CNMG120404-MU5 WPP20G — Indexable Turning Insert, Tiger·tec Gold (Walter Tools)

A CNMG120404-MU5 WPP20G indexable turning insert engineered for versatile steel machining with a Tiger·tec Gold coated substrate and MU5 chipbreaker geometry

• Tiger·tec Gold coated for longer edge life
• Universal WPP20G grade optimised for steel
• 0.4 mm nose radius for dimensional control
• Rhombic 80° form for versatile turning
• Negative 0° rake for robust edge stability

Consistent productivity when machining steel

The Tiger·tec Gold coated grade delivers a measurable balance between wear resistance and toughness, which translates into longer tool life and fewer insert changes during production. With a universal WPP20G composition, the insert is designed specifically for machining steel (P) grades, accommodating the heat and chip formation typical of these materials. The MU5 chipbreaker promotes controlled chip flow and reduced risk of built-up edge, so cycle times become more predictable and overall process efficiency improves. For operations aiming to reduce downtime and secure repeatable results, this geometry supports a stable cutting regime and easier process windows.

Geometry and coating that reduce costs and increase reliability

The rhombic 80° shape combined with a 0.4 mm nose radius provides good dimensional control on finishing and semi-finishing passes while remaining robust enough for moderate depths of cut. The 0° (negative) rake angle gives a stronger cutting edge and improved resistance to edge chipping under interrupted cuts or unstable workholding. The Tiger·tec Gold coating, applied to a coated carbide substrate, reduces flank wear and maintains sharpness across longer production runs. Taken together, these features cut down on regrinds and insert replacements, improving cost-per-part and supporting higher throughput in small-batch and continuous-turning environments.

Practical application notes and setup guidance

For reliable results, select feeds and speeds aligned with steel machining recommendations and use coolant strategies consistent with the material and machine capabilities; the insert’s design supports conventional turning operations and performs well under typical industrial feeds. The MU5 chipbreaker is effective across a range of cutting conditions, so fewer tool variants are needed for mixed production. Tolerance class M ensures consistent fit and repeatable clamping in standard toolholders. When integrating this insert into existing tool systems, check holder compatibility for a CNMG 1204 form and ensure clamping achieves the specified seat contact to exploit the insert’s full accuracy potential.

FAQ

What materials is this insert intended for?
This insert is specified for machining steel; the WPP20G grade and MU5 chipbreaker are tuned to handle unalloyed and alloyed steel under typical cutting conditions.

How does the Tiger·tec Gold coating affect performance?
The Tiger·tec Gold coating on the CNMG120404-MU5 WPP20G increases wear resistance while maintaining edge toughness, resulting in longer service life and more predictable tool change intervals.

Can this insert be used for finishing and semi-finishing?
Yes; the rhombic 80° form and 0.4 mm nose radius make the insert suitable for both finishing and semi-finishing operations on steel components.

Is the negative 0° rake suitable for interrupted cuts?
The negative 0° rake and robust edge geometry improve resistance to chipping, making the insert well suited to interrupted cuts or less stable workholding scenarios.

Which chipbreaker should be chosen for mixed production?
The MU5 chipbreaker offers versatile chip control across a range of steel grades and cutting conditions, reducing the need for multiple chipbreaker types in mixed-production environments.
