TriconeBits
The tricone bit is the most commonly used drilling tool. It is fixed to the lower
end of the drill collars which are in turn attached to the drill pipes, these being driven
by the rotary movement of the turntable. This drilling tool can drill through several typesof different rock structure, which is why they are they most commonly used.
Tricone bits are assemblies of three rotating cones which cut through the rock by their
rotary action. The cones are fitted with longer or shorter points depending on the
resistance or hardness of the rock, and teeth for softer rock. The points are made from tungsten carbide for the hardest rock. The effectiveness of a tricone bit depends on its capacity to crush the rock and remove the pieces - the tricone bit therefore
works by Percussion, Penetration and Extraction.
