HARDROCK HDDP Rock Hammer Bit
The patent pending HARDROCK HDDP rock hammer bit is made so that a puller can be attached to the end of a drill bit. The puller diverts air flow backward and forward to remove any debris left in the bore hole, and the back of the bit has carbide chiseled teeth to help cut its way back to the drill. This bit was made, when the hammer was in a difficult situation, to break loose from the drill string. It can also be used to insert product in a pilot bore.
The patent pending HARDROCK HDDP rock hammer bit fits the Hardrock range of hammers (HDDP50, HDDP60), and most other hammer systems on the market.
