PURPOSE: A detachable rod for a breaker is provided to expand the life span of the rod, the breaker, and an excavator by reducing the wear of a pointed unit of the rod, to improve working efficiency by quickly and easily replacing the pointed unit when the pointed unit is worn out, and to maximally reduce cost for the expendable rod by replacing only the front end of the rod. CONSTITUTION: A detachable rod(10) for a breaker is composed of a rod unit(11) mounted to the breaker; a front end unit(12) detachably combined to the outer front end of the rod unit by a combining device to form the outer front end of the rod; and a pointed unit(13) of high hardness attached and installed to the end of the front end unit. The combining device comprises a bolt and a nut formed at the rod unit and the front end unit, respectively; a spring washer(22) inserted between the rod unit and the front end unit; holes formed at the sides of the bolt and the nut to communicate each other in combining the rod unit and the front end unit; and a combining pin(25) penetrated and installed to the hole.
