VCMT160412-RM4 WMP20G turning insert — Walter Tools, Tiger·tec Gold, for stainless steel

The VCMT160412-RM4 WMP20G is a rhombic 35° indexable turning insert designed for secure and repeatable cutting of stainless steel in medium to robust machining conditions.

• Tiger·tec Gold coating for longer tool life
• Optimised chipbreaker RM4 for stable chips
• 7° clearance angle for secure cutting
• Rhombus 35° geometry for versatile turning

Consistent performance through Tiger·tec Gold technology

The coated-carbide WMP20G grade, produced under Tiger·tec Gold technology, provides a balanced combination of wear resistance and edge stability. This results in predictable tool life when machining stainless steel, where workpiece toughness and heat generation typically challenge cutting edges. The coating supports controlled oxidation and thermal resistance, which helps to limit build-up and preserve a sharp cutting line; this means fewer interruptions for tool changes and steadier process windows in production environments.

Secure chip control and geometry that aids productivity

The insert’s RM4 chipbreaker and Rhombus 35° form promote effective chip segmentation and evacuation, reducing the risk of entanglement and inconsistent surface finish. The moderate 1.2 mm corner radius contributes to robust edge strength while allowing acceptable surface quality on external turning operations. Combined with the modest 7° clearance angle, the geometry supports stable engagement and repeatable cutting forces, which helps maintain spindle load consistency and tool-seat reliability during longer runs.

Application benefits and process reliability

Built for medium to robust cutting, this indexable insert supports operations where secure chip formation and predictable wear are priorities. The grade is optimised for the machining behaviour of stainless steel, addressing common issues such as work hardening and built-up edge. In practice, this leads to fewer stoppages for edge dressing and a smoother transition from roughing to finishing passes. Maintenance routines become more straightforward, and overall process stability improves, which contributes to higher throughput and reduced scrap rates.
