Big Hole Drill Bits Down The Hole DTH Hammer Bits 1, valveless air distribution. More reliable. 2, simple design of the piston, long life. 3, More efficient energy transfer, faster drilling speed, lower air consumption and lower oil consumption. 4, fewer internal parts, simple structure, longer life, less failure and easier to maintain becayse all the parts are heat treated. 5, It is easy to disassemble because the top sub, the drive chuck and the external cylinder are connected by multi-step thread.

RC4.5 RC5.5 Remet or Metzke Thread Connection RC Drilling Hammer for Geological Exploration Reverse Circulation (RC) drilling is used to collect mineral and rock samples quickly and efficiently using a large rotary drill and air compressor. Reverse Circulation (or RC) drilling is one of the most frequently used methods of drilling used across the world as it is more cost effective and efficient then other methods of drilling
