CNMG120412‑MM5 WMP20S – Indexable turning insert, Tiger‑tec Silver (Walter Tools)

The CNMG120412‑MM5 WMP20S is an indexable turning insert designed for machining rostfreier Stahl in medium to robust cutting conditions, combining a durable coated grade with reliable chip control.

• Tiger‑tec Silver coating for long tool life
• WMP20S grade optimised for rostfreier Stahl
• Rhombic 80° geometry for universal turning
• Negative 0° rake with 1.2 mm corner radius

Increased cutting reliability for rostfreier Stahl

The Tiger‑tec Silver technology delivers a coated carbide grade that balances wear resistance with edge stability under demanding conditions. For materials classified as M (rostfreier Stahl) the combination of a dedicated grade and a tailored chipbreaker results in stable chip formation and reduced tendency to build up on the cutting edge. This reliability translates into fewer unscheduled tool changes and a more predictable production rhythm, improving throughput without sacrificing surface quality.

Geometry and chip control that reduce cycle times

A rhombic 80° form paired with the MM5 chipbreaker offers versatile approach angles for varied turning operations. The negative 0° rake increases robustness at the cutting edge, while the 1.2 mm corner radius smooths transitions and supports consistent dimensional stability. Together, these features help maintain cutting performance under moderate to heavy engagement, reducing the risk of edge chipping and contributing to more consistent cycle times.

Practical application guidance for safe integration

Marked for machining rostfreier Stahl according to ISO group M, the insert fits standard CNMG pockets and is suitable where stable edge life and controlled chips are priorities. The coated grade is targeted at mid to robust applications, so it is a pragmatic choice for mixed‑batch environments where operators require a single reliable grade across differing stainless alloys. When changing from uncoated or general‑purpose grades, expect improved surface finish and longer intervals between indexing.

Cost‑effectiveness through predictable performance

By reducing rework and limiting unexpected tool failures, a coated grade from the Tiger‑tec Silver series supports a leaner process. The engineered chip control and robust geometry contribute to consistent edge life, which in practice lowers tooling consumption and machine downtime. For workshops seeking to combine productivity with dependable results, this insert represents a focused investment in process stability and component quality.

FAQ

What materials is this insert designed for?
The CNMG120412‑MM5 WMP20S from Walter Tools is specified for rostfreier Stahl (ISO group M) and is formulated to improve chip control and edge life in such materials.

How does the MM5 chipbreaker affect machining?
The MM5 chipbreaker promotes stable chip formation and reliable evacuation, which helps to avoid built‑up edge and maintain a consistent surface finish when machining rostfreier Stahl.

Is the insert suitable for heavy‑duty turning?
The negative 0° rake and robust geometry make the insert appropriate for medium to robust cutting conditions; it offers increased resistance to edge chipping compared with more positive geometries.

Which series and grade does this insert belong to?
This insert is part of the Tiger‑tec Silver series and uses the WMP20S grade, a coated carbide composition optimised for the challenges of rostfreier Stahl.

Can the insert be used in standard CNMG toolholders?
The CNMG120412‑MM5 designation corresponds to standard CNMG pockets; compatibility depends on holder specifications, but the form is designed for common CNMG toolholders.
