CNMG120404-FM5 CNMG120404-FM5 WMP20G indexable insert — for stainless steels | Walter Tools

CNMG120404-FM5 WMP20G is a rhombic 80° turning insert designed for machining stainless steels in medium to robust conditions

• Tiger·tec Gold coating for long tool life
• Optimised chip control FM5 chipbreaker
• Rhombic 80° form with 0.4 mm nose radius
• Suited for stainless steels (ISO M)

High-performance cutting for stainless steels

The insert is engineered to deliver stable performance when machining stainless steels, where material toughness and heat generation demand robust solutions. The combination of the WMP20G carbide grade and Tiger·tec Gold coating provides improved wear resistance and heat protection, reducing the risk of edge build-up and premature failure. With its negative rake and consistent substrate quality, the geometry permits reliable cutting in interrupted cuts and higher feed conditions, supporting a steady production flow and predictable tool life.

Precise chip control and consistent surface quality

An optimised FM5 chipbreaker promotes controlled chip formation and evacuation, which reduces built-up edge and improves surface finish on challenging alloys. The insert’s chip control characteristics lower the likelihood of entanglement and tool-induced marking, enabling more consistent part quality and fewer rework cycles. This results in measurable gains in process stability and reduces downtime caused by frequent insert changes or manual chip handling.

Geometry that supports repeatability and versatile setups

The rhombic 80° form with a 0.4 mm nose radius and 0° negative rake offers a balance between strength and precision. The robust cutting edge tolerates heavier cuts while the compact nose radius assists in achieving defined part contours. The standardised ISO-style designation simplifies toolholder selection and repeatable indexation, making fixture changes and tool requalification faster and more reliable across batch runs.

Economic benefits through longer service intervals

By combining a wear-resistant WMP20G grade with a high-performance coating, the insert extends the time between indexings and replacements. Fewer interruptions for tool changes translate into higher machine uptime and lower tooling consumption per part. For production environments where predictability and throughput matter, the improved life expectancy contributes directly to reduced unit costs and a more efficient machining schedule.

FAQ

What materials is this insert suitable for?
The CNMG120404-FM5 WMP20G insert is designed primarily for stainless steels (ISO M) and performs well under medium to robust machining conditions.

How does the Tiger·tec Gold coating benefit machining?
The Tiger·tec Gold coating on the WMP20G grade increases heat resistance and reduces wear, helping the insert maintain a stable cutting edge and extend service life during operations on tough alloys.

What is the purpose of the FM5 chipbreaker?
The FM5 chipbreaker promotes controlled chip formation and evacuation, improving process reliability and surface finish while reducing the risk of built-up edge on stainless materials.

Can the insert be used in interrupted cuts or heavy feeds?
Yes — the rhombic 80° geometry and 0.4 mm corner radius, combined with a negative rake, provide robustness suitable for interrupted cuts and heavier feed applications.

How is the insert referenced for toolholder selection?
Use the ISO-style designation CNMG120404-FM5 WMP20G to identify compatible toolholders and indexation requirements for consistent setup and repeatability.
