6 FAQs about [The down-the-hole drill operating rod is broken]

What is DTH drilling?

nd as drilling progresses. DTH drilling is primarily percussive drilling using the energy imparted by the hammer piston t the rock through the bit. Any attempts to apply too much weight could damage the bit, hammer and drill string and

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.

What happens if a drill is worn out?

Replace any worn out parts, following manufacturer’s recommended discard limits closely. Snake skin is a wear pattern of micro cracks that develop from drilling fatigue in non-abrasive rock. The cracks will eventually penetrate deeper and cause large chunks to break away, see F8, F9, F12, & F13.

What is a DTH drill bit?

ld be carefully monitored.DTH drill bits are rotary - PERCUSSIVE tools with he emphasis on PERCUSSIVE. Their function is to fracture the material being drilled which should then be immediately carri

What happens if a drill rig is not set-up correctly?

The rig must be set-up correctly in order to give stability and safety. If this is not done, the effects of feed force and rotation torque can cause the rig to move or even to over-turn. This could result in serious or fatal injury as well as damage to the drill rig and equipment.

How does a drill bit work?

A built-in damping chamber cushions the piston return stroke and increases the impact frequency. After the compressed air has imparted most of its pressure en-ergy to the piston, it is led as exhaust air through airchannels on the splines of drill bit and chuck. The exhaust air then emerges as flushing air through holes in the drill bit head.
