Abstract
A drill bit nozzle includes a nozzle body, a channel in the nozzle body, and a nozzle outlet arranged at an end of the nozzle body and in communication with the channel. The nozzle outlet is a strip-shaped outlet configured to eject a sheet-like jet flow. Since the nozzle outlet of the drill bit nozzle is a strip-shaped outlet, the nozzle outlet is able to eject a sheet-like jet flow. When the drill bit nozzle is applied to a PDC drill bit, the drill bit nozzle can uniformly eject a drilling fluid onto each cutting tooth, which ensures that the cutting teeth in the drill bit may obtain good cooling and chip removal effects, while avoiding excessive concentration of the jet flow from the drill bit nozzle which may erode the cutting teeth, thereby prolonging the service life of the drill bit.
