake is well suited to mixed operations between finishing and semi‑finishing, where mechanical strength and predictable chip behaviour are required.
