T38 4 Inch / 5 Inch Tungsten Carbide Hard Rock Mining Threaded
Button Drill Bit
Description
The 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.
