6 FAQs about [DTH Drill Cylinder Disassembly Drawing]

How do you use a DTH drill?

Thrust should be kept as low as possible at all times to avoid excessive vibration in the drill string. Hold back should be increased more and more as additional rods are added and as drilling progresses. DTH drilling is primarily percussive drilling using the energy imparted by the hammer piston to the rock through the bit.

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

How do you use a DTH hammer?

Rotate the hammer clockwise at approximately 30-rpm. The DTH bit will now push into the Driver Sub and percussive action begins. When the hammer is lifted from the rock face, the DTH bit extends from the Driver Sub and percussive action ceases. Extra air will pass through the hammer, which can be used to flush the hole clean.

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

How much hold back should be increased in DTH drilling?

Hold back should be increased more and more as additional rods are added and as drilling progresses. DTH drilling is primarily percussive drilling using the energy imparted by the hammer piston to the rock through the bit. Any attempts to apply too much weight could damage the bit, hammer and drill string and impair the drilling rate.

How do you lubricate a DTH hammer?

If removed intact secure with wire or string before separating. Just like any other piece of precision machinery, the DTH hammer must be lubricated and small quantities of oil should be injected into the air stream at regular intervals while the hammer is working.
