Fixed nozzle port retention mechanism

An earth-boring tool, comprising:

• a drill bit body having at least one blade and at least one nozzle cavity, the at least one nozzle cavity comprising a generally tubular shape, and the at least one nozzle cavity comprising a first groove that comprises a first depressed channel inset into an interior surface thereof and extending around the nozzle cavity;
• a nozzle disposed in the at least one nozzle cavity, the nozzle comprising a generally cylindrical shape and comprising a second groove that comprises a second depressed channel inset into an external surface thereof and extending around the nozzle, the second groove at least partially overlapping the first groove, and the first groove and the second groove forming a space between the nozzle and the at least one nozzle cavity;
• and
• a sealant disposed in and substantially filling the space between the at least one nozzle cavity and the nozzle.

A drill bit comprising:

• a plurality of blades;
• cutting elements disposed on the plurality of blades;
• fluid courses disposed between the plurality of blades;
• a first outlet disposed in a first fluid course of the fluid courses;
• a second outlet disposed in a second fluid course of the fluid courses;
• a fixed port nozzle disposed in the first outlet, the first outlet defining a nozzle cavity, and the fixed port nozzle being disposed in the nozzle cavity;
• a sealant disposed between an outer surface of the fixed port nozzle and an inner surface of the nozzle cavity, the sealant bonding the fixed port nozzle to the nozzle cavity, and the sealant comprising an epoxy or a monomer;
• and
• a removeable nozzle disposed in the second outlet, wherein
• the nozzle cavity comprises a first groove forming a first depressed channel inset into an interior surface thereof;
• the fixed port nozzle comprises a second groove forming a second depressed channel inset into an exterior surface thereof, the second groove at least partially overlapping the first groove, the first groove and the second groove forming a space between the nozzle cavity and the fixed port nozzle;
• and
• the sealant is disposed within the space, the sealant within the space configured to provide a mechanical lock between the nozzle cavity and the fixed port nozzle.
