High quality&Factory price-tricone bit(tci)
Description of tricone bit:
Tricone bits also named roller bits, typically they are used for oil & gas drilling, but now tricone bits are also used for mining, quarrying, water well drilling, etc.
This particular bit was developed by engineers from the Sharp-Hughes Tool Company in 1933 using the company's two cone bits as a base design. The original two cone bit design featured a pair of opposed rotating cones fitted with rows of teeth. When rotated against a rock face on the end of a drill string, the dual axis rotational friction on the head teeth abraded the rock material to form a hole. The tricone bit followed the design concept fairly closely with the exception of the addition of a third bit head. This configuration proved to be far more efficient, thereby drilling faster and with less wear to the individual bit heads.
The basic concept which underpins the efficiency of rotating cone drill bits is the dual axis action of the bit. When drilling, the bit body turns around its own axis while the heads themselves revolve around theirs at an angle to the body axis. This multi-axis action is a particularly effective cutting mechanism, thus making the tricone bit a common choice for deep drilling operations. The design is also cos
t effective because the three drill heads improve the bits wear to drill advancement ratio.
