VCMT160404-MM4 WMP20G – Rhombic 35° turning insert by Walter Tools

The VCMT160404-MM4 WMP20G is a rhombic 35° indexable turning insert designed for productive machining of stainless steel under medium to robust cutting conditions.

• Tiger‑tec Gold coating for improved wear resistance
• Optimised MM4 chipbreaker for secure chip control
• 7° clearance angle for stable cutting performance

Reliable performance on stainless steel for consistent production

The combination of the WMP20G grade and the Tiger‑tec Gold coating supports secure chip formation and resistance to built-up edge when machining stainless steel. The coated cemented carbide substrate offers improved thermal stability and wear behaviour, which translates into longer edge life and fewer tool changes. For production environments where cycle time and repeatability matter, this insert provides a predictable cutting edge and reduced downtime.

Predictable chip control and surface quality for smoother cycles

The MM4 chipbreaker geometry is engineered to produce compact, controllable chips with a consistent break pattern, reducing the risk of entanglement and improving machine uptime. The rhombic 35° geometry, paired with a 0.4 mm corner radius, balances strength and finish capability: the geometry supports stable cutting at moderate depths while helping to maintain a fine surface quality on the workpiece. The 7° clearance angle further stabilises the cutting process and reduces rubbing during interrupted cuts.

Durable coating and practical compatibility for efficient tooling

Designed within the Tiger‑tec Gold series, the insert benefits from a modern multi-layer surface treatment that combines adhesion and hardness advantages typical of advanced coatings. The VCMT160404-MM4 format is compatible with standard toolholders for VCMT inserts, enabling straightforward integration into existing tool setups and fast index changes. With its coated carbide construction and profile, the insert is aimed at providing cost-efficient performance across batch and continuous turning operations.
