6 FAQs about [Down-the-hole drill assembly instructions]
How does a down-the-hole drill work?
Down-the-hole drills consist of various components such as hammers, bits, and pipes that work together to create boreholes. The hammer delivers rapid blows to the bit, while air pressure removes debris from the hole. These tools are designed to withstand high-impact forces and provide exceptional performance in challenging environments.
Can a hammer be used to drill a hole?
When drilling holes in water-bearing rock, never leave the ham-mer at the hole bottom with the air supply switched off. If drilling is to be suspended temporarily, always pull up the hammer by at least two pipe lengths. Clean around the driver chuck before changing the drill bit. Make sure the shank of the new drill bit is clean.
