Abstract: The cone cutter of each segment of a multi-segment rock bit is assembled onto its segment. A pin end of the segment is supported by an index pin and axially constrained in the direction away from the cone cutter. The cone cutter is clamped against and dimensionally indexed on a cone saddle having a circular surface of a diameter corresponding to the gage diameter of the completed rock bit. The cone is loaded in a direction axially of the segment in a manner to simulate the loading of the hole bottom that is to be drilled by the rock bit. The segment away from the cone is also loaded radially of the axis of the segment to take up tolerances along the axis of rotation of the cone cutter. The constraint of the cone and loading of the segment simulate the hole wall force on the cone experienced at the gage row and takes up tolerances radially of the axis of rotation of the cone along a line to the gage row in contact with formation material. A bridge prevents rotation of the segment about its lengthwise axis.
