Tapered drill rods are also known as tapered drill steels, collared rods and pneumatic rods, which are driven by light pneumatic or hydraulic rock drills for drilling small holes with taper bits. The tapered drill rods normally has diameter of H22 and H25, taper degree of 4, 6, 7, 11, and 12, and length of 400mm-5000mm. The tapered drill rods are widely used in mining, tunneling, bolting, quarrying, construction, etc.
The taper column tooth drill bit is also referred to as a taper ball-tooth bit. It is a type of rock drilling tool that is used in conjunction with the taper of the drill bit body and the taper of the drill rod.
Tapered blade bits mainly include horseshoe chisel bit and oblique-chipway chisel bits and cross bits. Among these, the horseshoe chisel bits and the oblique-chipway chisel bits are mainly used for drilling small holes and short holes, and the cross bits are used for drilling long holes in hard and crack rock conditions. The tapered blade bits are mainly used in mining, quarrying, tunneling, bolting, etc.
Hydraulic rock drill is driven by high pressure oil to complete energy conversion in the percussive drilling system. Drill rod and coupling transfer the power to drill bit for drilling blast hole by breaking rocks. The hydraulic rock drill is the key equipment in the percussive drilling system.
