Trait:single row、7 spiral blades、7 water holes

 

Suitable for medium hard formations with high compressive strength and abrasiveness

   Mudstone、quartz sandstone、dolomite…

 

Sintered with high-quality tungsten carbide material

   Excellent erosion resistance

 

Structure of long parabola shape with spiral deep blade、anti-rotation design

   Maximize the abrasion resistance and stability of bit
   Increase the mechanical penetration rate and stability of the bit

 

Reasonable configuration of high-quality PDC cutters

   Optimize the tooth distribution structure、increase the attack ability and wear resistance of the bit

 

Lengthen gauge

   Increase the compression resistance and lateral stability of the bit

 

 

Reduce lateral offset、improve the quality of borehole

   Design of adding limiting cutters to the inner cone

 

Better control the depth of the bit into the formations

   Avoid early collapse of PDC cutters

 

Optimize water conservancy structure

   Design of bottom hole flow field、beneficial to the chips removal and the mud bags prevention
