Introduction
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 is 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 of rod to prevent jamming of the bit in the hole.
The products in this brochure are the most commonly used. For other bit diameters and lengths.
Frequently Asked Questions
What are the available shank sizes for these integral drill rods?
The standard shank configurations include Hex22x108mm, Hex19mmx108mm, and Hex25mmx159mm to suit different pneumatic and hydraulic drill setups.
Which industries primarily use the Hex22 integral drill steels?
Hex22 x 108 mm integral drill steels are the most common selection within the dimensional stone quarrying industry, underground mining, and tunneling operations.
How does using an integral steel rod optimize drilling efficiency?
By integrating the shank and bit into a single solid component, it reduces the loss of impact energy through joints. This improves drilling speed, reduces overall operating costs, and yields higher efficiency.
What range of bit diameters and lengths do you supply?
We supply bit diameters ranging from 26mm to 42mm, with standard effective lengths starting from 400mm up to 8000mm.
How is jamming prevented when drilling deep holes?
To drill deep holes, a series of rods of increasing lengths must be used. For each increase in rod length, the bit diameter is slightly reduced to prevent the tool from jamming inside the pre-drilled hole.
What equipment is compatible with these integral rods?
These rods are designed for hand-held and air leg rock drills, making them ideal for small-hole mining operations and low-power drilling machines.
