CNMG120408-MW5 WMP20G indexable turning insert – Tiger·tec Gold, suited for rostfreier Stahl (Walter Tools)

The CNMG120408-MW5 WMP20G is a negative, rhombic 80° indexable insert designed for medium to robust turning of rostfreier Stahl in industrial production environments.

• Tiger·tec Gold coating for reliable edge life
• Optimised MW5 chipbreaker for secure chip control
• Rhombic 80° insert with 0.8 mm corner radius
• Negative 0° rake for robust cutting forces

Consistent wear resistance from advanced coating technology

The Tiger·tec Gold technology and the WMP20G coated carbide grade combine to provide a balanced hardness and thermal resistance that extends edge life under demanding conditions. This coating reduces flank wear and supports repeatable tool life, which leads to fewer tool changes and more predictable production cycles. For industrial turning where downtime and tool consumption impact throughput, the coating offers a clear, measurable advantage.

Predictable chip formation and improved process security

The MW5 chipbreaker is engineered to produce short, controllable chips when machining tough alloys such as rostfreier Stahl (ISO group M). Controlled chip formation reduces the risk of built-up edge and workpiece surface damage, helping to maintain stable cutting conditions. In practical terms, improved chip control simplifies swarf handling and reduces the likelihood of machine stoppages due to tangled chips.

Geometry designed for robustness and surface quality

With a Rhombic 80° form, a 0.8 mm corner radius and a 0° (negative) rake angle, the insert geometry prioritises strength and dimensional stability during moderate to heavy cuts. The negative rake increases edge support and resists chipping under interrupted cuts or heavy radial engagement, while the corner radius balances edge strength with achievable surface finish. These geometric choices make the insert suitable for shop-floor applications requiring reliable performance across varied cut depths.

Application suitability and machining recommendations

This insert is specified for machining rostfreier Stahl where material toughness and heat generation demand a composition that supports secure chip evacuation and edge integrity. The coated carbide grade performs well in typical stainless-steel turning tasks under medium to robust conditions; it is not optimised for soft aluminium or highly abrasive cast irons unless otherwise verified. For setup, choose coolant and cutting parameters that favour stable temperatures and consistent chip breaking to prolong tool life and maintain part quality.
