Manufacture of boring bit inserts

  • Published:
Soviet Powder Metallurgy and Metal Ceramics Aims and scope

Conclusions

  1. 1.

    A new, improved method has been developed for the manufacture of boring bit inserts by the powder metallurgy technique.

  2. 2.

    It has been established that the strength of boring bits with the experimental inserts is one and a half times higher than that of standard bits, as a result of which their useful life is 12% longer at an increase in drilling speed of 10%.

  3. 3.

    The improved performance of the experimental inserts is a result of the formation of an optimum iron-copper-body/hard-alloy-blade composite structure.
