Product Description

Product Introduction
Down-the-hole (DTH) bits are used with Down-the-hole hammers for drilling holes through a wide range of rocks types. In conjunction with DTH hammers, drill hammer bits are designed with a splined drive for rotating the bit in the ground. Drill bits are available in different sizes and different styles so they can drill a wide range of hole sizes.
DTH drilling has the feature of efficiency and flexibility.  It's a commonly used method in the mining industry (blast hole drilling), waterwell drilling, construction, and in the oil and gas industry. In DTH drilling, the drill string rotates while the drilling hammer continuously strikes down into the rock.Inside the hammer, a piston powered by compressed air gives the drill bit its striking power. This combined with the rotational movement means the rock is crushed in a very efficient manner.

DTH Bit Face Introduction
Concave Face design 
For medium soft to medium hard rock conditions in consolidated ground conditions in medium abrasivity rock. Front face grooves provide excellent cuttings removal and the concave center provides optimal hole straightness. The concave design is the most common bit shape. 
Convex Face design 
For medium sotf to medium hard rock in good ground conditions where maximum penetration rate is desired. The convex design will handle abrasive formations better than a concave or flat design. The convex design also enables the use of greater insert density for aggressive spherical, conical or ballistic tipped bits.
Flat Face design 
For hard rock formations where a very durable head is required. The flat face design is very stable and forgiving in fractured, voided or unconsolidated formations. The flat face design also handles abrasive formations well. Some models are available with face slots for improved hole cleaning.
