摘要
A drill bit includes a bit body defining a rotational axis, a plurality of blades on the bit body, a plurality of cutting elements on the plurality of blades, each cutting element defining a sweep profile about the rotational axis, a first depth of cut controller (DOCC) movably secured to one of the plurality of blades and movable in response to contact by a formation when drilling, and a second DOCC movably secured to the one of the plurality of blades, the second DOCC coupled to the first DOCC such that movement of the first DOCC changes a height of the second DOCC relative to a height of the first DOCC.
