VBMT160404-MM4 WMP20G — Indexable turning insert, Tiger·tec Gold, for stainless steel

VBMT160404-MM4 WMP20G is a rhombic 35° coated carbide turning insert designed for machining stainless steels in medium to robust conditions.

• Tiger·tec Gold coating for high tool life
• Designed for stainless steel machining
• MM4 chipbreaker for stable chip control
• Rhombic 35° shape with 0.4 mm corner radius

Predictable metal removal and consistent chip behaviour

The Tiger·tec Gold coating, applied to a coated carbide substrate, promotes stable chip formation and reduces the tendency for built-up edge when machining tough, tenacious materials such as stainless steels. The coating's wear resistance supports longer cutting intervals and steady dimensional performance, which in turn improves process predictability and reduces unscheduled tool changes. For operations where consistent cycle times matter, the combination of coating and substrate enables dependable material removal rates under varying cutting conditions.

Precise geometry for improved surface quality and tool life

A rhombic 35° cutting geometry with a 0.4 mm corner radius and 5° clearance provides a controlled engagement with the workpiece, lowering cutting forces and helping to preserve the cutting edge. The MM4 chipbreaker is engineered to segment and evacuate chips consistently, reducing vibrations and the risk of surface damage. For technicians unfamiliar with chipbreaker function: it alters chip curl and thickness so chips break into manageable fragments, improving safety and surface finish without sacrificing productivity.

Engineered for shop-floor productivity and process security

The insert is available in size 16 with plate thickness 04, engineered to tolerate medium to robust turning tasks typical of stainless-steel components. Manufactured by a recognized brand in precision tooling, the design balances edge strength and cutting economy to deliver fewer interruptions and reliable batch-to-batch performance. This makes the insert suitable for production environments aiming for stable throughput and repeatable part quality, while benefiting from the optimised wear resistance of the Tiger·tec Gold series.
