Hex22*108 Mining Tools Tungsten Carbide Tipped Shank Chisel Type
Integral Drill Steel Rock Drill Rods For Quarry
Describtion
Integral Drill Steels usually have forged collar, and are fixed
length with a shank at one end and a bit at the other. This
provides a hexagonal chuck section to provide leverage for the
rotation chuck bushing. They are able to drill to a depth
equivalent to their effective length. The bit may consist of a
single chisel shaped tungsten carbide insert or four such inserts.
Holes are typically drilled in 0.4m increments to accommodate the
air-leg feed length. To drill deep holes (up to 2.0m), the rods are
designed to be used in a series where the length of any rod used is
longer and the head size is slightly smaller than the one used just
before it in the sequence. To do this, a series of rods must be
produced so that the bit diameter is reduced for each increase in
length of rod to prevent jamming of the bit in the hole.
Integral Drill Steel is mainly used in small-hole drilling, such as
stone quarrying, foundation drilling,tunneling, underground mining,
road cutting, and trenching and so on, and equipped with small
power rock drills, like air leg rock drills, hand held rock drills,
etc. It can reduces the expense of impact energy, improves the
drilling speed and efficiency, which can be used for drilling bore
hole diameter from 23mm to 45mm usually.
