CNMG160612-MM5 WMP20S — Indexable turning insert (Tiger·tec Silver) by Walter Tools

The CNMG160612-MM5 WMP20S is an indexable turning insert designed for medium to robust machining of rostfreien Stahl, offering a rhombic 80° geometry and a 1.2 mm corner radius for stable edge life.

• Tiger·tec Silver coating for stable edges
• Optimised MM5 chipbreaker for secure chip control
• Rhombic 80° geometry for versatile turning
• 0° negative rake for robust cuts
• Corner radius 1.2 mm for improved strength

Consistent performance for rostfreien Stahl machining

The combination of the WMP20S grade and the Tiger·tec Silver technology is engineered to manage the specific challenges of rostfreien Stahl, where toughness and built-up edge tendencies demand reliable heat and chip management. The coated carbide substrate promotes a stable cutting edge under elevated temperatures, resulting in predictable tool life and fewer interruptions to production. This performance translates into reduced downtimes and more consistent component quality when turning shafts, sleeves or complex rotational parts in corrosive-resistant alloys.

Coating and grade that extend cutting life

The Tiger·tec Silver series employs a multi-layer coating system that improves wear resistance and reduces friction at the cutting zone. In practice, this means the insert resists flank wear and preserves edge geometry for longer intervals between indexings. The WMP20S grade is optimised for rostfreien Stahl, balancing toughness and hardness to avoid premature chipping while maintaining a sharp cutting edge—benefits that yield lower tooling consumption and more predictable process windows in serial production.

Geometry tailored for reliable machining and chip control

The rhombic 80° form with a 0° negative rake provides secure engagement in heavy or interrupted cuts and enhances edge robustness where mechanical stability is critical. The MM5 chipbreaker is tuned to produce short, controllable chips in common stainless-steel machining parameters, easing evacuation in both wet and dry conditions. A corner radius of 1.2 mm increases resistance to edge fracture, allowing slightly more aggressive feeds without sacrificing surface integrity or repeatability.

Productivity advantages and process security

Adopting this insert supports a balance of cutting performance and operational economy: optimised chip formation reduces machine stoppages, and the coated grade promotes longer tool life—both factors contributing to lower overall machining costs. Walter Tools’ focus on stable edge geometry and reproducible results helps to maintain consistent dimensional accuracy and surface finish across batches. For facilities aiming to improve cycle times while keeping scrap and rework to a minimum, this insert offers a practical route to greater throughput and enhanced process reliability.

FAQ

Which materials is this insert suitable for?
The CNMG160612-MM5 WMP20S from Walter Tools is specifically developed for rostfreien Stahl and performs well under medium to robust machining conditions.

What does the Tiger·tec Silver designation mean?
Tiger·tec Silver denotes a multi-layer coating technology combined with a coated carbide substrate that enhances wear resistance and reduces friction at the cutting edge, improving tool life in demanding applications.

How does the MM5 chipbreaker affect machining?
The MM5 chipbreaker creates short, controlled chips suited to stainless-steel turning, aiding evacuation and reducing the risk of entanglement or surface damage.

Is the 0° negative rake suitable for interrupted cuts?
Yes, the 0° negative rake increases mechanical edge strength and is advantageous for interrupted or robust cutting conditions where stability is essential.

What is the corner radius and why is it important?
The insert has a corner radius of 1.2 mm, which improves edge strength and allows for slightly higher feed rates without compromising surface finish or repeatability.
