DrillMeister -Fitting connecter- Longer Tool Life in INCONEL 718 Drilling
IMPROVED TOOL LIFE
In drilling operations for INCONEL 718, replacing the conventional DMP118 head with the DMM118 head optimized for heat-resistant alloys improved tool life from 100 to 160 holes without changing cutting conditions, achieving a 60% increase in tool life. The total machined length increased from 1,000 mm to 1,600 mm while maintaining stable machining performance
