SCMT120408-RP4 WPP20G square indexable insert – Tiger·tec Gold coating for steel machining (ISO P) by Walter Tools

SCMT120408-RP4 WPP20G is a square 90° indexable insert designed for turning and boring operations in steel, offering a Tiger·tec Gold coated carbide grade optimised for consistent performance

• Tiger·tec Gold coated carbide for high productivity
• RP4 chipbreaker for reliable chip control
• Square 90° geometry with 0.8 mm corner radius
• Designed for steel machining (ISO P)

Consistent productivity through optimised grade and chip control

The coated carbide grade WPP20G from the Tiger·tec Gold family delivers a robust balance between wear resistance and toughness, specifically designed for steel (ISO P) applications. The RP4 chipbreaker stabilises chip formation, reducing interruptions and helping to maintain cycle times. This combination means fewer unplanned tool changes and more predictable process windows, which in turn supports higher output and lower overall machining costs. The coating reduces flank and crater wear under the heat and pressures typical of steel turning, while the substrate provides the necessary toughness to resist edge chipping during interrupted cuts.

Geometry that secures component quality and tool life

A square 90° plate form with a 0.8 mm corner radius and 7° relief provides robust edge support and stable cutting behaviour. The corner radius helps distribute cutting forces and improves surface finish on standard turning operations, while the relief angle ensures acceptable clearance to avoid rubbing during engagement. These geometric decisions translate into repeatable dimensional accuracy and a reliable surface quality on finished parts. The insert’s dimensions are suitable for common toolholder systems that accept the SCMT120408 format, enabling straightforward integration into existing tool setups.

Practical benefits for workshop integration and process security

With tolerance class M and execution type T, the insert offers dependable fitment and repeatability. The grade and chipbreaker combination makes this insert suitable for a broad range of steel grades, from tougher machinable steels to more wear-prone alloys, improving process security across varying batch types. As an indexable insert, it supports cost-effective edge rotation and replacement strategies. For production environments seeking predictable tool life, the RP4 geometry and WPP20G performance help to reduce downtime and simplify inventory management, offering a clear route to more consistent throughput.

FAQ

What materials is this insert suitable for?
The SCMT120408-RP4 WPP20G is formulated for steel machining and is classified for ISO P applications, making it suitable for unalloyed and alloyed steels.

What benefit does the RP4 chipbreaker provide?
The RP4 chipbreaker on this insert improves chip control and promotes stable chip formation during turning and boring, which supports uninterrupted operation and consistent surface finishes.

How do the corner radius and relief angle affect performance?
A 0.8 mm corner radius provides edge strength and a better surface finish, while the 7° relief angle ensures adequate clearance to reduce rubbing and thermal build-up during cutting.

Is this insert compatible with standard SCMT120408 toolholders?
The designation SCMT120408 indicates the standard square insert format; compatibility depends on the toolholder accepting that insert size and clamping style.

What process advantages can be expected from the Tiger·tec Gold grade?
The Tiger·tec Gold grade (WPP20G) balances wear resistance and toughness for steel, offering improved tool life and process reliability in mixed production environments.
