Bosch MAX X 9/16X8/13

SDS-Max standard bits seat their shank securely in rotary hammers with an SDS-Max chuck, enabling piston-like action without slipping during high-torque drilling. They have longer, thicker shanks for drilling larger holes and applying greater force than SDS-Plus bits. SDS-Max bits are commonly used for pipe running, rebar doweling, concrete repair, channel grooving, light demolition, and other heavy-duty concrete-drilling jobs.
