RC4.5-E542 RC4.5-E543 Reverse Circulation RC Drill Bit Fit Shank RE542 RE543
Unlike diamond drilling, it compiles sample rock cuttings instead of rock core. The drilling mechanism is most often a pneumatic reciprocating piston called a hammer, which in turn is driving a tungsten-steel drill bit, specifically made to be able to crush hard rock.
Reverse circulation is achieved by blowing air down the annulus of the rod, the differential pressure creating air lift of the water and cuttings up the inner tube which is inside each rod. It reaches the deflector box at the top of the drill string then moves through a sample hose which is attached to the top of the cyclone.
SOLLROC are offering high performance RC hammers and bits. Our hammers and bits have improved by testing many sites all over the world.
