A rotary tricone roller drill bit is a type of borehole drill bit, a popular water well borehole drill bit, a rotary tricone roller drill bit has three rollers on the drill bit’s head, each of round rollers are covered with different teeth. When drilling a water well borehole the round roller will rotate itself and this borehole drill bit is also called water articulated drill bit, it is because when drill a water well borehole, it needs water to drill. It is a low drilling cost to drill a water well borehole.
There are two types of rotary tricone roller drill bit, one type is steel teeth rotary drill bit which is called milled tooth drill bit, the other type is called tungsten carbide insert teeth rotary drill bit which is called TCI roller drill bit. These types of rotary tricone roller drill bits can be used to drill through rocks, the different shape of teeth can drill through different hardness of rocks. The formations of the earth is very important for using this borehole drill bit, such as there are less hard rock formations under the ground and the rocky formation area is covered with small rocks.
Check the specifications of the borehole drill bits, click the link bellow.
- DTH drill bit, a kind of compressed air drill bit.
- Tricone drill bit, a kind of water circular drill bit.
- PDC drill bit, uses water to drill.
- Drag drill bit or core drilling bit, uses water to drill.
A rotary tricone roller drill bit is a type of borehole drill bit that is used for drilling a water well borehole or drilling an oil borehole. It is a cheap borehole drill bit, since it uses water to drill, the DTH borehole drill bit needs a screw air compressor to drill, and the drilling cost is a higher. The other characteristic of the rotary tricone roller drill bit is that the contact of the borehole bottom for the rollers on the drill bit is small, so this increases the durability of the rotary tricone roller drill bit.
