As a tool for drilling rock formations, cone drills have been widely used. Significant improvements in drill performance have directly reduced drilling costs, especially the fastest progress in the past decade. Service life and drilling speed Performance indicators, they finally determine the degree to which the drill bit affects the cost of drilling. Increasing the mechanical drilling speed and service life of the drill bit is an effective way to reduce the cost of drilling. Some data have confirmed that the improvement of the drilling speed than the improvement of the life of the bit has an effect on reducing the cost Larger, in which the improvement of the cutting structure of the bit is the most direct method to increase the mechanical drilling speed of the bit.
