CNMG120404-MS3 WS10 (CNMG120404-MS3) — Indexable Turning Insert, Rhombus 80° by Walter Tools

A CNMG120404-MS3 WS10 indexable turning insert engineered for universal external turning and finishing operations, featuring a rhombic 80° geometry with MS3 chip control and a negative 0° relief for stable edge behaviour.

• Coated carbide grade WS10 for broad applications
• MS3 chipbreaker for controlled chip formation
• Rhombic 80° geometry for universal turning
• 0° negative relief for robust edge stability

Robust cutting performance with consistent results

The insert delivers a reliable balance between edge strength and surface finish. The WS10 coated-carbide grade, combined with the MS3 chipbreaker, is designed for stable chip formation and reduced risk of built-up edge. The 0° negative relief increases edge support and is beneficial for interrupted cuts or when toolholder rigidity is limited. The 0.4 mm corner radius helps to distribute cutting forces and improves tool life while still enabling good surface quality. For engineers assessing process stability, these design choices translate into fewer tool changes and more predictable component quality.

Predictable chip control and machining efficiency

Controlled chips mean fewer stoppages and safer machining. The MS3 chipbreaker is shaped to produce short, manageable chips across a range of common turning conditions; this reduces cycle interruptions and supports uninterrupted production. The coated-carbide formulation provides wear resistance and thermal stability; however, material suitability should be checked against the product matrix since grade performance is catalog dependent. When optimising feeds and speeds, expect improved repeatability and a reduced need for manual chip management when using this insert in standard tool-holder setups.

Practical selection advice and application notes

The rhombic 80° form offers versatility for external turning and light profiling. The insert’s codes indicate geometry and size—use holders compatible with CNMG inserts and confirm clamping seat and tolerance class M for best fit. A higher corner radius like 0.4 mm favours tool life under heavier cut depths, while the negative relief supports edge security in unstable setups. If the correct grade for a specific alloy is unclear, consult the product matrix or contact technical support for recommended cutting data. Technical guidance and order information are available via Metav Werkzeuge; product matching ensures optimal performance and tool life.

FAQ

What types of turning is this insert best suited to?
The CNMG120404-MS3 WS10 insert is aimed at universal external turning tasks where a combination of edge strength and good chip control is required; its rhombic 80° form supports a variety of profiles.

Which chip control behaviour can be expected from MS3?
The MS3 chipbreaker on this insert promotes short, controllable chips under typical turning conditions, improving efficiency and reducing machine stoppages compared with uncontrolled chip formation.

Is the WS10 grade suitable for stainless or alloy steels?
WS10 is a coated-carbide grade; material suitability depends on the specific alloy and application—consult the product matrix or Metav Werkzeuge for confirmed recommendations.

How does the 0° negative relief affect machining?
A 0° negative relief increases edge support and stability, particularly useful in interrupted cuts or when clamping rigidity is less than ideal, helping to reduce edge chipping.

What does the 0.4 mm corner radius influence in practice?
A 0.4 mm corner radius provides improved tool strength and heat distribution for longer tool life while still delivering acceptable surface finish for many finishing and semi-finishing operations.
