Feature of product
Gentle Helix angle degrees and
shoulder R for drilling of
high hardened materials up to 70HRC
Adopted helix angle 15 degrees
and shoulder radius prevent chipping.
Thinning shape suitable for
high hardened materials
improved chip resistance at the center
of drill and chip evacuation.
Exclusive thinning for
high hardened materials
Web thickness is 1.6 times more
(compare with nomal carbide solid drill)
Stable drilling for high hardened materials
up to 70HRC by adopting “DH1” coating
By adopting “DH1” coating which provides high hardness
& oxidization resistance,
improved wear resistance and gives longer tool life.
Adopting micro grain carbide with high toughness,
improved chipping resistance.
FAQ about carbide drill
Is it possible to machining for carburization with EZ HARD DRILL?
Please Use EZ hard drills at first, and then STRIKE DRILL in the middle of machining.
※Please refer to the recommended cutting conditions for machining.
I am looking for a drill to remove a bolt breakage fracture.
We recommend EZ hard drill (EZH type).
A tool was broken when machining under catalog conditions. What are the countermeasures?
First, lower the feed speed. If it is not still working well, then lower the spindle speed as well.
