Abstract:
A cutting pick comprising a cutting tip 10 formed such as from SiC-D and a metal pick body 11. The pick body 11 has a greater coefficient of thermal expansion than the cutting tip 10. The pick body 11 includes a generally cylindrical cavity 14 within which is received a generally cylindrical anchor portion 13. The tip 10 includes a coating 17 bonded to the outer surface of the anchor portion 13. An annulus 24 is left between the coating 17 and the cavity 14 within which is a solder or braze material which bonds to each of the coating 17 and the cavity 14. The pick body 11 employs the difference in thermal expansion to exert pressure on the anchor portion 13 to fix the tip 10 to the pick body 11.
