SPMT09T304-MP4 WPP20G — Indexable turning insert, Tiger·tec Gold coating, Walter Tools

A SPMT09T304-MP4 WPP20G indexable turning insert engineered for universal steel machining with a coated cemented carbide grade for reliable performance in diverse production environments

• Tiger·tec Gold coated cemented carbide
• Grade WPP20G for steel machining
• MP4 chipbreaker for stable chip control
• 0.4 mm corner radius for fine finishing

Consistent performance for steel machining

The combination of the Tiger·tec Gold coating and the WPP20G grade provides a balance of wear resistance and toughness optimised for machining steel. The coated cemented carbide substrate reduces flank wear and extends edge life under the heat and strain typical of steel turning. Because the grade is tuned to handle the thermal and mechanical loads of P-group materials, users gain more predictable tool life and fewer interruptions for index changes, which improves throughput and lowers per-part tooling costs.

Improved chip control and surface quality

Equipped with the MP4 chipbreaker and a 0.4 mm corner radius, this insert offers controlled chip formation and reduced risk of built-up edge. The chip geometry promotes short, segmented chips that evacuate reliably even in counterproductive cutting directions, aiding process stability. The modest corner radius supports fine surface finishes without sacrificing edge strength, making the geometry suitable for finishing passes where dimensional accuracy and appearance matter.

Designed for productivity and process security

The square 90° insert form and an 11° clearance angle deliver robust cutting edges and good radial support in typical turning holders. The SPMT form is well suited for a range of turning operations from light finishing to moderate roughing when paired with appropriate cutting parameters. The insert’s tolerance class M ensures consistent interchangeability across toolholders, supporting repeatable results in serial production. Together, these attributes reduce downtime and enable predictable planning of tool-change intervals.

FAQ

What materials is this insert intended for?
The SPMT09T304-MP4 WPP20G is specified for the P material group and is optimised for machining steel.

How does the Tiger·tec Gold coating help in production?
The Tiger·tec Gold coating on the WPP20G grade increases wear resistance and edge stability, improving tool life and process reliability in steel turning.

Which chip control behaviour can be expected from the MP4 chipbreaker?
The MP4 chipbreaker promotes controlled, segmented chips for safe evacuation and stable cutting, particularly beneficial in medium to high material removal rates.

Is the insert suitable for finishing operations?
With a 0.4 mm corner radius and the square 90° form, the insert is well suited for fine finishing where good surface quality and dimensional control are required.

Can this insert be used in standard SPMT toolholders?
Yes, the SPMT ISO designation indicates compatibility with standard SPMT turning toolholders that accept the same insert geometry.
