Cone offset

  1. - It forces the cone to rotate around the axis of the bit
  2. - The cone slips as it rotates causing tearing and gouging action
  3. - Amount of offset directly relates to the strength of drilled rock
  4. - Large offset used for soft formation
  5. - Hard brittle rock need no offset
  6. - Medium hard rock need up to 2 offset
  7. - The degree of offset is defined as the horizontal distance between the axis of the bit and a vertical plane through the axis of the journal
