  • THREADED NOZZLE FOR A CUTTER BIT
    Publication number: 20090321145
    Abstract: A threaded nozzle for use in a cutter bit is disclosed. Threads are either machined into or pressed into a pressed powder nozzle then the nozzle is sintered. Threads of the nozzles of the present invention exhibit improved hardness and have a rougher surface finish than threads machined post-sintering. Shaping of the threads into the nozzle before sintering is also more economical and efficient than post-sintering machining.
