Thread button drill bits are made by high quality alloy steel bar
and tungsten carbides. Through heat treatment, our drilling tools
are tough enough to meet rock drilling demands and have the least
loss of energy while drilling the rocks. Besides, we can design
customized thread button drill bits according to different drilling
application, and custom drill bits are applicable to drill soft
rock, loose-medium rock and hard rock.
