Wide varieties of roller cone bits are readily available. They supply optimum performance in particular formations and/or special drilling environments. Modern drill pieces incorporate significantly distinct cutting constructions and use enormously enhanced substances, resulting in enhanced little efficacy.

Rolling filler pieces, which some might also involve roller cone bits or tri-cone pieces, have three cones. Each cone could be rotated separately as soon as the drill string rotates the entire body of this piece. There are two sorts of roller bit pieces that are milled-tooth pieces and tungsten carbide inserts (insert pieces ).
