Cone offset of the roller cone bit


- 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
- It forces the cone to rotate around the axis of the bit
- The cone slips as it rotates causing tearing and gouging action
- Amount of offset directly relates to the strength of drilled rock
- Large offset used for soft formation
- Hard brittle rock need no offset
- Medium hard rock need up to 2 offset
