Abstract
A bit breaker is formed of a U-shaped base and latchable gate which closes the U. When the gate is in a closed position, evenly spaced chocks on both the base and gate protrude into the central cavity of the bit breaker to engage slots formed in the bit. The bit breaker is designed to be used with either roller cone bits or drag bits.
