ROLLER CONE BIT CONE DESIGN
Cone slippage can also be attained by offsetting the axes of the cones. This is often used in soft formation bits . To achieve an offset the journals must be angled slightly away from the centre. Hard formation bits have little or no offset to minimise slippage and rely on grinding and crushing action alone.
