Rockmore International announces a new drill bit designed for percussive drilling applications in abrasive and challenging rock conditions.
Rockmore International announces a new drill bit design especially
suited for hard rock quarry drilling. The new CrossFlow bit is designed to help
extend bit life and improve penetration rates for percussive drilling
applications in abrasive and challenging rock conditions.
The CrossFlow bit incorporates new design features in the bit
face, particularly in the geometry and placement of flush holes, flush grooves
and tungsten buttons. The intent of the new bit geometry is to remove the
broken rock chips, that result from the percussive blows, away from the bit
face and up toward the hole annulus as quickly and effectively as possible. The
flush holes are placed strictly near the center line of the bit in order to
help the flushing medium, usually compressed air for quarry drilling, to more
effectively push the rock cuttings away from the bit center towards the bit
edge; the flush holes are located within newly designed, V-shaped flushing
grooves. The tungsten buttons are placed strategically around and between the
flushing holes and grooves such that the carbide buttons contact the rock most
effectively with each percussive impact from the bit to the rock face.
