SCMT120412-RP4 WPP20G indexable insert — coated carbide for steel with RP4 chipbreaker

A SCMT120412-RP4 WPP20G indexable insert designed for drilling, boring and turning applications in steel where robust edge life and consistent chip control are required

• Tiger·tec Gold coated carbide grade WPP20G
• Designed for steel machining (ISO P)
• Square 90° form with 1.2 mm corner radius

Enhanced productivity through a proven coating and grade

The coated carbide WPP20G from the Tiger·tec Gold series delivers a reliable balance of wear resistance and toughness tailored to machining steel (ISO P). The grade is engineered to handle the typical heat and chip formation when cutting unalloyed and alloyed steels, reducing unexpected tool changes and downtime. By combining a wear-resistant coating with a geometry optimised for steel, the insert supports faster cycle times and predictable tool life, which in turn improves overall process stability and makes planning easier for production environments.

Consistent chip formation and cutting-edge stability

Built around the RP4 chipbreaker, the insert promotes short, controllable chips in many cutting conditions. The 7° clearance angle and 1.2 mm corner radius contribute to a stable cutting edge that reduces vibration and improves surface finish on machined components. This geometry helps maintain the integrity of the cutting edge under load, lowering the risk of built-up edge and providing a repeatable machining result — a clear advantage for demanding serial production or tight-tolerance operations.

Practical design that simplifies tool set-up

The square 90° plate form and nominal size of 12 mm make the insert straightforward to seat in common indexable holders, offering four usable cutting edges per insert and efficient tool utilisation. The tolerance class M indicates consistent dimensional accuracy for predictable clamping and runout behaviour. These design attributes reduce setup time and spare parts complexity, allowing toolrooms to keep more operations within existing fixture and holder inventories.

Application advice and machining scope

Assigned to ISO group P, the insert is primarily intended for machining steel; the WPP20G composition provides a balanced performance across different steel types, favouring a broad range from wear-resistant to more ductile batches. For general guidance: select moderate cutting speeds with appropriate coolant strategy for higher material removal, and use the RP4 chipformer to maintain short, segmented chips. The designation SCMT120412-RP4 WPP20G indicates the geometry and grade, facilitating straightforward replacement and tool management in production documentation.

FAQ

What materials is this insert suitable for? The SCMT120412-RP4 WPP20G is designed primarily for machining steel (ISO P); the WPP20G grade adapts to typical steel heat and chip formation.

How does the RP4 chipbreaker affect performance? The RP4 chipbreaker delivers controlled, short chips in a wide range of steel applications, improving chip evacuation and surface finish with the SCMT120412-RP4 WPP20G insert.

Which features support long tool life? The Tiger·tec Gold coating and the balanced WPP20G grade contribute to wear resistance and edge stability, extending the service life of the insert under normal cutting conditions.

Is the square form suitable for roughing and finishing? Yes — the square 90° form and 1.2 mm corner radius provide robustness for roughing while still allowing acceptable finishing capability when parameters are adjusted.

What does tolerance class M indicate for shop-floor use? Tolerance class M signifies consistent dimensional accuracy for reliable seating in holders and predictable runout behaviour, simplifying tool setup and repeatability
