444.5mm 17 1/2 Inch Tci Tricone Drill Bits In Soft Formation

The shearing effect of teeth itself is also an important cutting method that cannot be ignored. Under the action of drilling pressure and drill string rotation, teeth can crush and feed into the rock, while producing a certain amount of sliding, further shearing the rock. This shear action can remove the remaining rock between the teeth, causing the rock at the bottom of the well to break completely and extend the wellbore. The cutting method of a three cone drill bit is a composite process that combines impact crushing, sliding shear, and the shear effect of the teeth themselves, allowing the drill bit to adapt to various formation types and achieve efficient and stable drilling.
