SCMT09T308-RP4 WPP20G — square 90° turning insert, Tiger·tec Gold coating, Walter Tools

SCMT09T308-RP4 WPP20G is a square 90° insert designed for robust turning and boring applications in steel, featuring a 0.8 mm corner radius and a 7° clearance angle for consistent engagement

• Square 90° insert for robust turning
• Tiger·tec Gold coated for longer life
• Universal WPP20G grade for steel machining
• 0.8 mm corner radius for reliable finishes

Higher productivity through optimised coating and grade

The combination of the Tiger·tec Gold coating and the WPP20G grade delivers a balance of wear resistance and toughness tailored for steel machining. As a coated carbide insert, it resists abrasion and maintains cutting-edge integrity under the thermal and mechanical loads typical of ISO P materials. The integrated RP4 chipbreaker supports controlled chip formation, which reduces the risk of build-up and helps maintain consistent cycle times. These characteristics translate into fewer tool changes and improved uptime on production lathes and live-tooling centres.

Consistent part quality with a sturdy geometry

A square 90° plate form combined with a 0.8 mm corner radius provides edge strength for shoulder and profiling cuts while still allowing a good surface finish. The plate thickness T3 and the medium tolerance class M ensure sufficient rigidity for repeatable machining conditions. This geometry limits deflection in interrupted cuts and helps sustain dimensional accuracy across batches, leading to predictable component quality and lower rework rates for series production.

Process reliability and wider material coverage

The WPP20G grade is formulated as a universal solution for steel applications, accommodating both unalloyed and alloyed steels within ISO P. Its wear behaviour supports steady-state cutting and makes it suitable for mixed production environments where material grades vary. The insert’s design supports higher metal removal rates without disproportionate tool wear, contributing to shorter cycle times and improved overall process efficiency. Where tighter surface requirements or special alloys are in use, the insert’s robustness provides a reliable baseline for process optimisation.

Practical handling and shop-floor benefits

The insert’s identification as SCMT09T308-RP4 WPP20G simplifies tooling lists and reordering in busy production settings. Its universal orientation reduces the number of tool variants required in the tool crib, while the chipbreaker geometry helps with chip evacuation in standard turning and boring operations. If additional process data or cutting parameters are required for specific machine tools or materials, further technical guidance is available from our team to support setup and feed/speed selection — ensuring rapid integration into existing workflows.

FAQ

What materials is this insert suited for?
The SCMT09T308-RP4 WPP20G insert from Walter Tools is intended primarily for ISO P materials, meaning it is optimised for unalloyed and alloyed steels.

How does the Tiger·tec Gold coating affect tool life?
The Tiger·tec Gold coating on the WPP20G grade improves wear resistance under the heat and abrasion typical of steel machining, resulting in longer usable tool life and more consistent performance.

What is the benefit of the RP4 chipbreaker?
The RP4 chipbreaker promotes predictable chip formation and evacuation during turning and boring, reducing the likelihood of chip entanglement and improving process reliability on the shop floor.

Can this insert be used for finishing and shoulder cuts?
Yes — the 0.8 mm corner radius and square 90° geometry make the insert suitable for shoulder cuts and operations where a combination of edge strength and surface finish is required.
