Thread button drill bits are made by high quality alloy steel bar and tungsten carbides, Through heat treatment, our drilling tools aretough enough to meet rock driline 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
and hard rock.
In order to better resist the abrasiveness of rock, spherical shape will be a good option for the carbide if high speed is not a necessity.
Rock Drill Thread Button Bits is suitable for R22, R25,R28,R32, R35,R38,T38,T45,T51,ST58,T60 rock drill rods use,it have many thread
It’s widely used for hard rock(f=8~18) drilling use.
