Inc.'s EDM (Exploration Drill Masters) 95K that's used for oil and
gas drilling, small water wells, and core work drills a 5000-foot
HQ (core bit) core hole at an 80° angle at a mine in Nevada. It
is a dual-purpose rig so it can easily switch back and forth from
core to rotary when needed. National Exploration, Wells & Pumps
also uses it to drill flooded reverse rotary typically with an 8¾-inch
tricone bit up to 2500 feet. Photo courtesy John Fowler, CSP, CMSP,
