SCMT120408-RM4 WMP20G – turning and boring indexable insert, Tiger‑tec Gold, Walter Tools

The SCMT120408-RM4 WMP20G is a square 90° indexable insert engineered for productive turning and boring of stainless steel components in medium to robust machining conditions

• Tiger‑tec Gold coating for enhanced wear resistance
• Optimised RM4 chipbreaker for stable chips
• Square 90° geometry with 0.8 mm corner radius
• Designed for machining stainless steel

Consistent performance on stainless steel

The combination of the WMP20G grade and Tiger‑tec Gold coating addresses the typical machining challenges of stainless steel, such as high ductility and thermal sensitivity. The coated cemented carbide substrate promotes reliable chip formation and reduces the tendency for built‑up edge, which in turn supports predictable tool life and consistent part tolerances. This makes the insert particularly suitable where dimensional stability and repeatable results are required in serial production.

Improved chip control and surface integrity

Equipped with the RM4 chipbreaker, the insert delivers controlled chip flow and reduced entanglement during interrupted cuts and variable feed conditions. The engineered chipformer minimises long, stringy chips and contributes to a better surface finish, lowering the need for secondary operations. As a result, cycle times are optimised and machine downtime for chip clearing is reduced, supporting a smoother production rhythm and higher overall equipment effectiveness.

Robust geometry for versatile cutting applications

The Square 90° form and a 0.8 mm corner radius provide a robust cutting edge that tolerates moderate radial engagement and supports both light finishing and more demanding stock removal. A 7° clearance angle reduces flank contact and heat build‑up, helping to maintain cutting edge integrity under higher temperatures typical of stainless steel machining. The insert’s compact dimensions (12 mm seat size) and standard thickness facilitate straightforward toolholder integration and reliable clamping.

Process advantages and economic rationale

Integrating this grade into production yields tangible process benefits: enhanced edge stability from the Tiger‑tec Gold technology leads to longer intervals between indexings, while the chip control lowers manual intervention and rework. For manufacturers seeking cost‑effective throughput, these factors translate into reduced tooling costs per part and improved machine utilisation. The insert’s design supports consistent cycle times and contributes to predictable maintenance planning, reinforcing process reliability in batch or continuous production.
