                                          Iadc127 Steel Tooth Tricone Bit For Water Well Drilling Bit

Description:
Tricone Milled Tooth Bits( MT):
The Steel tooth bits have their cutting structure machined out of the special steel cone forging, this
type of tricone bits are basically used for drilling soft to medium hard strata.The profile, size,
number of cutting teeth and leg off-set varies from one bit to another depending upon the strata
condition for which it is designed . The tooth points of each cone are inter-fitted with adjacent
cones;this provides for mechanical cutting, gouging and scraping action during drilling.

Steel tooth Bits are of basically three types:-
1).Soft Formation Bit – These are bit designed for drilling soft strata having less comprehensive 
strength and high drilling ability generally includes clay, shale, etc .In such bits the tooth points
are widely spaced and are of greater length to allow maximum penetration into the formation,
resulting in removal of large chips. These bits are generally run with lesser weight on bit and
higher rotation speed. Maximum cone off-set   (usually 5 degree) is maintained for such bit;
this results in maximum scraping – twisting action on hole bottom during drilling. A considerable
amount of special hard-facing alloy is applied on the complete tooth to enhance the bit life.

2).Medium Formation Bit – These are bit designed for drilling medium formation with higher
comprehensive strength such as hard limestone, dolomite and hard shale. In such bits the tooth
points are closely placed,and are of lesser height as a result the number of teeth’s are increased.
During drilling the weight on bit is required to be more with lesser rotation speed. Moderate cone
off-set (usually 3 degree) is maintained which results in chip & crush cutting and only slight
twisting action during drilling. The flanks of the teeth’s the gauge and the leg shirttail are hard-
faced for abrasion resistance. 

3).Hard Formation Bit – These are bit designed for drilling hard and abrasive formation such as
limestone,dolomite, sandstone, and graphite. In such bit the teeth’s are relatively shallow and the
number of teeth is more so that individual tooth load is not too great. The cone off – set is
generally nil to give the cone a true rotation resulting in less gouging and scraping action and
more of chipping and crushing action. A good amount of hard-face and/or Tungsten Carbide
Insert are provided in the cone gauge and shirttail portion of the leg to elongate the life of the bit
in toughest drilling conditions.
