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.
