Cone offset
- 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 - 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
