KINGDRILLING DTH taper drill bit description:
To accomplish drilling operations through the taper connection on the drill bit and drill pipe, the tapered button drill bit is mostly utilized in conjunction with a pneumatic rock drill and a tapered drill pipe. Cone drill bits are mostly utilized in secondary crushing, drifting, anchoring, and other fields in mines. They are excellent for drilling hard rock. The cross and chisel drill bits were updated to create the taper drill bit. The drill bit has a long service life and good performance since it uses a hot-dip skirt and tungsten carbide bit. Twelve, eleven, and seven degrees are the standard taper angles for tapered drill bits.
Our company offers small hole rock drill bits: Tapered Drill Bit is different with thread button bit as long hole bit to use taper match with bit rod to be used for air leg or hand held jack hammerdriller in stone quarrying, and mineral.
