DrillMeister -Hydraulic L shaep valve- DMC
IMPROVED TOOL LIFE
The customer sought superior hole-making performance for processing stainless steel valves, but the current interchangeable head drill could not operate under enhanced conditions.
Additionally, the tool's lifespan was short, resulting in high tool costs.
By applying the DrillMeister DMC head, we achieved excellent machining accuracy with its self-centering design, and it also allowed for an extended tool life.
