TCMT16T304-RM4 WMP20S turning/boring indexable insert — triangle 60°, RM4 chipbreaker — Walter Tools

TCMT16T304-RM4 WMP20S is a coated carbide indexable insert designed for drill/ream and turning tasks, optimised for rostfreier Stahl and medium to heavy-duty conditions

• Tiger·tec Silver coated grade WMP20S
• Optimised for rostfreier Stahl machining
• Triangle 60° form with 0.4 mm corner radius
• RM4 chipbreaker for secure chip control

High process security for rostfreier Stahl machining

The combination of the Tiger·tec Silver coating and the WMP20S carbide grade offers a balanced response to the typical machining challenges of rostfreier Stahl: material toughness, built-up edge tendency and heat generation. The coating reduces friction and supports stable chip formation, which translates into fewer interruptions and more predictable tool life. For operators unfamiliar with coating technology: Tiger·tec Silver is a multi-layer PVD/CVD-inspired system that enhances wear resistance and thermal stability, enabling consistent cutting performance under varying cutting speeds and feeds.

Geometry and chip control that improve surface finish and cycle times

The triangular 60° plate form combined with the RM4 chipbreaker and a 0.4 mm corner radius is engineered to produce short, controllable chips while maintaining a robust cutting edge. The 7° free or relief angle and the plate thickness T3 contribute to a stable cutting action and load distribution across the insert, which helps to reduce vibrations and protect the cutting edge during interrupted cuts. This geometry is particularly suitable where a fine surface finish and dimensional consistency are required in production turning and boring operations.

Economical productivity through predictable edge life and versatile application

Using a coated, purpose‑matched grade for rostfreier Stahl leads to lower tooling cost per part thanks to extended edge life and reduced rework. The RM4 chipbreaker and the plate’s geometry reduce downtime for chip-handling and enable reliable swarf evacuation in many toolholder systems. For process engineers looking to standardise tooling, this insert supports productive machining across a range of medium to robust cutting conditions and helps simplify grade selection for rostfreier Stahl operations. If additional cutting data or holder compatibility checks are required, Metav Werkzeuge’s technical advisors can provide process recommendations.
