Use of XR350 Min-drills to drill 50 ft holes at Warragamba Dam in Australia, for grouting of foundation rock; use of bits with angle of 60° included in taper resulted in increase of footage per bit, better diamond recoveries, and faster and smoother drilling; design of reamer to give directional stability.
