DTH Quad / Cluster Drill Reverse Circulation Hole Boring Hammer

The Quad Drill contains a number of closed loop top exhaust hammers with unique four sided elliptical bits with ramps angle gauge that can index four times to allow all gauge surfaces to be used.  When the bit drops, the air is shut off to the individual hammer and diverted to the remaining hammers with closed bits.  This allows the Quad Drill to operate on uneven and fractured surfaces.
