Integral Steel Rod is used by a hand held drill machine in
Underground mining and for small hole drilling, 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, also it can be used for drilling
bore hole diameter from 30mm to 41mm usually.
Integral Drill Steels are a fixed length with a shank at one end
and a bit at the other ,and are able to drill to a depth equivalent
to their effective length.The bit may consist of single chisel
shaped tungsten carbide insert or three such inserts.
To drill deep holes,the rods are designed to be used in a series
where the length of any rod used in longer than the one used just
before it.
To do this ,a series of rods must be produced so that the bit
diameter is reduced for each increase in length if rod to prevent
jamming of the bit in the hole.
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.
