Optimised FM5 chipformer for stable chips
0.8 mm nose radius for consistent finishes
Rhombic 55° geometry with 0° negative rake

Increased component quality through coating and grade

The combination of the Tiger·tec Gold coating and the WMP20G cutting grade is engineered for turning rostfreier Stahl, a material group prone to tough machining conditions and built-up edge formation. The advanced coating reduces wear and supports a secure edge when temperatures rise, while the grade chemistry promotes stable chip formation under medium to robust cutting conditions. For production environments requiring repeatable surface finish and predictable tool life, this insert delivers measurable improvements in process reliability.

Geometry and chip control for reliable turning operations

The insert’s FM5 chipbreaker and rhombic 55° form are tuned to manage chips and reduce vibrations during interrupted cuts. The 0.8 mm nose radius helps produce consistent surface finishes without sacrificing strength at the cutting edge, and the 0° (negative) relief angle contributes to a robust cutting geometry that resists edge chipping. These design choices lower the risk of unexpected tool changeovers and improve cycle-to-cycle consistency in series production or demanding one-off work.

Productivity advantages for workshops and production lines

As an indexable insert, the component minimises downtime: edges can be indexed quickly to restore cutting performance without regrinding. The insert’s stable cutting characteristics reduce scrap rates and help maintain throughput in batch production. For shops processing rostfreier Stahl where flank and crater wear are critical, the insert’s features support longer service intervals and fewer process interruptions, translating into better machine utilisation and predictable output rates.

Practical considerations and recommended application zones

This insert is intended primarily for rostfreier Stahl machining under medium to robust conditions; the WMP20G grade provides a balance between wear resistance and edge toughness for such applications. The FM5 chipformer aids in producing manageable chip shapes during typical turning passes. For best results, pair the insert with suitable toolholders and set feeds/speeds according to machine rigidity and part geometry; trial cuts with incremental adjustments will identify the optimal parameters for each rostfreier Stahl alloy.
