DrillMeister -Spacer part- DMH head eliminated chipping issues
IMPROVED TOOL LIFE AND PRODUCTIVITY
In this application, edge chipping caused by shallow through-hole drilling and low machine rigidity was the main challenge.
By applying the high-edge-strength DMH head, stable machining was achieved while increasing cutting speed by approximately 20%.
Tool life improved from 4,000 holes to 8,000 holes, doubling the service life and delivering both higher productivity and longer tool life.
