The more aggressive Carbides assist movement of the chips away from the face as there is more room for airflow on the face of the Bit. These more aggressive Bits help to break out larger chips, which increases the penetration rate. The greater volume of Carbide can lead to longer Bit life.Button ShapeApplicationSphericalSpherical Carbides for use in medium to hard rock, with fractured or seamy applications.Semi-ballistic Semi-ballistic shaped, more aggressive than the Spherical Carbides, for soft to medium consistent rock.Ballistic Bullet shaped, very aggressive fast penetration in soft to medium consistent rock.Key Words:R25 Tunneling Thread Button BitsR25 Threaded bit,thread button bit,R25 button bitR25 Button Bit for for Drifting and TunnelingThread Button Bit for for Drifting and TunnelingButton Bit for for Drifting and TunnelingButton Drill Bit for for Drifting and Tunneling
