Thread Button bits
Thread button drill bitsare 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.
