SCMT09T308-E47 WPP20G – square 90° indexable insert for drilling/boring, Tiger‑tec Gold (Walter Tools)

The SCMT09T308‑E47 WPP20G is a square 90° indexable insert intended for drilling and boring in steel; optimised to deliver consistent chip formation and extended tool life under typical steel cutting conditions

• Tiger‑tec Gold coating for high wear resistance
• E47 chipbreaker for consistent chip control
• Square 90° form with 0.8 mm corner radius
• Optimised for steel machining (ISO P)

High wear resistance for sustained productivity

The combination of the Tiger‑tec Gold coating and the WPP20G grade provides a robust coated carbide surface that balances wear resistance with toughness. This makes the insert particularly suited to the thermal and mechanical demands of steel machining. The coating reduces flank and crater wear during continuous operation, which supports longer tool life and fewer indexings. Where process stability and predictable performance are priorities, the E47 chipbreaker further contributes by shaping chips to improve evacuation and reduce the likelihood of re-cutting, resulting in steadier cycle times and less machine downtime.

Stable geometry that improves hole quality and repeatability

A square 90° plate form combined with a 0.8 mm corner radius and a clearance angle of 7° yields a stable cutting edge for drilling and boring operations. The specified tolerance class M and plate thickness T3 support secure clamping and repeatable positioning in the toolholder, helping to maintain concentricity and surface finish across multiple indexings. These geometric attributes translate into fewer rejects and reduced secondary operations, which is particularly beneficial in production runs where dimensional consistency is essential.

Application focus and process advantages for steel workpieces

Designed for the ISO P material group, this insert is suitable for unalloyed and alloyed steels, where typical chip formation and heat generation demand a dedicated grade. The WPP20G grade is engineered to offer a compromise between wear resistance and toughness, making it a versatile choice across a range of cutting conditions. For shops seeking improved throughput, the insert’s combination of coating, chipbreaker and geometry supports higher effective cutting lengths and consistent surface integrity, helping to lower total machining cost per hole over time.

FAQ

Which materials is this insert suitable for? The SCMT09T308‑E47 WPP20G insert is specified for the ISO P group and is suitable for machining steel, including unalloyed and alloyed steels, as described for the WPP20G grade.

What advantages does the Tiger‑tec Gold WPP20G grade provide? The Tiger‑tec Gold WPP20G grade offers a coated carbide solution that improves wear resistance while maintaining toughness, which leads to longer tool life and stable machining performance in steel applications.

How does the E47 chipbreaker affect machining? The E47 chipbreaker produces controlled chips that evacuate more reliably from the hole, reducing re-cutting and contributing to steadier cutting forces and improved surface quality during drilling and boring.

Why is the 0.8 mm corner radius important? A 0.8 mm corner radius increases edge strength and helps resist chipping under interrupted cuts or higher feed rates, supporting consistent hole geometry and fewer edge failures.
