SCMT120404-RP4 WPP20G – Boring/Turning indexable insert, Tiger·tec Gold, for steel (Walter Tools)

The SCMT120404-RP4 WPP20G is a square 90° indexable insert designed for versatile boring and turning applications in steel, offering a balanced mix of wear resistance and toughness for stable, productive machining.

• Tiger·tec Gold coating for extended tool life
• Optimised RP4 chipbreaker for stable chips
• 0.4 mm corner radius for precise finishing
• Square 90° form, 12 mm size, 7° clearance

High process reliability through coated carbide and chip control

The SCMT120404-RP4 WPP20G combines a coated carbide substrate with the Tiger·tec Gold coating technology to resist abrasive wear while maintaining edge strength. The RP4 chipbreaker is engineered for consistent chip segmentation in ISO P applications; this reduces the risk of built-up edge and improves thermal stability during interrupted cuts. For production environments where predictable tool life and fewer tool changes reduce downtime, the insert delivers measurable gains in machining uptime and repeatability.

Accurate surfaces and stronger edges for finishing passes

With a 0.4 mm corner radius and square 90° geometry, the insert supports controlled cutting forces and predictable tool deflection, which contributes to improved surface finish and dimensional stability. The 7° clearance angle helps to prevent rubbing on the flank face, limiting heat generation and ensuring a sharper cutting action. These design choices make the insert suitable for both roughing and light finishing passes on unalloyed and alloyed steel, where consistent part quality is required.

Practical economy and easy system integration

The insert’s specification—12 mm inscribed circle with a 4.0 mm thickness and tolerance class M—matches common indexable toolholders, enabling quick index changes and minimal setup time. The WPP20G grade offers a balanced performance profile (wear resistance and toughness) that suits a wide range of steel machining tasks, reducing the need for multiple specialised grades. For job shops and production lines seeking efficient material removal with predictable consumable costs, the insert supports a cost-effective workflow while maintaining surface quality and process security.
