CCMT120408-MP6 WPP30G indexable turning insert — Tiger·tec Gold coating, for steel — Walter Tools

CCMT120408-MP6 WPP30G is a rhombic 80° indexable turning insert designed for efficient machining of steel with a coated carbide grade optimised for typical steel heat and chip formation

• Tiger·tec Gold coating for wear resistance
• MP6 chipbreaker for controlled chip formation
• Rhombus 80° geometry for versatile turning
• 0.8 mm corner radius for stable edge life

High productivity through coating and material pairing

The CCMT120408-MP6 WPP30G insert combines a coated carbide grade with the Tiger·tec Gold technology to address the thermal and chip-formation challenges of steel machining. The WPP30G grade is formulated for a balance between wear resistance and toughness, making it suitable for a wide range of unalloyed and alloyed steels. By matching coating and substrate to the workpiece group P (steel), the insert delivers predictable tool behaviour and helps maintain cutting performance across medium-duty turning tasks, supporting consistent cycle times and fewer interruptions for tool changes.

Geometry that fits versatile turning tasks

The rhombic 80° shape together with a 7° clearance angle gives the insert a compact footprint for both finishing and light to medium roughing. The nominal size of 12 mm and a plate thickness corresponding to code 04 (≈4 mm) ensure compatibility with standard CCMT-style toolholders, while the 0.8 mm corner radius offers a compromise between edge strength and surface finish. These geometric parameters support a stable cutting edge and simplify integration into existing tool setups, reducing setup time and streamlining changeover procedures.

Chip control and surface integrity benefits

The MP6 chipbreaker is engineered for controlled chip formation in steel, reducing the risk of long, stringy chips that can foul the workpiece or tool. Improved chip control directly impacts process security by lowering the likelihood of interruptions and rework. In practice, a well-matched chipbreaker and grade help to produce consistent surface quality and repeatable dimensional results, which is particularly valuable in batch production and mixed-series environments where downtime and scrap must be minimised.

Manufacturer backing and process reliability

Produced under the Walter Tools portfolio, this insert benefits from established tooling know-how and production standards. The combination of a recognised coated grade and a proven chipbreaker concept offers manufacturing engineers a reliable option for standard turning operations in steel. Where process stability and predictable tool life matter, the insert supports efficient machining and simplified tool management, contributing to a more robust manufacturing process.

FAQ

Which materials can be machined with this insert?
The WPP30G grade is intended for group P materials; the insert is suitable for unalloyed and alloyed steel grades and for general turning applications in steel.

What are the key geometric values of the insert?
The insert features an 80° rhombic form, 7° clearance angle, 0.8 mm corner radius, nominal size 12 mm and a plate thickness matching code 04.

How does the MP6 chipbreaker influence machining?
The MP6 chipbreaker promotes controlled chip formation in steel, which improves process security, reduces chip-related interruptions and supports consistent surface quality.

Is the insert coated and what does that mean in practice?
Yes — the insert uses the Tiger·tec Gold coating technology in the WPP30G grade. The coating provides enhanced wear resistance while maintaining toughness for steel machining, aiding tool life and reliability.

Which toolholders are compatible with the CCMT120408-MP6 designation?
The CCMT120408 geometry corresponds to standard CCMT-style toolholders with an 80° rhombic seat; the insert is intended for such common turning holders.
