VBMT160406-MP4 WPP20G indexable turning insert — Tiger·tec Gold, MP4 chipbreaker for steel — Walter Tools

VBMT160406-MP4 WPP20G is a coated indexable turning insert designed for reliable steel machining in general turning operations, combining durable cutting performance with controlled chip formation.

• Tiger·tec Gold coating for long tool life
• MP4 chipbreaker for reliable chip control
• 0.6 mm nose radius for fine surface finish
• Rhombic 35° shape for versatile turning

Higher throughput on steel components

The combination of the Tiger·tec Gold coating and the WPP20G carbide grade delivers a high level of thermal and mechanical resistance tailored to steel machining. The coated grade is optimised for typical heat generation and chip formation encountered when turning unalloyed and alloyed steels, which results in extended tool life and fewer tool changes. By using a specialised chipbreaker such as MP4, stable machining is promoted across a wide range of cutting parameters, helping to increase machine uptime and overall throughput.

Predictable chip control for safer production

Consistent chip behaviour reduces interruptions and cleaning time at the machining centre. The MP4 chipbreaker is designed to produce compact chips during medium and finishing cuts, improving operator safety and enabling automated part handling. The rhombic 35° geometry supports versatile turning directions and provides a balance between cutting edge strength and access to the workpiece, helping to maintain cycle times without compromising surface quality.

Improved surface finish with defined cutting edge

The small 0.6 mm nose radius is well suited for finishing passes where surface quality matters. A defined nose radius limits vibration and helps achieve the desired roughness levels on turned parts, particularly when combined with stable clamping and appropriate cutting parameters. Where tighter tolerances and repeatable finishes are required, this insert geometry supports finishing strategies while remaining robust enough for light semi-finishing duties.

Practical selection and workshop benefits

The insert follows a common ISO designation that simplifies tooling decisions in mixed-machine environments: the format and chipbreaker code make it straightforward to match to suitable tool holders and turning programmes. The VBMT160406-MP4 WPP20G is compatible with standard clamping systems for VBMT-style inserts, reducing the need for bespoke tooling and enabling quick changeover. This practicality supports lean workflows and reduces non-productive time in small-batch and serial production alike.

FAQ

What materials is this insert intended for?
This insert is specified for machining steel (material group P); the WPP20G grade and Tiger·tec Gold coating are tuned for the thermal and chip-formation characteristics of steels.

Which chip shape does the MP4 breaker produce?
The MP4 chipbreaker on this insert promotes compact, controllable chips suited to medium and finishing cuts, improving safety and automated handling.

Can this geometry be used for finishing operations?
Yes — the 0.6 mm nose radius and rhombic 35° shape support fine surface finishes while offering sufficient edge strength for light semi-finishing.

Is the insert compatible with standard VBMT tool holders?
The insert follows the ISO-based VBMT form, so it is compatible with holders designed for VBMT1604-style inserts when the holder accepts the MP4 chipbreaker configuration.

How does the Tiger·tec Gold series affect productivity?
Tiger·tec Gold coating enhances wear resistance and thermal stability, which helps extend tool life and maintain consistent performance during steel turning.
