CPMT09T308-MP4 WPP20G indexable turning insert – Walter Tools, 11° relief, rhombic 80°

The CPMT09T308-MP4 WPP20G is an indexable turning insert designed for robust steel machining under ISO P conditions, combining a Tiger‑tec Gold coating with an MP4 chipbreaker for consistent performance.

• Tiger‑tec Gold coating for long tool life
• Designed for steel machining (ISO P)
• Rhombic 80° form with 11° relief
• MP4 chipbreaker for reliable chip control

Higher productivity through durable coating and grade

The Tiger‑tec Gold-coated grade WPP20G offers a balanced hardness and toughness profile that improves lifetime under typical steel cutting temperatures. As an indexable insert it delivers repeatable results for batch or single-component production, reducing costly tool changes. The coated hardmetal substrate helps to maintain a stable cutting edge and minimise flank wear over extended cycles, which in turn lowers per-part machining cost while maintaining consistent dimensional accuracy.

Reliable chip formation and surface integrity

The integrated MP4 chipbreaker is tuned to the rhombic 80° geometry and the 11° relief to produce controllable chip segments when turning steels. This results in reduced risk of built-up edge and improved workpiece surface quality. The modest 0.8 mm corner radius offers a compromise between strength and fine finish, suitable for general finishing and semi-finishing passes where a balance of edge life and surface appearance is required.

Clear specifications that support process planning

The insert is supplied in the CPMT09T308-MP4 format and is available in the T3 thickness variant; the designation indicates compatibility with standard indexable toolholders for rhombic inserts. The grade is explicitly targeted at ISO P materials (steel), making it suitable for unalloyed and alloyed steels with typical heat generation and chip behaviour. Engineers can therefore plan cutting data conservatively around a combination of coating benefits and chipbreaker geometry to extend productivity and process security.

Practical procurement and application support

For complex or high-volume applications the grade’s universality simplifies tool inventory: one coated grade covers a wide range of steel components, reducing the number of different inserts required. For specific cutting data, holder recommendations or to verify suitability for an application, Metav Werkzeuge provides technical consultation and samples on request; technical enquiries are handled by the sales team with industry experience and clear, application‑oriented advice.

FAQ

Which materials is this insert suitable for?
The CPMT09T308-MP4 WPP20G is specified for ISO P materials, i.e. for the machining of steel (unalloyed and alloyed steels).

What coating and grade does the insert use?
The insert uses the Tiger‑tec Gold coating and the WPP20G grade, a coated cemented carbide designed for a balance of wear resistance and toughness.

How does the MP4 chipbreaker affect machining?
The MP4 chipbreaker promotes reliable chip control in steel turning operations and supports stable surface finish when combined with the rhombic 80° geometry.

What edge preparation and geometry are specified?
The insert features an 11° relief angle and a 0.8 mm corner radius on a rhombic 80° form, suitable for semi-finishing and finishing passes in steel.

Is the CPMT09T308-MP4 available for standard toolholders?
The CPMT09T308-MP4 designation corresponds to common indexable insert formats and fits holders designed for rhombic 80° inserts of size 09.
