Bulroc Hyper 66 / DHD 360 Deep Hole Hammer

6" to 8" diameter holes

The Hyper 66DH is a valveless DTH Hammer specifically designed to operate efficiently at depths and overcome high heads of water. The combined control tube, diverter, and check valve minimize the number of component parts, reducing the overall length of the hammer for ease of handling.

The Hyper 66DH is supplied as standard with a 3 1/2" API regular pin backhead and a chuck to accept Button Bits with Ingersoll Rand DHD360 shanks. Alternatively, the Hyper 66DH can also be supplied with chucks to suit most other major types of Button Bits, including IR Q160.
