General Introduction:


Acedrills is in the position to offer a comprehensive range of DTH drill bits with all diameters of the current prevailing manufacturers' hammer shank designs to match various drilling applications. All our DTH drill bits are also CAD designed, CNC manufactured for perfect bits body, and multiple heat-treated to enhance hardness, surface-compressed for fatigue resistance, all thus to extend the product life for maximum wear and performance in the toughest of drilling conditions. Moreover, all these bits are also made from high quality alloy steels and fitted with premium quality tungsten carbide tips for superior penetration rate.

Acedrills commonly has three basic bits head designs: Flat Face, Convex and Concave. These are designed for specific applications for all rock types, hardness's and conditions:

Selecting The Right Bits


Bit service life and penetration rate are the most important criteria in selecting the right bit for a particular application. In most cases, the focus is on productivity, so the bits of fast cuttings removal features are preferable, to ensure the buttons are cutting clean, with the minimum of re-crushing.

DTH bit is the tool cutting rocks, and subject to severe stress from the striking piston as well as from the abrasive cuttings passing the bit at high velocity. When selecting the right bit for optimum performance you have to balance penetration against bit life. On occasion you can successfully sacrifice bit life for penetration, remember the rule of thumb that states that a 10% increase in penetration covers at least a 20% loss in bit life.
