H22x108mm shank hard rock drill tool drill rod or shank rod chiesel integral drill rod
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.
