In this paper results of experimental studies of ice cutting  process  with  using cutter  type bits are presented. The bit operation, ranges of rational value of bit taper and rate of penetration  are analysed. Reasons causing complications during drilling well in ice deeper then 3000m are determined on the basis well drilling in Vostok station and Dom C and possible ways to overcome them.
