Wear resistance of teeth of conventional steel tooth cone bit is not good, tooth shape structure is lack of optimization, which leads to decrease of average ROP. AMR series steel tooth bit with high efficiency can solve these problems, with strong wear resistant teeth and fast ROP, bit can work more stably, which is more suitable for drilling in soft or middle soft formations with high rotary speed.
Application of AMR series steel tooth bit with high efficiency is the best way to solve the problem of increasing drilling speed in higher part of well.

AMR series steel tooth bit with high efficiency has strong wear resistant teeth and last ROP bit can work more stably which is more suitable lor drilling in soft or middle soft formations.

The size range of AMR series bit is 8 1/2 - 17 1/2 inch such as 8 3/8, 8 1/2, 8 5/8, 8 7/8, , 9 1/2, 9 7/8, 10 5/8, 11, 11 5/8, 12 1/4, 12 3/4, 13 3/8, 13 1/2, 13 5/8, 14 1/2, 14 3/4, 15 1/2, 16, 17 1/2 and its IADC code is 117  - 127  (or  115 - 125).

Optimized structure design of cutter  shape  is thickened hardfacing on surface and crest of cutters  to enhance aggressiveness for cutters. Enhanced hardfacing  on leading  edge and training edge of cutters improve wear-resistance of cutters.
