Bohr-/Aufbohrwendeschneidplatte / Drehwendeschneidplatte SCMT120408-RM4 WMP30G by Walter Tools — Tiger·tec Gold coating, for stainless steels

SCMT120408-RM4 WMP30G is a square turning and boring insert engineered for demanding machining of stainless steels, offering robust chip control and a reliable coated-carbide grade for medium to heavy-duty applications.

• Tiger·tec Gold coated carbide
• Optimised chip control RM4
• Square 90° geometry for stable cuts

Consistent performance on stainless steels with modern coating technology

The insert combines the WMP30G grade and the Tiger·tec Gold coating to address the challenges of machining stainless steels, where heat and material toughness often cause build-up and unstable chips. The coating reduces friction and supports a stable cutting edge, which in turn lowers the risk of edge chipping and prolongs tool life. This technical pairing delivers predictable cycle times and contributes to reduced rework, making it suitable for serial production environments that demand repeatable results.

Predictable geometry for accurate, repeatable turning

The square 90° geometry and a corner radius of 0.8 mm provide mechanical rigidity and consistent contact conditions at the cutting zone. The 7° relief angle helps to maintain clearance and minimise rubbing, while the compact plate form stabilises the toolholder interface. These geometric traits support a steady metal removal process and simplify setting-up and programming, which benefits shops aiming for reproducible component tolerances and surface quality.

RM4 chipbreaker and application guidance for productive machining

The RM4 chipbreaker is designed to support secure chip formation in the tougher stainless steel group, promoting short, manageable chips and reducing the likelihood of entanglement or surface damage. For medium to robust cutting conditions, this combination of geometry and chip control helps to maintain surface finish and reduce downtime caused by manual chip handling. The insert is supplied as a coated carbide grade intended specifically for stainless steels, making it a pragmatic choice when process security and consistent tool life are priorities in production.
