What is Roller Cone Bit?
Roller Cone Bit - a drilling method that uses a roller bits. In roller-bit drilling, rock is cut by hard-alloy teeth projecting from rolling cutters, which rotate on the drill-bit bearings. Inturn, the drill bit rotates at a high rate, and presses against the bottom hole with a high axial force. The teeth of the rolling cutters roll over the bottom hole and, owing to the large stresses that develop in the area of contact between the teeth and the rock, cut the rock by crushing and chipping. As the hardness of therock increases, the rotation rate decreases and the axial force increases. Destroyed at the mine the rock is removed to the surface by air compressor, mud pump, or a combination of these methods.

This Series Of Rock Roller Bits Can Apply For Drilling Hard To Very-Hard Formation.
Application : For use in abrasive consolidated formations with compressive strength above 400 Mpa such as taconite, quartzite and banded iron formations
Cutting structure: These bits are characterized by closely spaced conical or spherical inserts with medium to low projection. This configuration promotes good penetration rates in hard, consolidated and very abrasive formations. Smaller carbide inserts are provided on the gage and inner rows or hard metal is deposited in the nose area to contain shell erosion and improve performance.
