摘要： A cutting element includes a cutting end extending a depth from a cutting face to an interface surface opposite from the cutting face, and a spindle, the spindle axially separated from the cutting end by a transition region. The spindle has a spindle diameter measured between a spindle side surface, which is less than a cutting end diameter. A guide length, measured from a point of transition to the transition region to a retention feature, is longer than 75% of a total length of the spindle.
