The above chart represents commonly available sizes and types, we do produce other sizes and types of rock bits which do not appear on this list. Please contact us for more information.
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
