Introduction
Medium to medium hard formation is suitable for medium abrasive consolidated formation with compressive strength between 140 – 485 Mpa, such as hard limestone, quartzite, granodiorite and medium grade metamorphic rock cutting structure: these bits are characterized by medium spacing conical blades and medium protrusion. This configuration can improve the good penetration rate of medium hardness and medium abrasive formations. Provide smaller hard alloy blades on gauges and inner rows, or deposit hard metal in the tip area to contain shell erosion and improve performance.

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.
