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
