DrillMeister DMP -Secondary Shaft-
IMPROVED TOOL LIFE
Evaluation of the "AH9130" grade under existing head exchangable drill cutting conditions demonstrated a significant improvement in tool life while maintaining surface finish quality and chip control performance.
The number of drilled holes increased from 1,000 to 2,000 per corner, and the total drilling length doubled from 100 m to 200 m.
