DrillMeister DMF -I beam-
IMPROVED TOOL LIFE
I beam drilling by DrillMeister DMF with AH9130 grade achieved smooth and stable drilling even under less rigid work-holding conditions. Compared with the current tool, tool life increased by approximately 32% and table feed improved by approximately 5%. Large entrance and exit burrs were also eliminated, helping reduce secondary deburring operations and support reliable continuous production.
