SPMW09T308-A57 WPP35G milling indexable insert — square 90°, Tiger·tec Gold, Walter Tools

SPMW09T308-A57 WPP35G is a square 90° milling insert designed for productive steel machining with a robust chipbreaker and a high-performance Tiger·tec Gold coating

• Tiger·tec Gold coating for extended tool life
• Suitable for steel machining (ISO group P)
• Square 90° form with 0.8 mm corner radius
• 11° clearance angle with chipbreaker A57

Achieve higher productivity with predictable tool life

The combination of the WPP35G grade and Tiger·tec Gold coating provides a balance of wear resistance and toughness that translates directly into longer service intervals and fewer unplanned tool changes. For machining steels, the coating supports stable chip formation and reduces adhesive wear at elevated temperatures, which increases component throughput and lowers cost per part. The result is a measurable improvement in process efficiency without sacrificing surface quality.

Improved process stability through chip control and edge geometry

The integrated A57 chipbreaker and the 11° clearance angle promote effective chip evacuation and thermal stability during interrupted cuts. The square 90° form with a 0.8 mm corner radius offers a robust cutting edge that resists chipping while maintaining acceptable surface finish for medium to finishing operations. Combined with the T3 plate thickness, this geometry helps maintain cutting-edge integrity under varied milling conditions.

Flexible performance across steel grades and straightforward indexing

Engineered for ISO group P, the insert is suitable for unalloyed and alloyed steels, covering universal to tougher applications thanks to its graded toughness. The indexable design reduces downtime: worn edges can be rotated quickly, restoring cutting performance without removing the tool body. This simplicity supports lean machining workflows and benefits production environments that demand consistent repeatability.

Practical application notes for reliable results

When used in a suitable toolholder and matched to recommended cutting data for steel, the insert delivers stable machining and consistent component quality. The SPMW09T308-A57 WPP35G excels in operations where a balance between tool life and surface integrity is required.

FAQ

What materials is this insert suitable for?
The insert is designed for machining steels and is classified for ISO group P; the WPP35G grade and Tiger·tec Gold coating are optimised for unalloyed and alloyed steels.

How does the A57 chipbreaker affect performance?
The A57 chipbreaker promotes controlled chip formation and evacuation, improving process stability and reducing the risk of built-up edge during steel milling.

What is the significance of the 0.8 mm corner radius?
A 0.8 mm corner radius provides increased edge strength compared with smaller radii, helping to prevent chipping while maintaining a good surface finish for medium to finishing passes.

Is the insert compatible with standard toolholders?
The insert follows common ISO indexable insert dimensions and the ISO designation SPMW09T308-A57 WPP35G allows selection of compatible toolholders for square 90° inserts.
