DrillMeister DMM head -Connector –
IMPROVED TOOL LIFE
The DrillMeister (DMM head) was applied to drilling of SS400 material, achieving approximately 30% longer tool life compared to the conventional tool.
Under the same cutting conditions, it also suppressed chip elongation even in an external coolant environment, contributing to stable and reliable machining.
