High Pressure DTH Drill Bits Spherical Flat Face DHD3.5 for
Borehole
DTH rock drill bits have four kinds of button type
Spherical button : good wearing resistance, suited to hard ground,
abrasive to very abrasive.
Parabolic button : fast penetration,suited to medium to hard
rock,suitable for the mildly abrasive ground.
Conical button : fast penetration, suited for smaller diameter
bits, suited for all non-abrasive ground types.
Ballistic button : fast penetration,suited to soft rock, suitable
for non abrasive ground
