ABSTRACT:
An apparatus for a percussive, down-hole drill, for positioning a split retaining ring against an internal surface of a drill casing including a chuck with a tapered top surface, a bit bearing with a tapered bottom surface, and a reversible split retaining ring sandwiched therebetween, the split ring having a tapered top and bottom surface, each tapered surface subtending an angle between 5.7 and 25 degrees, as measured from a perpendicular to a drill longitudinal axis, whereby a portion of any longitudinal load on the split ring is developed into a preselected maximum and minimum amount of radial load, to position the split ring in the casing, without damaging the casing.
