Impactor, as basic equipment in drilling project, is widely used in mining with common machines of hydraulic pressure impactor and pneumatic hammer. In drilling rig project, you should select high quality bits for high efficiency and quick drilling. Thus we should choose different bits with different drilling ways and rock types. The bits end face structure, tank figures, and bits hardness will influence the drilling speed, rig quality, service life, working efficiency, and so on. So it is important in selecting proper drilling rig.

    Now, the common impactor bits have four types of flat, convex, concave, and deep concave end face.

    Flat end face: These kinds of impactor have the feature of hard and wear resistance that adopts in hard and hardest rocks and lower blast hole requirement of medium and soft hardness rocks.

    Convex end face bit: this kind of impactor bits can have higher speed in drilling medium and hard rocks. While this kind of drill hole has worse flatness.

    Concave end face: this impactor has a cone concave parts that can have a light nucleation function in drilling that makes bits have fine lining trail in medium blast hole. Besides, these bits have fine powder discharge and quick drilling speed that is popular in market.

    Deep concave with central types end face: this kind of impactor has a core parts for nucleation. Deep drilling make blast hole have high flatness and lower end face that adopts to soft and medium hardness rocks.

    Now there are four kinds of impactor bits with different rock performances and demands.
