China threaded 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 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.
