2.The design of the product structure:

(1)Cutting structure:

In response to the characteristics that inserts in different areas on the cone have different

cutting actions, conical inserts are placed in permanent contact area and wedge inserts are

placed in alternative contact area so that the drilling efficiency is greatly improved. Wear

resistance of cutting structure is enhanced by setting diamond inserts in the permanent

contact area of the cone Where inserts are severely worn. Tungsten carbide inserts are

placed on cone top face to protect cone body from abrasive erosion.

(2) Gauge Structure:

With active cutting gauge protection inserts on bit body, the bit has good gauge protection
