DTH BIT

DTH is short for "down the hole". The down-the-hole drilling is used to produce large-diameter holes in rocks, usually in the initial stage prior to blasting, but it is also used in non-blasting applications. DTH drilling are used mostly in mining quarries but can be used in a variety of other construction applications. The DTH drilling method is growing in popularity, with increases in all application segments, including blast-hole, water well, foundation, oil & gas, cooling systems and drilling for heat exchange pumps. Applications were later found for the DTH method underground, where the direction of drilling is generally upwards instead of downwards.

DTH Bit Face Designs

	Flat Face Bit: Flat Face (F) design for medium hard to hard formations, good flushing and good penetration rates.
	Convex Bit: Convex (V) design with double gauge row for medium to hard and abrasive formations, good flushing and good penetration rates.
	Concave Bit: The all-purpose Concave (C), for soft to medium hard formations, straight holes, excellent flushing and fast penetration rates.
	Concave/Convex Bit: Concave/Convex Bit(X) the best of both worlds with double gauge row and concave center for medium to hard and abrasive formations, straight holes, excellent flushing and excellent penetration rates.
	Cyclops Bit: Cyclops unique single port design maximizes bit strength and minimizes the risk of bit head splitting or chunking caused by operational and manufacturing induced fatigue stress.
