HPD-SUS TWIST DRILLS
JOBBER
Application
Designed for high speed non-step 4D ~ 5D drilling.
Drilling in mild steel, cast iron, aluminum,
alloyed, tool steel, etc.
Advantage
Helical thinning - good chip removal, self-centering,
reducing thrust and improving accuracy.
Reinforced web and jobbers length-increasing
rigidity and suitable for 4D ~ 5D drilling.
Premium Cobalt HSS with superior TiN coating
- higher speed and feed, longer service life
High quality-good surface finishes, high productivity
and weeding second operation.
