CNMM160612-HU5 WMP20S — Walter Tools indexable turning insert, Tiger·tec Silver for stainless steel

The CNMM160612-HU5 WMP20S is an indexable turning insert designed for machining stainless steel under medium to robust conditions, offering a negative 0° rake and a geometry that balances strength with predictable chip formation.

• Tiger·tec Silver coating for long tool life
• HU5 chipbreaker for stable chip control
• For stainless steel (ISO M) machining
• Rhombic 80° form, 1.2 mm corner radius

Consistent process performance with advanced coating

The combination of the Tiger·tec Silver coating and the WMP20S grade delivers improved wear resistance and thermal stability, which translates into longer tool life and fewer changes at the machine. In practice this means fewer interruptions in production and a more predictable tool cycle. The coating supports secure chip formation when machining stainless steel, a material group known for toughness and heat sensitivity, reducing the risk of built-up edge and unexpected edge failure.

Geometry engineered to protect the cutting edge

The rhombic 80° shape with a corner radius 1.2 mm provides a robust edge that resists chipping during interrupted cuts and heavier engagement. The negative 0° rake increases edge stability for demanding turning applications, so the insert sustains higher radial loads without premature deformation. This geometry is particularly beneficial for operations where repeatable dimensional accuracy and surface integrity are required under moderate to heavy cutting conditions.

Chip control and machinability for stainless steel

The HU5 chipbreaker is tuned for reliable swarf formation with ductile materials; it encourages short, controllable chips that evacuate easily from the cutting zone. Together with the coated carbide grade, the insert reduces thermal and mechanical work on the cutting edge, improving overall process reliability. For shops aiming to enhance throughput, this combination supports consistent cycle times and steady surface quality when working with stainless steel.

Integration, handling and application guidance

The insert is compatible with standard CNMM toolholders and indexes in typical turning tool systems; the standard designation aligns with common toolholder references for straightforward integration. As an indexable insert, it allows quick corner changes to restore cutting geometry without regrinding, supporting efficient shop-floor practices. For selection advice or to verify holder fitment and corner usage strategies, Metav Werkzeuge can provide technical consultation and application recommendations.

FAQ

What materials is this insert best suited for?
The CNMM160612-HU5 WMP20S insert is designed primarily for stainless steel (ISO M), offering secure chip formation and edge stability in such applications.

How does the Tiger·tec Silver coating benefit machining?
Tiger·tec Silver on the WMP20S grade increases thermal resistance and wear performance, extending tool life and supporting consistent surface finish in demanding turns.

What role does the HU5 chipbreaker play?
The HU5 chipbreaker promotes short, manageable chips and stabilises swarf control, which helps maintain process reliability and reduces the risk of entanglement during turning.

Is the insert compatible with standard CNMM toolholders?
The insert follows the CNMM designation and is suitable for standard CNMM-compatible toolholders; toolholder specifics should be checked against the tool system in use.

Can the insert handle interrupted cuts or heavier engagements?
Yes—the rhombic 80° geometry and the 1.2 mm corner radius provide enhanced edge strength, making the insert suitable for interrupted cuts and more robust turning operations.
