Downthehole drill
The advent of tungsten carbide for the drill bits (the first bits were allsteel) and the development of the button drill bit coupled with the introduction of high air pressures (25 bar plus) has meant that the DTH system can compete easily and efficiently with other drilling systems.
Review of Rock Properties Based on Drilling Parameters
Rate of Penetration The rate of penetration, also termed as penetration rate or drill rate, is the speed at which a drill bit breaks the rock under it to deepen the borehole. It is normally measured in meters per hour or meters per minute or meters per second in SI units. It is calculated as: = ∆ (1)

Difference between DTH(Down the Hole) Drilling and Top ...
· Purpose of rotation is to turn the drill bit a suitable new position for the next blow. It means the bit must rotate so the buttons on the bit are moved between each blow; Using the button bits, the periphery is turned about 10mm between blows. The optimum distance generates the biggest chips or cuttings and gives the most efficient drilling.
