Consistent chip control and longer tool life for demanding turning

The combination of the FM5 chipbreaker and the Tiger·tec Gold coating delivers measurable improvements in chip formation and wear resistance. The chipbreaker is engineered to produce short, controllable chips when machining rostfreier Stahl, reducing the risk of built-up edge and improving component surface finish. The coating's multi-layer structure supports higher thermal stability and wear resistance, which translates into longer intervals between index changes and fewer unplanned stops. For production environments where cycle-time reliability matters, this insert sustains a predictable tool life and helps maintain process stability.

Geometry engineered for stability and reliable cutting results

The Rhombus 35° shape and 0.8 mm nose radius provide a balance between strength and profile definition: the nose radius supports a fine surface finish while the inclined geometry reduces cutting forces during interrupted cuts. The 0° negative rake delivers a robust cutting edge, especially advantageous in tougher stainless conditions where material toughness and heat generation are high. These geometric choices ensure the insert resists chipping under heavier depths of cut and provides repeatable dimensional accuracy—qualities that support efficient, high-quality turning in both batch and continuous production.

Application guidance and selection rationale for greater process security

Assigned to ISO group M, this grade is optimised for rostfreier Stahl under medium to heavy machining conditions. The WMP20G carbide grade is a coated cemented carbide designed to resist adhesion and thermal softening, facilitating steady cutting at typical stainless turning speeds. When selecting cutting parameters, favour moderate to high cutting speeds with stable feeds and ensure appropriate coolant or cutting fluid management to dissipate heat; this helps exploit the Tiger·tec Gold benefits fully. The insert’s design supports both roughing and semi-finishing tasks, offering a cost-effective combination of life expectancy and surface quality in industrial turning applications.
