Drilling Mechanisms Of Tricone Drill Bits These mechanisms include: Crushing: The teeth on the cones exert downward pressure on the rock, causing it to crush and break apart. Chipping: As the teeth make contact with the rock, they chip away at the surface, creating small rock particles. Scrape: The rotating cones scrape and grind the rock, helping to remove material from the hole. Erosion: The rotational movement of the cones causes erosion on the rock surface, contributing to the drilling proce
