DrillMeister DMP – Differential Case-
IMPROVED TOOL LIFE
In through-hole drilling of a differential case made from ductile cast iron, DrillMeister (TID190F20-1.5 with DMP195 AH9130 head) was tested under identical cutting conditions against the customer's current Solid carbide drill. DrillMeister achieved 8,000 holes per head compared with 3,000 holes for the competitor, delivering approximately 2.7 times longer tool life while maintaining the same productivity and chip evacuation performance.
