  • Ceramic bit for high speed drilling
    Patent number: 7367758
    Abstract: A ceramic drill bit comprising a cylindrical shank and a shaped portion extending axially in line with the shank and having a free end forming the tip of the bit, a relief face extending from each main cutting edge with a relief angle lying in the range 4° to 10° approximately relative to a plane perpendicular to the axis of rotation of the bit, and two notches forming two secondary cutting faces extending from the central edge with positive cutting angles lying in the range 1° to 7° approximately relative to the axis of rotation of the bit.

  • METHOD FOR DETECTING AND QUANTIFYING DRILLING ANOMALIES
    Publication number: 20080047333
    Abstract: A method for detecting and optionally a method for quantifying drilling anomalies in a metal part. The drilling method includes determining a value set of at least one of the two following parameters, depending on the time: the penetration axial stress of a drill bit into the metal part and the torque generated during at least one portion part of the drilling.
