| description | An improved drill bit includes a bit body, a coupling member formed at an upper shank portion. It further includes at least one sensor for monitoring at least one condition of the bit during drilling operations. In one embodiment the at least one sensor is a capacitor disposed in a lubrication pathway. An electronics bay is defined in-part by the upper shank portion. It houses at least one monitoring circuit. A battery cavity is disposed in at least one of the bit legs. A battery cavity cap is provided. A seal is provided to seal the battery cavity cap at the bit leg to define a fluid tight battery cavity. |
