Sollroc 6'' DTH Hammer For Blasting Drilling

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 drilling tool is a kind of drilling system which uses compressed air as motivation, makes drilling impact motivation parts down the hole, to control the piston reciprocating motion by the distribution device in the hammer, and then impacts the DTH bit in the front of the hammer to transit the impacting power to the bit. The DTH bit in the front of the hammer breaks the rock to drill hole. Product featutres: 1. Simple design of the piston. Long life. Valveless air distribution. More reliable. 2. More efficient energy transfer, fact drilling speed, lower air consumption and lower oil consumption. 3. Fewer internal parts, simple structure, long life, less failure and easier to maintain because all the parts are heat treated. 4. Easy to disassemble because the top sub, the drive chuck and the external cylinder are connected by multi-step thread.
