CNMG160612-MU5 WMP20S indexable turning insert — Tiger‑tec Silver, for stainless steel (Walter Tools)

CNMG160612-MU5 WMP20S is an indexable turning insert from the Tiger‑tec Silver series designed for robust stainless steel machining under medium to demanding conditions.

Tiger‑tec Silver coated grade WMP20S
Optimised MU5 chipbreaker for stainless
Rhombic 80° geometry with 0° negative rake
Corner radius 1.2 mm for enhanced edge stability

Consistent productivity when machining stainless steel

The Tiger‑tec Silver WMP20S grade is engineered to address the typical challenges of stainless steel: high toughness, tendency to form built‑up edge and elevated cutting temperatures. With a coated carbide substrate and tailored surface treatment, the grade promotes stable wear behaviour and predictable tool life. Combined with the MU5 chipbreaker, the system encourages controlled chip formation, reducing interruptions from tangled chips and improving cycle‑time consistency — a direct contribution to higher throughput and lower rework rates.

Geometry that supports longer edge life and secure seating

The rhombic 80° insert shape with a corner radius of 1.2 mm and 0° negative rake delivers a balance of strength and accessibility in internal and external turning. The geometry distributes cutting forces over a larger edge area, which helps to avoid premature chipping during interrupted cuts or tougher stainless grades. The standard insert size (16 mm) and thickness code 06 ensure compatibility with common toolholders while the specific seat form improves repeatability at index changes, reducing setup time and scrap.

Predictable performance through optimised chip control

The MU5 chipbreaker is optimised for ductile materials like stainless steel, promoting short, manageable chips under a wide range of feeds and depths. This results in fewer machine stops and safer handling at higher cutting temperatures. The coated surface acts as a thermal barrier, lowering friction and improving dimensional stability during longer engagements. For production environments seeking reproducible surface finish and minimal operator intervention, this combination is a pragmatic choice that supports lean machining objectives.

Selection and application advice for reliable results

When integrating this insert into a turning process, match feed and depth parameters to the workpiece alloy and hardness, favouring moderate feeds to maintain chip control. The CNMG160612-MU5 WMP20S insert is particularly suitable for medium to robust cutting conditions in stainless steel, where the Tiger‑tec Silver coating and MU5 geometry together reduce the risk of built‑up edge. For complex part geometries or unusual alloys, consult Metav Werkzeuge for specific recommendations on toolholders and cutting data to ensure process security.
