Introduction
The roller tapered drill bit has a conical tool or body with steel teeth or tungsten carbide buttons around it. When the drill string rotates, the drill cone rolls in a circular motion along the bottom of the borehole. When they roll, the new teeth come into contact with the bottom of the hole, causing the strata below and around the drill teeth to break.

Features
1. High strength, high elasticity, high temperature resistance, high wear resistance.
2. High precision metal seal.
3. Lock the balls to adapt to high speed.
4. Using high-strength and high-toughness carbide teeth,
5. The hour cone bit has the function of impacting, breaking and shearing broken rocks.
6. The roller cone bit adapts to the soft, medium and hard of various formations.
7. Reasonable price and long service life.
Used in
Tri-cone bit is a decelerating bit. It is based on the fact that
the speed of the cone is less than the speed of the bit. It is
suitable for sidetracking of old wells and deepening of small
boreholes under high speed and high drilling pressure.
