SCMT120412-FP4 WPP20G indexable turning insert for steel (P) — Walter Tools

The SCMT120412-FP4 WPP20G is a square 90° indexable insert with a Tiger·tec Gold coated carbide grade, optimised for turning steel in demanding production environments.

• Tiger·tec Gold coated carbide grade WPP20G
• Optimised FP4 chipbreaker for reliable chip control
• Square 90° geometry with 1.2 mm corner radius
• Suitable for steel (ISO P) machining

High productivity and cost efficiency for steel turning

The combination of the WPP20G coated carbide grade and the Tiger·tec Gold technology delivers a reliable balance between wear resistance and toughness, which translates into longer tool life and fewer indexings in production. When machining steel (ISO P), the coated substrate ensures stable chip formation, reduced flank wear and a consistent surface finish, so processes run with fewer interruptions. The insert’s design supports high metal removal rates without sacrificing dimensional stability, making it a pragmatic choice for workshops seeking predictable performance and lower unit costs over many cycles.

Predictable chip control and geometry that protects components

Equipped with the FP4 chipbreaker, the insert produces controlled chip forms suited to a wide range of turning operations, reducing the risk of entanglement and improving evacuation. The 90° square shape and a 1.2 mm corner radius combine to offer robust edge strength for interrupted cuts while maintaining the ability to produce accurate profiles and shoulders. A 7° clearance angle helps reduce rubbing and heat build-up at the cutting edge, supporting consistent cutting forces and repeatable results. Together these features decrease set-up time and contribute to a more stable machining window on batch or continuous production.

Material suitability and application guidance for reliable integration

This indexable insert is specifically formulated for steel applications (ISO group P) and is optimised for the typical heat and chip behaviour of unalloyed and alloyed steels. The coated carbide construction provides a broad workpiece coverage across steels classified under ISO P, with a bias towards universal performance in the WPP20G grade. The square configuration and the thickness designation allow straightforward use in standard turning toolholders; the FP4 chipformer simplifies selection of cutting parameters by stabilising chip shape, thereby aiding coolant and insertion strategies. For best results, match insert geometry to the operation—roughing or finishing—so the intended balance of tool life and surface quality is achieved.

FAQ

What workpiece materials suit this insert best?
The SCMT120412-FP4 WPP20G insert is formulated for machining steel (ISO group P) and performs well across unalloyed and alloyed steels thanks to the WPP20G grade and Tiger·tec Gold coating.

How does the FP4 chipbreaker influence machining?
The FP4 chipbreaker stabilises chip formation for predictable evacuation, which reduces risk of tangling and supports continuous turning operations with consistent cutting forces.

Can this insert be used for finishing operations?
Yes; the combination of a 1.2 mm corner radius and the coated carbide grade permits fine finishes when appropriate cutting parameters are selected, while still offering robustness for light interrupted cuts.

What are the geometric advantages of the square 90° shape?
A square 90° geometry provides strong cutting edges for shoulder work and interrupted cuts, and offers four indexable edges per insert, optimising economy in series production.

Is the Tiger·tec Gold coating beneficial for batch production?
The Tiger·tec Gold coating enhances wear resistance and maintains edge integrity under cyclic loading, making the insert well suited to batch and continuous production where repeatable results are essential.
