A fixed rotary drill bit, especially the type rotary drill bits incorporating a plurality of spaced polycrystalline diamond compact (PDC) cutters or cutting elements on a plurality of radial blades, includes multiple tungsten carbide inserts (TCI) spaced between the PDC cutters or cutting elements, each TCI providing a mitigation to vibration for the drill bits, rapidly adapting the TCIs by wear from the intermediary formation ridges created from drilling resulting in the creation of a unique kerf in each TCI, thus increasing stability of the bit from lateral instability, making the drill bit more efficient, and promoting a continual steady state of drilling.
An improvement to a fixed rotary drill bit defining a singular cast body forming a lower threaded end, lateral rounded margins, and an upper surface defining a plurality of fixed blades, each blade forming a plurality of spaced cutting element sockets, each cutting element socket containing an individual cutting element, said improvement comprising:
